release candidate for InvokeAI 2.0

- Added support for pyreadline3 so that Window users can benefit.
- Added the !search command to search the history for a matching string:
~~~
!search puppies
[20] puppies at the food bowl -Ak_lms
[54] house overrun by hungry puppies -C20 -s100
~~~
- Added the !clear command to clear the in-memory and on-disk
  command history.

+
+Multimodal generative models are being widely adopted and used, and
+have the potential to transform the way artists, among other
+individuals, conceive and benefit from AI or ML technologies as a tool
+for content creation.
+
+Notwithstanding the current and potential benefits that these
+artifacts can bring to society at large, there are also concerns about
+potential misuses of them, either due to their technical limitations
+or ethical considerations.
+
+In short, this license strives for both the open and responsible
+downstream use of the accompanying model. When it comes to the open
+character, we took inspiration from open source permissive licenses
+regarding the grant of IP rights. Referring to the downstream
+responsible use, we added use-based restrictions not permitting the
+use of the Model in very specific scenarios, in order for the licensor
+to be able to enforce the license in case potential misuses of the
+Model may occur. At the same time, we strive to promote open and
+responsible research on generative models for art and content
+generation.
+
+Even though downstream derivative versions of the model could be
+released under different licensing terms, the latter will always have
+to include - at minimum - the same use-based restrictions as the ones
+in the original license (this license). We believe in the intersection
+between open and responsible AI development; thus, this License aims
+to strike a balance between both in order to enable responsible
+open-science in the field of AI.
+
+This License governs the use of the model (and its derivatives) and is
+informed by the model card associated with the model.
+
+NOW THEREFORE, You and Licensor agree as follows:
+
+1. Definitions
+
+- "License" means the terms and conditions for use, reproduction, and
+  Distribution as defined in this document.
+
+- "Data" means a collection of information and/or content extracted
+  from the dataset used with the Model, including to train, pretrain,

-My development machine is a GPU node in a high-performance compute
-cluster which has no connection to the internet. During model
-initialization, stable-diffusion tries to download the Bert tokenizer
-and a file needed by the kornia library.  This obviously didn't work
-for me.
+### Installation
 
-To work around this, I have modified ldm/modules/encoders/modules.py
-to look for locally cached Bert files rather than attempting to
-download them. For this to work, you must run
-"scripts/preload_models.py" once from an internet-connected machine
-prior to running the code on an isolated one. This assumes that both
-machines share a common network-mounted filesystem with a common
-.cache directory.
+This fork is supported across multiple platforms. You can find individual installation instructions
+below.

-[Stable Diffusion](#stable-diffusion-v1) is a latent text-to-image diffusion
-model.
-Thanks to a generous compute donation from [Stability AI](https://stability.ai/) and support from [LAION](https://laion.ai/), we were able to train a Latent Diffusion Model on 512x512 images from a subset of the [LAION-5B](https://laion.ai/blog/laion-5b/) database. 
-Similar to Google's [Imagen](https://arxiv.org/abs/2205.11487), 
-this model uses a frozen CLIP ViT-L/14 text encoder to condition the model on text prompts.
-With its 860M UNet and 123M text encoder, the model is relatively lightweight and runs on a GPU with at least 10GB VRAM.
-See [this section](#stable-diffusion-v1) below and the [model card](https://huggingface.co/CompVis/stable-diffusion).
+- At least 6 GB of free disk space for the machine learning model, Python, and all its dependencies.
 
-  
-## Requirements
-A suitable [conda](https://conda.io/) environment named `ldm` can be created
-and activated with:
+#### Note
 
-```
-conda env create -f environment.yaml
-conda activate ldm
+Precision is auto configured based on the device. If however you encounter
+errors like 'expected type Float but found Half' or 'not implemented for Half'
+you can try starting `dream.py` with the `--precision=float32` flag:
+
+```bash
+(ldm) ~/stable-diffusion$ python scripts/dream.py --precision=float32
 ```
 
-You can also update an existing [latent diffusion](https://github.com/CompVis/latent-diffusion) environment by running
+### Features

-## Stable Diffusion v1
+#### Other Features
 
-Stable Diffusion v1 refers to a specific configuration of the model
-architecture that uses a downsampling-factor 8 autoencoder with an 860M UNet
-and CLIP ViT-L/14 text encoder for the diffusion model. The model was pretrained on 256x256 images and 
-then finetuned on 512x512 images.
+- [Creating Transparent Regions for Inpainting](docs/features/INPAINTING.md#creating-transparent-regions-for-inpainting)
+- [Preload Models](docs/features/OTHER.md#preload-models)
 
-*Note: Stable Diffusion v1 is a general text-to-image diffusion model and therefore mirrors biases and (mis-)conceptions that are present
-in its training data. 
-Details on the training procedure and data, as well as the intended use of the model can be found in the corresponding [model card](https://huggingface.co/CompVis/stable-diffusion).
-Research into the safe deployment of general text-to-image models is an ongoing effort. To prevent misuse and harm, we currently provide access to the checkpoints only for [academic research purposes upon request](https://stability.ai/academia-access-form).
-**This is an experiment in safe and community-driven publication of a capable and general text-to-image model. We are working on a public release with a more permissive license that also incorporates ethical considerations.***
+### Latest Changes
 
-[Request access to Stable Diffusion v1 checkpoints for academic research](https://stability.ai/academia-access-form) 
+- vNEXT (TODO 2022)
 
-### Weights
+  - Deprecated `--full_precision` / `-F`. Simply omit it and `dream.py` will auto
+    configure. To switch away from auto use the new flag like `--precision=float32`.
 
-We currently provide three checkpoints, `sd-v1-1.ckpt`, `sd-v1-2.ckpt` and `sd-v1-3.ckpt`,
-which were trained as follows,
+- v1.14 (11 September 2022)
 
-- `sd-v1-1.ckpt`: 237k steps at resolution `256x256` on [laion2B-en](https://huggingface.co/datasets/laion/laion2B-en).
-  194k steps at resolution `512x512` on [laion-high-resolution](https://huggingface.co/datasets/laion/laion-high-resolution) (170M examples from LAION-5B with resolution `>= 1024x1024`).

-![txt2img-stable2](assets/stable-samples/txt2img/merged-0007.png)
+### Troubleshooting
 
-Stable Diffusion is a latent diffusion model conditioned on the (non-pooled) text embeddings of a CLIP ViT-L/14 text encoder.
+Please check out our **[Q&A](docs/help/TROUBLESHOOT.md)** to get solutions for common installation
+problems and other issues.
 
+# Contributing
 
-#### Sampling Script
+Anyone who wishes to contribute to this project, whether documentation, features, bug fixes, code
+cleanup, testing, or code reviews, is very much encouraged to do so. If you are unfamiliar with how
+to contribute to GitHub projects, here is a
+[Getting Started Guide](https://opensource.com/article/19/7/create-pull-request-github).
 
-After [obtaining the weights](#weights), link them
-```
-mkdir -p models/ldm/stable-diffusion-v1/
-ln -s <path/to/model.ckpt> models/ldm/stable-diffusion-v1/model.ckpt 
-```
-and sample with
-```
-python scripts/txt2img.py --prompt "a photograph of an astronaut riding a horse" --plms 
-```
+A full set of contribution guidelines, along with templates, are in progress, but for now the most
+important thing is to **make your pull request against the "development" branch**, and not against
+"main". This will help keep public breakage to a minimum and will allow you to propose more radical
+changes.
 
-By default, this uses a guidance scale of `--scale 7.5`, [Katherine Crowson's implementation](https://github.com/CompVis/latent-diffusion/pull/51) of the [PLMS](https://arxiv.org/abs/2202.09778) sampler, 
-and renders images of size 512x512 (which it was trained on) in 50 steps. All supported arguments are listed below (type `python scripts/txt2img.py --help`).

+### Support
 
-```
-Note: The inference config for all v1 versions is designed to be used with EMA-only checkpoints. 
-For this reason `use_ema=False` is set in the configuration, otherwise the code will try to switch from
-non-EMA to EMA weights. If you want to examine the effect of EMA vs no EMA, we provide "full" checkpoints
-which contain both types of weights. For these, `use_ema=False` will load and use the non-EMA weights.
+For support, please use this repository's GitHub Issues tracking service. Feel free to send me an
+email if you use and like the script.

-#### Diffusers Integration
-
-Another way to download and sample Stable Diffusion is by using the [diffusers library](https://github.com/huggingface/diffusers/tree/main#new--stable-diffusion-is-now-fully-compatible-with-diffusers)
-```py
-# make sure you're logged in with `huggingface-cli login`
-from torch import autocast
-from diffusers import StableDiffusionPipeline, LMSDiscreteScheduler
-
-pipe = StableDiffusionPipeline.from_pretrained(
-	"CompVis/stable-diffusion-v1-3-diffusers", 
-	use_auth_token=True
-)
-
-prompt = "a photo of an astronaut riding a horse on mars"
-with autocast("cuda"):
-    image = pipe(prompt)["sample"][0]  
-    
-image.save("astronaut_rides_horse.png")
-```
-

-### Image Modification with Stable Diffusion
-
-By using a diffusion-denoising mechanism as first proposed by [SDEdit](https://arxiv.org/abs/2108.01073), the model can be used for different 
-tasks such as text-guided image-to-image translation and upscaling. Similar to the txt2img sampling script, 
-we provide a script to perform image modification with Stable Diffusion.  
-
-The following describes an example where a rough sketch made in [Pinta](https://www.pinta-project.com/) is converted into a detailed artwork.
-```
-python scripts/img2img.py --prompt "A fantasy landscape, trending on artstation" --init-img <path-to-img.jpg> --strength 0.8
-```
-Here, strength is a value between 0.0 and 1.0, that controls the amount of noise that is added to the input image. 
-Values that approach 1.0 allow for lots of variations but will also produce images that are not semantically consistent with the input. See the following example.
-
-**Input**
-
-![sketch-in](assets/stable-samples/img2img/sketch-mountains-input.jpg)
-
-**Outputs**
-
-![out3](assets/stable-samples/img2img/mountains-3.png)
-![out2](assets/stable-samples/img2img/mountains-2.png)
-
-This procedure can, for example, also be used to upscale samples from the base model.
-

+# **Changelog**
+
+## v1.13 (in process)
+
+- Supports a Google Colab notebook for a standalone server running on Google hardware [Arturo Mendivil](https://github.com/artmen1516)
+- WebUI supports GFPGAN/ESRGAN facial reconstruction and upscaling [Kevin Gibbons](https://github.com/bakkot)
+- WebUI supports incremental display of in-progress images during generation [Kevin Gibbons](https://github.com/bakkot)
+- Output directory can be specified on the dream> command line.
+- The grid was displaying duplicated images when not enough images to fill the final row [Muhammad Usama](https://github.com/SMUsamaShah)
+- Can specify --grid on dream.py command line as the default.
+- Miscellaneous internal bug and stability fixes.
+
+---
+
+## v1.12 (28 August 2022)
+
+- Improved file handling, including ability to read prompts from standard input.
+  (kudos to [Yunsaki](https://github.com/yunsaki)
+- The web server is now integrated with the dream.py script. Invoke by adding --web to
+  the dream.py command arguments.
+- Face restoration and upscaling via GFPGAN and Real-ESGAN are now automatically
+  enabled if the GFPGAN directory is located as a sibling to Stable Diffusion.
+  VRAM requirements are modestly reduced. Thanks to both [Blessedcoolant](https://github.com/blessedcoolant) and
+  [Oceanswave](https://github.com/oceanswave) for their work on this.
+- You can now swap samplers on the dream> command line. [Blessedcoolant](https://github.com/blessedcoolant)
+
+---
+
+## v1.11 (26 August 2022)
+
+- NEW FEATURE: Support upscaling and face enhancement using the GFPGAN module. (kudos to [Oceanswave](https://github.com/Oceanswave)
+- You now can specify a seed of -1 to use the previous image's seed, -2 to use the seed for the image generated before that, etc.
+  Seed memory only extends back to the previous command, but will work on all images generated with the -n# switch.
+- Variant generation support temporarily disabled pending more general solution.
+- Created a feature branch named **yunsaki-morphing-dream** which adds experimental support for
+  iteratively modifying the prompt and its parameters. Please see[ Pull Request #86](https://github.com/lstein/stable-diffusion/pull/86)
+  for a synopsis of how this works. Note that when this feature is eventually added to the main branch, it will may be modified
+  significantly.
+
+---
+
+## v1.10 (25 August 2022)
+
+- A barebones but fully functional interactive web server for online generation of txt2img and img2img.
+
+---
+
+## v1.09 (24 August 2022)
+
+- A new -v option allows you to generate multiple variants of an initial image
+  in img2img mode. (kudos to [Oceanswave](https://github.com/Oceanswave). [
+  See this discussion in the PR for examples and details on use](https://github.com/lstein/stable-diffusion/pull/71#issuecomment-1226700810))
+- Added ability to personalize text to image generation (kudos to [Oceanswave](https://github.com/Oceanswave) and [nicolai256](https://github.com/nicolai256))
+- Enabled all of the samplers from k_diffusion
+
+---
+
+## v1.08 (24 August 2022)
+

+
+## **Interactive Command Line Interface**
+
+The `dream.py` script, located in `scripts/dream.py`, provides an interactive
+interface to image generation similar to the "dream mothership" bot that Stable
+AI provided on its Discord server.
+
+Unlike the `txt2img.py` and `img2img.py` scripts provided in the original
+[CompVis/stable-diffusion](https://github.com/CompVis/stable-diffusion) source
+code repository, the time-consuming initialization of the AI model
+initialization only happens once. After that image generation from the
+command-line interface is very fast.
+
+The script uses the readline library to allow for in-line editing, command
+history (++up++ and ++down++), autocompletion, and more. To help keep track of
+which prompts generated which images, the script writes a log file of image
+names and prompts to the selected output directory.
+
+In addition, as of version 1.02, it also writes the prompt into the PNG file's
+metadata where it can be retrieved using `scripts/images2prompt.py`
+
+The script is confirmed to work on Linux, Windows and Mac systems.
+
+!!! note
+
+    This script runs from the command-line or can be used as a Web application. The Web GUI is
+    currently rudimentary, but a much better replacement is on its way.

+
+The `dream>` prompt's arguments are pretty much identical to those used in the
+Discord bot, except you don't need to type "!dream" (it doesn't hurt if you do).
+A significant change is that creation of individual images is now the default
+unless `--grid` (`-g`) is given. A full list is given in
+[List of prompt arguments](#list-of-prompt-arguments).
+
+## Arguments
+
+The script itself also recognizes a series of command-line switches that will
+change important global defaults, such as the directory for image outputs and
+the location of the model weight files.
+
+### List of arguments recognized at the command line
+
+These command-line arguments can be passed to `dream.py` when you first run it
+from the Windows, Mac or Linux command line. Some set defaults that can be
+overridden on a per-prompt basis (see [List of prompt arguments]
+(#list-of-prompt-arguments). Others

+After the dream.py script initializes, it will present you with a
+**dream>** prompt. Here you can enter information to generate images
+from text (txt2img), to embellish an existing image or sketch
+(img2img), or to selectively alter chosen regions of the image
+(inpainting).
+
+### This is an example of txt2img:
+
+~~~~
+dream> waterfall and rainbow -W640 -H480
+~~~~
+
+This will create the requested image with the dimensions 640 (width)
+and 480 (height).
+
+Here are the dream> command that apply to txt2img:
+
+| Argument           |  Shortcut  |  Default            |  Description |
+|--------------------|------------|---------------------|--------------|
+| "my prompt"        |            |                    | Text prompt to use. The quotation marks are optional. |
+| --width <int>      | -W<int>   | 512                 | Width of generated image |

+| --cfg_scale <float>| -C<float> | 7.5                 | How hard to try to match the prompt to the generated image; any number greater than 1.0 works, but the useful range is roughly 5.0 to 20.0 |
+| --seed <int>       | -S<int>   | None                | Set the random seed for the next series of images. This can be used to recreate an image generated previously.|
+| --sampler <sampler>| -A<sampler>| k_lms              | Sampler to use. Use -h to get list of available samplers. |
+| --hires_fix        |           |                     | Larger images often have duplication artefacts. This option suppresses duplicates by generating the image at low res, and then using img2img to increase the resolution |
+| --grid             | -g        | False               | Turn on grid mode to return a single image combining all the images generated by this prompt |
+| --individual       | -i        | True                | Turn off grid mode (deprecated; leave off --grid instead) |

+| --skip_normalization| -x       | False               | Weighted subprompts will not be normalized. See [Weighted Prompts](./OTHER.md#weighted-prompts) |
+| --upscale <int> <float> | -U <int> <float> | -U 1 0.75| Upscale image by magnification factor (2, 4), and set strength of upscaling (0.0-1.0). If strength not set, will default to 0.75. |
+| --gfpgan_strength <float>  | -G <float> | -G0        | Fix faces using the GFPGAN algorithm; argument indicates how hard the algorithm should try (0.0-1.0) |

+| --variation <float>  |-v<float>| 0.0                 | Add a bit of noise (0.0=none, 1.0=high) to the image in order to generate a series of variations. Usually used in combination with -S<seed> and -n<int> to generate a series a riffs on a starting image. See [Variations](./VARIATIONS.md). |
+| --with_variations <pattern> | -V<pattern>| None      | Combine two or more variations. See [Variations](./VARIATIONS.md) for now to use this. |
+
+Note that the width and height of the image must be multiples of
+64. You can provide different values, but they will be rounded down to
+the nearest multiple of 64.
+
+
+### This is an example of img2img:	
+
+~~~~
+dream> waterfall and rainbow -I./vacation-photo.png -W640 -H480 --fit
+~~~~
+
+This will modify the indicated vacation photograph by making it more
+like the prompt. Results will vary greatly depending on what is in the
+image. We also ask to --fit the image into a box no bigger than
+640x480. Otherwise the image size will be identical to the provided
+photo and you may run out of memory if it is large.
+
+In addition to the command-line options recognized by txt2img, img2img
+accepts additional options:
+
+| Argument           |  Shortcut  |  Default            |  Description |
+|--------------------|------------|---------------------|--------------|
+| --init_img <path>  | -I<path>   | None                | Path to the initialization image |
+| --fit              | -F         | False               | Scale the image to fit into the specified -H and -W dimensions |
+| --strength <float> | -s<float>  | 0.75                | How hard to try to match the prompt to the initial image. Ranges from 0.0-0.99, with higher values replacing the initial image completely.|
+
+### This is an example of inpainting:
+
+~~~~
+dream> waterfall and rainbow -I./vacation-photo.png -M./vacation-mask.png -W640 -H480 --fit
+~~~~
+
+This will do the same thing as img2img, but image alterations will
+only occur within transparent areas defined by the mask file specified
+by -M. You may also supply just a single initial image with the areas
+to overpaint made transparent, but you must be careful not to destroy
+the pixels underneath when you create the transparent areas. See
+[Inpainting](./INPAINTING.md) for details.
+
+inpainting accepts all the arguments used for txt2img and img2img, as
+well as the --mask (-M) argument:
+
+| Argument           |  Shortcut  |  Default            |  Description |
+|--------------------|------------|---------------------|--------------|
+| --init_mask <path> | -M<path>   | None                |Path to an image the same size as the initial_image, with areas for inpainting made transparent.|
+
+
+# Convenience commands
+
+In addition to the standard image generation arguments, there are a
+series of convenience commands that begin with !:
+
+## !fix
+
+This command runs a post-processor on a previously-generated image. It
+takes a PNG filename or path and applies your choice of the -U, -G, or
+--embiggen switches in order to fix faces or upscale. If you provide a
+filename, the script will look for it in the current output
+directory. Otherwise you can provide a full or partial path to the
+desired file.
+
+Some examples:
+
+Upscale to 4X its original size and fix faces using codeformer:
+~~~
+dream> !fix 0000045.4829112.png -G1 -U4 -ft codeformer
+~~~
+
+Use the GFPGAN algorithm to fix faces, then upscale to 3X using --embiggen:
+
+~~~
+dream> !fix 0000045.4829112.png -G0.8 -ft gfpgan
+>> fixing outputs/img-samples/0000045.4829112.png
+>> retrieved seed 4829112 and prompt "boy enjoying a banana split"
+>> GFPGAN - Restoring Faces for image seed:4829112
+Outputs:
+[1] outputs/img-samples/000017.4829112.gfpgan-00.png: !fix "outputs/img-samples/0000045.4829112.png" -s 50 -S  -W 512 -H 512 -C 7.5 -A k_lms -G 0.8
+
+dream> !fix 000017.4829112.gfpgan-00.png --embiggen 3
+...lots of text...
+Outputs:
+[2] outputs/img-samples/000018.2273800735.embiggen-00.png: !fix "outputs/img-samples/000017.243781548.gfpgan-00.png" -s 50 -S 2273800735 -W 512 -H 512 -C 7.5 -A k_lms --embiggen 3.0 0.75 0.25
+~~~
+
+## !fetch
+
+This command retrieves the generation parameters from a previously
+generated image and either loads them into the command line.  You may
+provide either the name of a file in the current output directory, or
+a full file path.
+
+~~~
+dream> !fetch 0000015.8929913.png
+# the script returns the next line, ready for editing and running:
+dream> a fantastic alien landscape -W 576 -H 512 -s 60 -A plms -C 7.5
+~~~
+
+Note that this command may behave unexpectedly if given a PNG file that
+was not generated by InvokeAI.
+
+## !history
+
+The dream script keeps track of all the commands you issue during a
+session, allowing you to re-run them. On Mac and Linux systems, it
+also writes the command-line history out to disk, giving you access to
+the most recent 1000 commands issued.
+
+The `!history` command will return a numbered list of all the commands
+issued during the session (Windows), or the most recent 1000 commands
+(Mac|Linux). You can then repeat a command by using the command !NNN,
+where "NNN" is the history line number. For example:
+
+~~~
+dream> !history
+...
+[14] happy woman sitting under tree wearing broad hat and flowing garment
+[15] beautiful woman sitting under tree wearing broad hat and flowing garment
+[18] beautiful woman sitting under tree wearing broad hat and flowing garment -v0.2 -n6
+[20] watercolor of beautiful woman sitting under tree wearing broad hat and flowing garment -v0.2 -n6 -S2878767194
+[21] surrealist painting of beautiful woman sitting under tree wearing broad hat and flowing garment -v0.2 -n6 -S2878767194
+...
+dream> !20
+dream> watercolor of beautiful woman sitting under tree wearing broad hat and flowing garment -v0.2 -n6 -S2878767194
+~~~
+
+## !search <search string>
+
+This is similar to !history but it only returns lines that contain
+`search string`. For example:
+
+~~~
+dream> !search surreal
+[21] surrealist painting of beautiful woman sitting under tree wearing broad hat and flowing garment -v0.2 -n6 -S2878767194
+~~~
+
+## !clear
+
+This clears the search history from memory and disk. Be advised that
+this operation is irreversible and does not issue any warnings!
+
+# Command-line editing and completion
+
+The command-line offers convenient history tracking, editing, and
+command completion.
+
+- To scroll through previous commands and potentially edit/reuse them, use the up and down cursor keys.
+- To edit the current command, use the left and right cursor keys to position the cursor, and then backspace, delete or insert characters.
+- To move to the very beginning of the command, type CTRL-A (or command-A on the Mac)
+- To move to the end of the command, type CTRL-E.
+- To cut a section of the command, position the cursor where you want to start cutting and type CTRL-K.
+- To paste a cut section back in, position the cursor where you want to paste, and type CTRL-Y
+
+Windows users can get similar, but more limited, functionality if they
+launch dream.py with the "winpty" program and have the `pyreadline3`
+library installed:
+
+~~~
+> winpty python scripts\dream.py
+~~~
+
+On the Mac and Linux platforms, when you exit dream.py, the last 1000
+lines of your command-line history will be saved. When you restart
+dream.py, you can access the saved history using the up-arrow key.
+
+In addition, limited command-line completion is installed. In various
+contexts, you can start typing your command and press tab. A list of
+potential completions will be presented to you. You can then type a
+little more, hit tab again, and eventually autocomplete what you want.
+
+When specifying file paths using the one-letter shortcuts, the CLI
+will attempt to complete pathnames for you. This is most handy for the
+-I (init image) and -M (init mask) paths. To initiate completion, start
+the path with a slash ("/") or "./". For example:
+
+~~~
+dream> zebra with a mustache -I./test-pictures<TAB>
+-I./test-pictures/Lincoln-and-Parrot.png  -I./test-pictures/zebra.jpg        -I./test-pictures/madonna.png
+-I./test-pictures/bad-sketch.png          -I./test-pictures/man_with_eagle/
+```
+
+You can then type ++z++, hit ++tab++ again, and it will autofill to `zebra.jpg`.
+
+More text completion features (such as autocompleting seeds) are on their way.

+# :material-loupe: Embiggen
+
+**upscale your images on limited memory machines**
+
+GFPGAN and Real-ESRGAN are both memory intensive. In order to avoid
+crashes and memory overloads during the Stable Diffusion process,
+these effects are applied after Stable Diffusion has completed its
+work.
+
+In single image generations, you will see the output right away but
+when you are using multiple iterations, the images will first be
+generated and then upscaled and face restored after that process is
+complete. While the image generation is taking place, you will still
+be able to preview the base images.
+
+If you wish to stop during the image generation but want to upscale or
+face restore a particular generated image, pass it again with the same
+prompt and generated seed along with the `-U` and `-G` prompt
+arguments to perform those actions.
+
+## Embiggen
+
+If you wanted to be able to do more (pixels) without running out of VRAM,
+or you want to upscale with details that couldn't possibly appear
+without the context of a prompt, this is the feature to try out.
+
+Embiggen automates the process of taking an init image, upscaling it,
+cutting it into smaller tiles that slightly overlap, running all the
+tiles through img2img to refine details with respect to the prompt,
+and "stitching" the tiles back together into a cohesive image.
+
+It automatically computes how many tiles are needed, and so it can be fed
+*ANY* size init image and perform Img2Img on it (though it will be run only
+one tile at a time, which can cause problems, see the Note at the end).
+
+If you're familiar with "GoBig" (ala [progrock-stable](https://github.com/lowfuel/progrock-stable))
+it's similar to that, except it can work up to an arbitrarily large size
+(instead of just 2x), with tile overlaps configurable as a ratio, and
+has extra logic to re-run any number of the tile sub-sections of the image
+if for example a small part of a huge run got messed up.
+
+## Usage
+
+`-embiggen <scaling_factor> <esrgan_strength> <overlap_ratio OR overlap_pixels>`
+
+Takes a scaling factor relative to the size of the `--init_img` (`-I`), followed by
+ESRGAN upscaling strength (0 - 1.0), followed by minimum amount of overlap
+between tiles as a decimal ratio (0 - 1.0) *OR* a number of pixels.
+
+The scaling factor is how much larger than the `--init_img` the output
+should be, and will multiply both x and y axis, so an image that is a
+scaling factor of 3.0 has 3*3= 9 times as many pixels, and will take
+(at least) 9 times as long (see overlap for why it might be
+longer). If the `--init_img` is already the right size `-embiggen 1`,
+and it can also be less than one if the init_img is too big.
+
+Esrgan_strength defaults to 0.75, and the overlap_ratio defaults to
+0.25, both are optional.
+
+Unlike Img2Img, the `--width` (`-W`) and `--height` (`-H`) arguments
+do not control the size of the image as a whole, but the size of the
+tiles used to Embiggen the image.
+
+ESRGAN is used to upscale the `--init_img` prior to cutting it into
+tiles/pieces to run through img2img and then stitch back
+together. Embiggen can be run without ESRGAN; just set the strength to
+zero (e.g. `-embiggen 1.75 0`). The output of Embiggen can also be
+upscaled after it's finished (`-U`).
+
+The overlap is the minimum that tiles will overlap with adjacent
+tiles, specified as either a ratio or a number of pixels. How much the
+tiles overlap determines the likelihood the tiling will be noticable,
+really small overlaps (e.g. a couple of pixels) may produce noticeable
+grid-like fuzzy distortions in the final stitched image. Though, as
+the overlapping space doesn't contribute to making the image bigger,
+and the larger the overlap the more tiles (and the more time) it will
+take to finish.
+
+Because the overlapping parts of tiles don't "contribute" to
+increasing size, every tile after the first in a row or column
+effectively only covers an extra `1 - overlap_ratio` on each axis. If
+the input/`--init_img` is same size as a tile, the ideal (for time)
+scaling factors with the default overlap (0.25) are 1.75, 2.5, 3.25,
+4.0 etc..
+
+`-embiggen_tiles <spaced list of tiles>`
+
+An advanced usage useful if you only want to alter parts of the image
+while running Embiggen. It takes a list of tiles by number to run and
+replace onto the initial image e.g. `1 3 5`. It's useful for either
+fixing problem spots from a previous Embiggen run, or selectively
+altering the prompt for sections of an image - for creative or
+coherency reasons.
+
+Tiles are numbered starting with one, and left-to-right,
+top-to-bottom.  So, if you are generating a 3x3 tiled image, the
+middle row would be `4 5 6`.
+
+## Example Usage
+
+Running Embiggen with 512x512 tiles on an existing image, scaling up by a factor of 2.5x;
+and doing the same again (default ESRGAN strength is 0.75, default overlap between tiles is 0.25):
+
+```bash
+dream > a photo of a forest at sunset -s 100 -W 512 -H 512 -I outputs/forest.png -f 0.4 -embiggen 2.5
+dream > a photo of a forest at sunset -s 100 -W 512 -H 512 -I outputs/forest.png -f 0.4 -embiggen 2.5 0.75 0.25
+```
+
+If your starting image was also 512x512 this should have taken 9 tiles.
+
+If there weren't enough clouds in the sky of that forest you just made
+(and that image is about 1280 pixels (512*2.5) wide A.K.A. three
+512x512 tiles with 0.25 overlaps wide) we can replace that top row of
+tiles:
+
+```bash
+dream> a photo of puffy clouds over a forest at sunset -s 100 -W 512 -H 512 -I outputs/000002.seed.png -f 0.5 -embiggen_tiles 1 2 3
+```
+
+## Fixing Previously-Generated Images
+
+It is easy to apply embiggen to any previously-generated file without having to
+look up the original prompt and provide an initial image. Just use the
+syntax `!fix path/to/file.png <embiggen>`. For example, you can rewrite the
+previous command to look like this:
+
+~~~~
+dream> !fix ./outputs/000002.seed.png -embiggen_tiles 1 2 3
+~~~~
+
+A new file named `000002.seed.fixed.png` will be created in the output directory. Note that
+the `!fix` command does not replace the original file, unlike the behavior at generate time.
+You do not need to provide the prompt, and `!fix` automatically selects a good strength for
+embiggen-ing.
+
+
+**Note**
+Because the same prompt is used on all the tiled images, and the model
+doesn't have the context of anything outside the tile being run - it
+can end up creating repeated pattern (also called 'motifs') across all
+the tiles based on that prompt. The best way to combat this is
+lowering the `--strength` (`-f`) to stay more true to the init image,
+and increasing the number of steps so there is more compute-time to
+create the detail.  Anecdotally `--strength` 0.35-0.45 works pretty
+well on most things. It may also work great in some examples even with
+the `--strength` set high for patterns, landscapes, or subjects that
+are more abstract. Because this is (relatively) fast, you can also
+preserve the best parts from each.

+# :material-image-multiple: **IMG2IMG**
+
+This script also provides an `img2img` feature that lets you seed your creations with an initial
+drawing or photo. This is a really cool feature that tells stable diffusion to build the prompt on
+top of the image you provide, preserving the original's basic shape and layout. To use it, provide
+the `--init_img` option as shown here:
+
+```bash
+dream> "waterfall and rainbow" --init_img=./init-images/crude_drawing.png --strength=0.5 -s100 -n4
+```
+
+The `--init_img (-I)` option gives the path to the seed picture. `--strength (-f)` controls how much
+the original will be modified, ranging from `0.0` (keep the original intact), to `1.0` (ignore the
+original completely). The default is `0.75`, and ranges from `0.25-0.75` give interesting results.
+
+You may also pass a `-v<variation_amount>` option to generate `-n<iterations>` count variants on
+the original image. This is done by passing the first generated image
+back into img2img the requested number of times. It generates
+interesting variants.
+
+If the initial image contains transparent regions, then Stable Diffusion will only draw within the
+transparent regions, a process called "inpainting". However, for this to work correctly, the color
+information underneath the transparent needs to be preserved, not erased.

+## **Creating Transparent Regions for Inpainting**
+
+Inpainting is really cool. To do it, you start with an initial image and use a photoeditor to make
+one or more regions transparent (i.e. they have a "hole" in them). You then provide the path to this
+image at the dream> command line using the `-I` switch. Stable Diffusion will only paint within the
+transparent region.
+
+There's a catch. In the current implementation, you have to prepare the initial image correctly so
+that the underlying colors are preserved under the transparent area. Many imaging editing
+applications will by default erase the color information under the transparent pixels and replace
+them with white or black, which will lead to suboptimal inpainting. You also must take care to
+export the PNG file in such a way that the color information is preserved.
+
+If your photoeditor is erasing the underlying color information, `dream.py` will give you a big fat
+warning. If you can't find a way to coax your photoeditor to retain color values under transparent
+areas, then you can combine the `-I` and `-M` switches to provide both the original unedited image
+and the masked (partially transparent) image:
+
+```bash
+dream> "man with cat on shoulder" -I./images/man.png -M./images/man-transparent.png
+```
+
+We are hoping to get rid of the need for this workaround in an upcoming release.

+
+1. Open image in GIMP.
+2. Layer->Transparency->Add Alpha Channel
+3. Use lasoo tool to select region to mask
+4. Choose Select -> Float to create a floating selection
+5. Open the Layers toolbar (++ctrl+l++) and select "Floating Selection"
+6. Set opacity to 0%
+7. Export as PNG
+8. In the export dialogue, Make sure the "Save colour values from
+   transparent pixels" checkbox is selected.

+
+2. Use any of the selection tools (Marquee, Lasso, or Wand) to select the area you desire to inpaint.
+
+![step2](../assets/step2.png)
+
+3. Because we'll be applying a mask over the area we want to preserve, you should now select the inverse by using the ++shift+ctrl+i++ shortcut, or right clicking and using the "Select Inverse" option.
+
+4. You'll now create a mask by selecting the image layer, and Masking the selection. Make sure that you don't delete any of the undrlying image, or your inpainting results will be dramatically impacted.
+
+![step4](../assets/step4.png)
+
+5. Make sure to hide any background layers that are present. You should see the mask applied to your image layer, and the image on your canvas should display the checkered background.
+
+![step5](../assets/step5.png)
+
+6. Save the image as a transparent PNG by using the "Save a Copy" option in the File menu, or using the Alt + Ctrl + S keyboard shortcut
+
+![step6](../assets/step6.png)
+
+7. After following the inpainting instructions above (either through the CLI or the Web UI), marvel at your newfound ability to selectively dream. Lookin' good!

+Output Example: ![Colab Notebook](../assets/colab_notebook.png)
+

+
+## **Seamless Tiling**
+
+The seamless tiling mode causes generated images to seamlessly tile with itself. To use it, add the
+`--seamless` option when starting the script which will result in all generated images to tile, or
+for each `dream>` prompt as shown here:
+
+```python
+dream> "pond garden with lotus by claude monet" --seamless -s100 -n4
+```
+
+---
+
+## **Shortcuts: Reusing Seeds**
+
+Since it is so common to reuse seeds while refining a prompt, there is now a shortcut as of version
+1.11. Provide a `**-S**` (or `**--seed**`) switch of `-1` to use the seed of the most recent image
+generated. If you produced multiple images with the `**-n**` switch, then you can go back further
+using -2, -3, etc. up to the first image generated by the previous command. Sorry, but you can't go
+back further than one command.
+
+Here's an example of using this to do a quick refinement. It also illustrates using the new `**-G**`
+switch to turn on upscaling and face enhancement (see previous section):
+
+```bash
+dream> a cute child playing hopscotch -G0.5
+[...]
+outputs/img-samples/000039.3498014304.png: "a cute child playing hopscotch" -s50 -W512 -H512 -C7.5 -mk_lms -S3498014304
+
+# I wonder what it will look like if I bump up the steps and set facial enhancement to full strength?
+dream> a cute child playing hopscotch -G1.0 -s100 -S -1
+reusing previous seed 3498014304
+[...]
+outputs/img-samples/000040.3498014304.png: "a cute child playing hopscotch" -G1.0 -s100 -W512 -H512 -C7.5 -mk_lms -S3498014304
+```
+
+---
+
+## **Weighted Prompts**
+
+You may weight different sections of the prompt to tell the sampler to attach different levels of
+priority to them, by adding `:(number)` to the end of the section you wish to up- or downweight. For
+example consider this prompt:
+
+```bash
+tabby cat:0.25 white duck:0.75 hybrid
+```
+
+This will tell the sampler to invest 25% of its effort on the tabby cat aspect of the image and 75%
+on the white duck aspect (surprisingly, this example actually works). The prompt weights can use any
+combination of integers and floating point numbers, and they do not need to add up to 1.
+
+---
+
+## Thresholding and Perlin Noise Initialization Options
+
+Two new options are the thresholding (`--threshold`) and the perlin noise initialization (`--perlin`) options. Thresholding limits the range of the latent values during optimization, which helps combat oversaturation with higher CFG scale values. Perlin noise initialization starts with a percentage (a value ranging from 0 to 1) of perlin noise mixed into the initial noise. Both features allow for more variations and options in the course of generating images.
+
+For better intuition into what these options do in practice, [here is a graphic demonstrating them both](static/truncation_comparison.jpg) in use. In generating this graphic, perlin noise at initialization was programmatically varied going across on the diagram by values 0.0, 0.1, 0.2, 0.4, 0.5, 0.6, 0.8, 0.9, 1.0; and the threshold was varied going down from
+0, 1, 2, 3, 4, 5, 10, 20, 100. The other options are fixed, so the initial prompt is as follows (no thresholding or perlin noise):
+
+```
+    a portrait of a beautiful young lady -S 1950357039 -s 100 -C 20 -A k_euler_a --threshold 0 --perlin 0
+```
+
+Here's an example of another prompt used when setting the threshold to 5 and perlin noise to 0.2:
+
+```
+    a portrait of a beautiful young lady -S 1950357039 -s 100 -C 20 -A k_euler_a --threshold 5 --perlin 0.2
+```
+
+Note: currently the thresholding feature is only implemented for the k-diffusion style samplers, and empirically appears to work best with `k_euler_a` and `k_dpm_2_a`. Using 0 disables thresholding. Using 0 for perlin noise disables using perlin noise for initialization. Finally, using 1 for perlin noise uses only perlin noise for initialization.
+
+---
+
+## **Simplified API**
+
+For programmers who wish to incorporate stable-diffusion into other products, this repository
+includes a simplified API for text to image generation, which lets you create images from a prompt
+in just three lines of code:
+
+```bash
+from ldm.generate import Generate
+g       = Generate()
+outputs = g.txt2img("a unicorn in manhattan")
+```
+
+Outputs is a list of lists in the format [filename1,seed1],[filename2,seed2]...].
+
+Please see ldm/generate.py for more information. A set of example scripts is coming RSN.
+
+---
+
+## **Preload Models**
+
+In situations where you have limited internet connectivity or are blocked behind a firewall, you can
+use the preload script to preload the required files for Stable Diffusion to run.
+
+The preload script `scripts/preload_models.py` needs to be run once at least while connected to the
+internet. In the following runs, it will load up the cached versions of the required files from the
+`.cache` directory of the system.
+
+```bash

+# :octicons-paintbrush-16: Outpainting
+
+## Outpainting and outcropping
+
+Outpainting is a process by which the AI generates parts of the image
+that are outside its original frame. It can be used to fix up images
+in which the subject is off center, or when some detail (often the top
+of someone's head!) is cut off.
+
+InvokeAI supports two versions of outpainting, one called "outpaint"
+and the other "outcrop." They work slightly differently and each has
+its advantages and drawbacks.
+
+### Outcrop
+
+The `outcrop` extension allows you to extend the image in 64 pixel
+increments in any dimension. You can apply the module to any image
+previously-generated by InvokeAI. Note that it will **not** work with
+arbitrary photographs or Stable Diffusion images created by other
+implementations.
+
+Consider this image:
+
+![curly_woman](../assets/outpainting/curly.png)
+
+Pretty nice, but it's annoying that the top of her head is cut
+off. She's also a bit off center. Let's fix that!
+
+~~~~
+dream> !fix images/curly.png --outcrop top 64 right 64
+~~~~
+
+This is saying to apply the `outcrop` extension by extending the top
+of the image by 64 pixels, and the right of the image by the same
+amount. You can use any combination of top|left|right|bottom, and
+specify any number of pixels to extend. You can also abbreviate
+`--outcrop` to `-c`.
+
+The result looks like this:
+
+![curly_woman_outcrop](../assets/outpainting/curly-outcrop.png)
+
+The new image is actually slightly larger than the original (576x576,
+because 64 pixels were added to the top and right sides.)
+
+A number of caveats:
+
+1. Although you can specify any pixel values, they will be rounded up
+to the nearest multiple of 64. Smaller values are better. Larger
+extensions are more likely to generate artefacts. However, if you wish
+you can run the !fix command repeatedly to cautiously expand the
+image.
+
+2. The extension is stochastic, meaning that each time you run it
+you'll get a slightly different result. You can run it repeatedly
+until you get an image you like. Unfortunately `!fix` does not
+currently respect the `-n` (`--iterations`) argument.
+
+## Outpaint
+
+The `outpaint` extension does the same thing, but with subtle
+differences. Starting with the same image, here is how we would add an
+additional 64 pixels to the top of the image:
+
+~~~
+dream> !fix images/curly.png --out_direction top 64
+~~~
+
+(you can abbreviate ``--out_direction` as `-D`.
+
+The result is shown here:
+
+![curly_woman_outpaint](../assets/outpainting/curly-outpaint.png)
+
+Although the effect is similar, there are significant differences from
+outcropping:
+
+1. You can only specify one direction to extend at a time.
+2. The image is **not** resized. Instead, the image is shifted by the specified
+number of pixels. If you look carefully, you'll see that less of the lady's
+torso is visible in the image.
+3. Because the image dimensions remain the same, there's no rounding
+to multiples of 64.
+4. Attempting to outpaint larger areas will frequently give rise to ugly
+   ghosting effects.
+5. For best results, try increasing the step number.
+6. If you don't specify a pixel value in -D, it will default to half
+   of the whole image, which is likely not what you want.
+
+Neither `outpaint` nor `outcrop` are perfect, but we continue to tune
+and improve them. If one doesn't work, try the other. You may also
+wish to experiment with other `img2img` arguments, such as `-C`, `-f`
+and `-s`.

+
+## Intro
+
+This extension provides the ability to restore faces and upscale
+images.
+
+Face restoration and upscaling can be applied at the time you generate
+the images, or at any later time against a previously-generated PNG
+file, using the [!fix](#fixing-previously-generated-images)
+command. [Outpainting and outcropping](OUTPAINTING.md) can only be
+applied after the fact.
+
+## Face Fixing
+
+The default face restoration module is GFPGAN. The default upscale is
+Real-ESRGAN. For an alternative face restoration module, see [CodeFormer
+Support] below.
+
+As of version 1.14, environment.yaml will install the Real-ESRGAN package into
+the standard install location for python packages, and will put GFPGAN into a
+subdirectory of "src" in the InvokeAI directory. (The reason for this is
+that the standard GFPGAN distribution has a minor bug that adversely affects
+image color.) Upscaling with Real-ESRGAN should "just work" without further
+intervention. Simply pass the --upscale (-U) option on the dream> command line,
+or indicate the desired scale on the popup in the Web GUI.
+
+For **GFPGAN** to work, there is one additional step needed. You will need to
+download and copy the GFPGAN
+[models file](https://github.com/TencentARC/GFPGAN/releases/download/v1.3.0/GFPGANv1.4.pth)
+into **src/gfpgan/experiments/pretrained_models**. On Mac and Linux systems,
+here's how you'd do it using **wget**:
+
+```bash
+wget https://github.com/TencentARC/GFPGAN/releases/download/v1.3.0/GFPGANv1.4.pth -P src/gfpgan/experiments/pretrained_models/
+```
+
+Make sure that you're in the InvokeAI directory when you do this.
+
+Alternatively, if you have GFPGAN installed elsewhere, or if you are using an
+earlier version of this package which asked you to install GFPGAN in a sibling
+directory, you may use the `--gfpgan_dir` argument with `dream.py` to set a
+custom path to your GFPGAN directory. _There are other GFPGAN related boot
+arguments if you wish to customize further._
+
+!!! warning "Internet connection needed"
+
+    Users whose GPU machines are isolated from the Internet (e.g.
+    on a University cluster) should be aware that the first time you run dream.py with GFPGAN and
+    Real-ESRGAN turned on, it will try to download model files from the Internet. To rectify this, you
+    may run `python3 scripts/preload_models.py` after you have installed GFPGAN and all its
+    dependencies.
+
+## Usage
+
+You will now have access to two new prompt arguments.
+
+### Upscaling
+
+`-U : <upscaling_factor> <upscaling_strength>`
+
+The upscaling prompt argument takes two values. The first value is a scaling
+factor and should be set to either `2` or `4` only. This will either scale the
+image 2x or 4x respectively using different models.
+
+You can set the scaling stength between `0` and `1.0` to control intensity of
+the of the scaling. This is handy because AI upscalers generally tend to smooth
+out texture details. If you wish to retain some of those for natural looking
+results, we recommend using values between `0.5 to 0.8`.
+
+If you do not explicitly specify an upscaling_strength, it will default to 0.75.
+
+### Face Restoration
+
+`-G : <gfpgan_strength>`
+
+This prompt argument controls the strength of the face restoration that is being
+applied. Similar to upscaling, values between `0.5 to 0.8` are recommended.
+
+You can use either one or both without any conflicts. In cases where you use
+both, the image will be first upscaled and then the face restoration process
+will be executed to ensure you get the highest quality facial features.
+
+`--save_orig`
+
+When you use either `-U` or `-G`, the final result you get is upscaled or face
+modified. If you want to save the original Stable Diffusion generation, you can
+use the `-save_orig` prompt argument to save the original unaffected version
+too.
+
+### Example Usage
+
+```bash
+dream> superman dancing with a panda bear -U 2 0.6 -G 0.4
+```
+
+This also works with img2img:
+
+```bash
+dream> a man wearing a pineapple hat -I path/to/your/file.png -U 2 0.5 -G 0.6
+```
+
+!!! note
+
+    GFPGAN and Real-ESRGAN are both memory intensive. In order to avoid crashes and memory overloads
+    during the Stable Diffusion process, these effects are applied after Stable Diffusion has completed
+    its work.
+
+    In single image generations, you will see the output right away but when you are using multiple
+    iterations, the images will first be generated and then upscaled and face restored after that
+    process is complete. While the image generation is taking place, you will still be able to preview
+    the base images.
+
+If you wish to stop during the image generation but want to upscale or face
+restore a particular generated image, pass it again with the same prompt and
+generated seed along with the `-U` and `-G` prompt arguments to perform those
+actions.
+
+## CodeFormer Support
+
+This repo also allows you to perform face restoration using
+[CodeFormer](https://github.com/sczhou/CodeFormer).
+
+In order to setup CodeFormer to work, you need to download the models like with
+GFPGAN. You can do this either by running `preload_models.py` or by manually
+downloading the
+[model file](https://github.com/sczhou/CodeFormer/releases/download/v0.1.0/codeformer.pth)
+and saving it to `ldm/restoration/codeformer/weights` folder.
+
+You can use `-ft` prompt argument to swap between CodeFormer and the default
+GFPGAN. The above mentioned `-G` prompt argument will allow you to control the
+strength of the restoration effect.
+
+### Usage:
+
+The following command will perform face restoration with CodeFormer instead of
+the default gfpgan.
+
+`<prompt> -G 0.8 -ft codeformer`
+
+### Other Options:
+
+- `-cf` - cf or CodeFormer Fidelity takes values between `0` and `1`. 0 produces
+  high quality results but low accuracy and 1 produces lower quality results but
+  higher accuacy to your original face.
+
+The following command will perform face restoration with CodeFormer. CodeFormer
+will output a result that is closely matching to the input face.
+
+`<prompt> -G 1.0 -ft codeformer -cf 0.9`
+
+The following command will perform face restoration with CodeFormer. CodeFormer
+will output a result that is the best restoration possible. This may deviate
+slightly from the original face. This is an excellent option to use in
+situations when there is very little facial data to work with.
+
+`<prompt> -G 1.0 -ft codeformer -cf 0.1`
+
+## Fixing Previously-Generated Images
+
+It is easy to apply face restoration and/or upscaling to any
+previously-generated file. Just use the syntax `!fix path/to/file.png
+<options>`. For example, to apply GFPGAN at strength 0.8 and upscale
+2X for a file named `./outputs/img-samples/000044.2945021133.png`,
+just run:
+
+```
+dream> !fix ./outputs/img-samples/000044.2945021133.png -G 0.8 -U 2
+```
+
+A new file named `000044.2945021133.fixed.png` will be created in the output
+directory. Note that the `!fix` command does not replace the original file,
+unlike the behavior at generate time.
+
+### Disabling:
+
+If, for some reason, you do not wish to load the GFPGAN and/or ESRGAN libraries,
+you can disable them on the dream.py command line with the `--no_restore` and
+`--no_upscale` options, respectively.

+# :octicons-command-palette-24: Prompting Features
+
+## **Reading Prompts from a File**
+
+You can automate `dream.py` by providing a text file with the prompts you want to run, one line per
+prompt. The text file must be composed with a text editor (e.g. Notepad) and not a word processor.
+Each line should look like what you would type at the dream> prompt:
+
+```bash
+a beautiful sunny day in the park, children playing -n4 -C10
+stormy weather on a mountain top, goats grazing     -s100
+innovative packaging for a squid's dinner           -S137038382
+```
+
+Then pass this file's name to `dream.py` when you invoke it:
+
+```bash
+(ldm) ~/stable-diffusion$ python3 scripts/dream.py --from_file "path/to/prompts.txt"
+```
+
+You may read a series of prompts from standard input by providing a filename of `-`:
+
+```bash
+(ldm) ~/stable-diffusion$ echo "a beautiful day" | python3 scripts/dream.py --from_file -
+```
+
+---
+
+## **Weighted Prompts**
+
+You may weight different sections of the prompt to tell the sampler to attach different levels of
+priority to them, by adding `:(number)` to the end of the section you wish to up- or downweight. For
+example consider this prompt:
+
+```bash
+tabby cat:0.25 white duck:0.75 hybrid
+```
+
+This will tell the sampler to invest 25% of its effort on the tabby cat aspect of the image and 75%
+on the white duck aspect (surprisingly, this example actually works). The prompt weights can use any
+combination of integers and floating point numbers, and they do not need to add up to 1.
+
+---
+
+## **Negative and Unconditioned Prompts**
+
+Any words between a pair of square brackets will try and be ignored by Stable Diffusion's model during generation of images.
+
+```bash
+this is a test prompt [not really] to make you understand [cool] how this works.
+```
+
+In the above statement, the words 'not really cool` will be ignored by Stable Diffusion.
+
+Here's a prompt that depicts what it does.
+
+original prompt:
+
+`#!bash "A fantastical translucent poney made of water and foam, ethereal, radiant, hyperalism, scottish folklore, digital painting, artstation, concept art, smooth, 8 k frostbite 3 engine, ultra detailed, art by artgerm and greg rutkowski and magali villeneuve" -s 20 -W 512 -H 768 -C 7.5 -A k_euler_a -S 1654590180`
+
+![step1](../assets/negative_prompt_walkthru/step1.png)
+
+That image has a woman, so if we want the horse without a rider, we can influence the image not to have a woman by putting [woman] in the prompt, like this:
+
+`#!bash "A fantastical translucent poney made of water and foam, ethereal, radiant, hyperalism, scottish folklore, digital painting, artstation, concept art, smooth, 8 k frostbite 3 engine, ultra detailed, art by artgerm and greg rutkowski and magali villeneuve [woman]" -s 20 -W 512 -H 768 -C 7.5 -A k_euler_a -S 1654590180`
+
+![step2](../assets/negative_prompt_walkthru/step2.png)
+
+That's nice - but say we also don't want the image to be quite so blue. We can add "blue" to the list of negative prompts, so it's now [woman blue]:
+
+`#!bash "A fantastical translucent poney made of water and foam, ethereal, radiant, hyperalism, scottish folklore, digital painting, artstation, concept art, smooth, 8 k frostbite 3 engine, ultra detailed, art by artgerm and greg rutkowski and magali villeneuve [woman blue]" -s 20 -W 512 -H 768 -C 7.5 -A k_euler_a -S 1654590180`
+
+![step3](../assets/negative_prompt_walkthru/step3.png)
+
+Getting close - but there's no sense in having a saddle when our horse doesn't have a rider, so we'll add one more negative prompt: [woman blue saddle].
+
+`#!bash "A fantastical translucent poney made of water and foam, ethereal, radiant, hyperalism, scottish folklore, digital painting, artstation, concept art, smooth, 8 k frostbite 3 engine, ultra detailed, art by artgerm and greg rutkowski and magali villeneuve [woman blue saddle]" -s 20 -W 512 -H 768 -C 7.5 -A k_euler_a -S 1654590180`
+
+![step4](../assets/negative_prompt_walkthru/step4.png)
+
+!!! notes "Notes about this feature:"
+
+    * The only requirement for words to be ignored is that they are in between a pair of square brackets.
+    * You can provide multiple words within the same bracket.
+    * You can provide multiple brackets with multiple words in different places of your prompt. That works just fine.
+    * To improve typical anatomy problems, you can add negative prompts like `[bad anatomy, extra legs, extra arms, extra fingers, poorly drawn hands, poorly drawn feet, disfigured, out of frame, tiling, bad art, deformed, mutated]`.

+## **Personalizing Text-to-Image Generation**
+
+You may personalize the generated images to provide your own styles or objects
+by training a new LDM checkpoint and introducing a new vocabulary to the fixed
+model as a (.pt) embeddings file. Alternatively, you may use or train
+HuggingFace Concepts embeddings files (.bin) from
+<https://huggingface.co/sd-concepts-library> and its associated notebooks.
+
+## **Training**
+
+To train, prepare a folder that contains images sized at 512x512 and execute the
+following:
+
+### WINDOWS
+
+As the default backend is not available on Windows, if you're using that
+platform, set the environment variable `PL_TORCH_DISTRIBUTED_BACKEND` to `gloo`
+
+```bash
+python3 ./main.py --base ./configs/stable-diffusion/v1-finetune.yaml \
+                  --actual_resume ./models/ldm/stable-diffusion-v1/model.ckpt \
+                  -t \
+                  -n my_cat \
+                  --gpus 0 \
+                  --data_root D:/textual-inversion/my_cat \
+                  --init_word 'cat'
+```
+
+During the training process, files will be created in
+`/logs/[project][time][project]/` where you can see the process.
+
+Conditioning contains the training prompts inputs, reconstruction the input
+images for the training epoch samples, samples scaled for a sample of the prompt
+and one with the init word provided.
+
+On a RTX3090, the process for SD will take ~1h @1.6 iterations/sec.
+
+!!! note
+
+    According to the associated paper, the optimal number of
+    images is 3-5. Your model may not converge if you use more images than
+    that.
+
+Training will run indefinitely, but you may wish to stop it (with ctrl-c) before
+the heat death of the universe, when you find a low loss epoch or around ~5000
+iterations. Note that you can set a fixed limit on the number of training steps
+by decreasing the "max_steps" option in
+configs/stable_diffusion/v1-finetune.yaml (currently set to 4000000)
+
+## **Run the Model**
+
+Once the model is trained, specify the trained .pt or .bin file when starting
+dream using
+
+```bash
+python3 ./scripts/dream.py --embedding_path /path/to/embedding.pt
+```
+
+Then, to utilize your subject at the dream prompt
+
+```bash
+dream> "a photo of *"
+```
+
+This also works with image2image
+
+```bash
+dream> "waterfall and rainbow in the style of *" --init_img=./init-images/crude_drawing.png --strength=0.5 -s100 -n4
+```
+
+For .pt files it's also possible to train multiple tokens (modify the
+placeholder string in `configs/stable-diffusion/v1-finetune.yaml`) and combine
+LDM checkpoints using:
+
+```bash
+python3 ./scripts/merge_embeddings.py \

+title: Variations

+
+# :material-tune-variant: Variations
+
+## Intro
+
+Release 1.13 of SD-Dream adds support for image variations.
+
+You are able to do the following:
+
+1. Generate a series of systematic variations of an image, given a prompt. The
+   amount of variation from one image to the next can be controlled.
+
+2. Given two or more variations that you like, you can combine them in a
+   weighted fashion.
+
+---
+
+This cheat sheet provides a quick guide for how this works in practice, using
+variations to create the desired image of Xena, Warrior Princess.
+
+---
+
+## Step 1 -- Find a base image that you like
+
+The prompt we will use throughout is
+`lucy lawless as xena, warrior princess, character portrait, high resolution.`
+
+This will be indicated as `prompt` in the examples below.
+
+First we let SD create a series of images in the usual way, in this case
+requesting six iterations:
+
+```bash
+dream> lucy lawless as xena, warrior princess, character portrait, high resolution -n6
+...
+Outputs:
+./outputs/Xena/000001.1579445059.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -S1579445059
+./outputs/Xena/000001.1880768722.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -S1880768722
+./outputs/Xena/000001.332057179.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -S332057179
+./outputs/Xena/000001.2224800325.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -S2224800325
+./outputs/Xena/000001.465250761.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -S465250761
+./outputs/Xena/000001.3357757885.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -S3357757885
+```
+
+![var1](../assets/variation_walkthru/000001.3357757885.png)
+
+---
+
+## Step 2 - Generating Variations
+
+Let's try to generate some variations. Using the same seed, we pass the argument
+`-v0.1` (or --variant_amount), which generates a series of variations each
+differing by a variation amount of 0.2. This number ranges from `0` to `1.0`,
+with higher numbers being larger amounts of variation.
+
+```bash
+dream> "prompt" -n6 -S3357757885 -v0.2
+...
+Outputs:
+./outputs/Xena/000002.784039624.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -V 784039624:0.2 -S3357757885
+./outputs/Xena/000002.3647897225.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -V 3647897225:0.2 -S3357757885
+./outputs/Xena/000002.917731034.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -V 917731034:0.2 -S3357757885
+./outputs/Xena/000002.4116285959.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -V 4116285959:0.2 -S3357757885
+./outputs/Xena/000002.1614299449.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -V 1614299449:0.2 -S3357757885
+./outputs/Xena/000002.1335553075.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -V 1335553075:0.2 -S3357757885
+```
+
+### **Variation Sub Seeding**
+
+Note that the output for each image has a `-V` option giving the "variant
+subseed" for that image, consisting of a seed followed by the variation amount
+used to generate it.
+
+This gives us a series of closely-related variations, including the two shown
+here.
+
+![var2](../assets/variation_walkthru/000002.3647897225.png)
+
+![var3](../assets/variation_walkthru/000002.1614299449.png)
+
+I like the expression on Xena's face in the first one (subseed 3647897225), and
+the armor on her shoulder in the second one (subseed 1614299449). Can we combine
+them to get the best of both worlds?
+
+We combine the two variations using `-V` (`--with_variations`). Again, we must
+provide the seed for the originally-chosen image in order for this to work.
+
+```bash
+dream> "prompt"  -S3357757885 -V3647897225,0.1,1614299449,0.1
+Outputs:
+./outputs/Xena/000003.1614299449.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -V 3647897225:0.1,1614299449:0.1 -S3357757885
+```
+
+Here we are providing equal weights (0.1 and 0.1) for both the subseeds. The
+resulting image is close, but not exactly what I wanted:
+
+![var4](../assets/variation_walkthru/000003.1614299449.png)
+
+We could either try combining the images with different weights, or we can
+generate more variations around the almost-but-not-quite image. We do the
+latter, using both the `-V` (combining) and `-v` (variation strength) options.
+Note that we use `-n6` to generate 6 variations:
+
+```bash
+dream> "prompt" -S3357757885 -V3647897225,0.1,1614299449,0.1 -v0.05 -n6
+Outputs:
+./outputs/Xena/000004.3279757577.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -V 3647897225:0.1,1614299449:0.1,3279757577:0.05 -S3357757885

+./outputs/Xena/000004.2664260391.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -V 3647897225:0.1,1614299449:0.1,2664260391:0.05 -S3357757885
+./outputs/Xena/000004.1642517170.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -V 3647897225:0.1,1614299449:0.1,1642517170:0.05 -S3357757885
+./outputs/Xena/000004.2183375608.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -V 3647897225:0.1,1614299449:0.1,2183375608:0.05 -S3357757885
+```
+
+This produces six images, all slight variations on the combination of the chosen
+two images. Here's the one I like best:
+
+![var5](../assets/variation_walkthru/000004.3747154981.png)
+
+As you can see, this is a very powerful tool, which when combined with subprompt
+weighting, gives you great control over the content and quality of your
+generated images.

+title: SAMPLER CONVERGENCE
+---
+
+## *Sampler Convergence*
+
+As features keep increasing, making the right choices for your needs can become increasingly difficult. What sampler to use? And for how many steps? Do you change the CFG value? Do you use prompt weighting? Do you allow variations?
+
+Even once you have a result, do you blend it with other images? Pass it through `img2img`? With what strength? Do you use inpainting to correct small details? Outpainting to extend cropped sections?
+
+The purpose of this series of documents is to help you better understand these tools, so you can make the best out of them. Feel free to contribute with your own findings!
+
+In this document, we will talk about sampler convergence.
+
+Looking for a short version? Here's a TL;DR in 3 tables.
+
+| Remember  |
+|:---|
+| Results converge as steps (`-s`) are increased (except for `K_DPM_2_A` and `K_EULER_A`). Often at ≥ `-s100`, but may require ≥ `-s700`).  |
+| Producing a batch of candidate images at low (`-s8` to `-s30`) step counts can save you hours of computation.  |
+| `K_HEUN` and `K_DPM_2`  converge in less steps (but are slower).  |
+| `K_DPM_2_A` and `K_EULER_A` incorporate a lot of creativity/variability. |
+
+| Sampler   | (3 sample avg) it/s (M1 Max 64GB, 512x512)  |
+|---|---|
+|  `DDIM` | 1.89  |
+|  `PLMS` | 1.86  |
+|  `K_EULER` | 1.86  |
+|  `K_LMS` | 1.91  |
+|  `K_HEUN` | 0.95 (slower)  |
+|  `K_DPM_2` | 0.95 (slower)  |
+|  `K_DPM_2_A` | 0.95 (slower)  |
+|  `K_EULER_A` | 1.86  |
+
+| Suggestions  |
+|:---|
+| For most use cases, `K_LMS`, `K_HEUN` and `K_DPM_2` are the best choices (the latter 2 run 0.5x as quick, but tend to converge 2x as quick as `K_LMS`). At very low steps (≤ `-s8`), `K_HEUN` and `K_DPM_2` are not recommended. Use `K_LMS` instead.|
+| For variability, use `K_EULER_A` (runs 2x as quick as `K_DPM_2_A`).  |
+
+---
+
+### *Sampler results*
+
+Let's start by choosing a prompt and using it with each of our 8 samplers, running it for 10, 20, 30, 40, 50 and 100 steps.
+
+Anime. `"an anime girl" -W512 -H512 -C7.5 -S3031912972`
+
+![191636411-083c8282-6ed1-4f78-9273-ee87c0a0f1b6-min (1)](https://user-images.githubusercontent.com/50542132/191868725-7f7af991-e254-4c1f-83e7-bed8c9b2d34f.png)
+
+### *Sampler convergence*
+
+Immediately, you can notice results tend to converge -that is, as `-s` (step) values increase, images look more and more similar until there comes a point where the image no longer changes.
+
+You can also notice how `DDIM` and `PLMS` eventually tend to converge to K-sampler results as steps are increased.
+Among K-samplers, `K_HEUN` and `K_DPM_2` seem to require the fewest steps to converge, and even at low step counts they are good indicators of the final result. And finally, `K_DPM_2_A` and `K_EULER_A` seem to do a bit of their own thing and don't keep much similarity with the rest of the samplers.
+
+### *Batch generation speedup*
+
+This realization is very useful because it means you don't need to create a batch of 100 images (`-n100`) at `-s100` to choose your favorite 2 or 3 images.
+You can produce the same 100 images at `-s10` to `-s30` using a K-sampler (since they converge faster), get a rough idea of the final result, choose your 2 or 3 favorite ones, and then run `-s100` on those images to polish some details.
+The latter technique is 3-8x as quick.
+
+Example:
+
+At 60s per 100 steps.
+
+(Option A) 60s * 100 images = 6000s (100 images at `-s100`, manually picking 3 favorites)
+
+(Option B) 6s * 100 images + 60s * 3 images = 780s (100 images at `-s10`, manually picking 3 favorites, and running those 3 at `-s100` to polish details)
+
+The result is 1 hour and 40 minutes (Option A) vs 13 minutes (Option B).
+
+### *Topic convergance*
+
+Now, these results seem interesting, but do they hold for other topics? How about nature? Food? People? Animals? Let's try!
+
+Nature. `"valley landscape wallpaper, d&d art, fantasy, painted, 4k, high detail, sharp focus, washed colors, elaborate excellent painted illustration" -W512 -H512 -C7.5 -S1458228930`
+
+![191736091-dda76929-00d1-4590-bef4-7314ea4ea419-min (1)](https://user-images.githubusercontent.com/50542132/191868763-b151c69e-0a72-4cf1-a151-5a64edd0c93e.png)
+
+With nature, you can see how initial results are even more indicative of final result -more so than with characters/people. `K_HEUN` and `K_DPM_2` are again the quickest indicators, almost right from the start. Results also converge faster (e.g. `K_HEUN` converged at `-s21`).
+
+Food. `"a hamburger with a bowl of french fries" -W512 -H512 -C7.5 -S4053222918`
+
+![191639011-f81d9d38-0a15-45f0-9442-a5e8d5c25f1f-min (1)](https://user-images.githubusercontent.com/50542132/191868898-98801a62-885f-4ea1-aee8-563503522aa9.png)
+
+Again, `K_HEUN` and `K_DPM_2` take the fewest number of steps to be good indicators of the final result. `K_DPM_2_A` and `K_EULER_A` seem to incorporate a lot of creativity/variability, capable of producing rotten hamburgers, but also of adding lettuce to the mix. And they're the only samplers that produced an actual 'bowl of fries'!
+
+Animals. `"grown tiger, full body" -W512 -H512 -C7.5 -S3721629802`
+
+![191771922-6029a4f5-f707-4684-9011-c6f96e25fe56-min (1)](https://user-images.githubusercontent.com/50542132/191868870-9e3b7d82-b909-429f-893a-13f6ec343454.png)
+
+`K_HEUN` and `K_DPM_2` once again require the least number of steps to be indicative of the final result (around `-s30`), while other samplers are still struggling with several tails or malformed back legs.
+
+It also takes longer to converge (for comparison, `K_HEUN` required around 150 steps to converge). This is normal, as producing human/animal faces/bodies is one of the things the model struggles the most with. For these topics, running for more steps will often increase coherence within the composition.
+
+People. `"Ultra realistic photo, (Miranda Bloom-Kerr), young, stunning model, blue eyes, blond hair, beautiful face, intricate, highly detailed, smooth, art by artgerm and greg rutkowski and alphonse mucha, stained glass" -W512 -H512 -C7.5 -S2131956332`. This time, we will go up to 300 steps.
+
+![Screenshot 2022-09-23 at 02 05 48-min (1)](https://user-images.githubusercontent.com/50542132/191871743-6802f199-0ffd-4986-98c5-df2d8db30d18.png)
+
+Observing the results, it again takes longer for all samplers to converge (`K_HEUN` took around 150 steps), but we can observe good indicative results much earlier (see: `K_HEUN`). Conversely, `DDIM` and `PLMS` are still undergoing moderate changes (see: lace around her neck), even at `-s300`.
+
+In fact, as we can see in this other experiment, some samplers can take 700+ steps to converge when generating people.
+
+![191988191-c586b75a-2d7f-4351-b705-83cc1149881a-min (1)](https://user-images.githubusercontent.com/50542132/191992123-7e0759d6-6220-42c4-a961-88c7071c5ee6.png)
+
+Note also the point of convergence may not be the most desirable state (e.g. I prefer an earlier version of the face, more rounded), but it will probably be the most coherent arms/hands/face attributes-wise. You can always merge different images with a photo editing tool and pass it through `img2img` to smoothen the composition.
+
+### *Sampler generation times*
+
+Once we understand the concept of sampler convergence, we must look into the performance of each sampler in terms of steps (iterations) per second, as not all samplers run at the same speed.
+
+On my M1 Max with 64GB of RAM, for a 512x512 image:
+| Sampler   | (3 sample average) it/s |
+|---|---|
+|  `DDIM` | 1.89  |
+|  `PLMS` | 1.86  |
+|  `K_EULER` | 1.86  |
+|  `K_LMS` | 1.91  |
+|  `K_HEUN` | 0.95 (slower)  |
+|  `K_DPM_2` | 0.95 (slower)  |
+|  `K_DPM_2_A` | 0.95 (slower)  |
+|  `K_EULER_A` | 1.86  |
+
+Combining our results with the steps per second of each sampler, three choices come out on top: `K_LMS`, `K_HEUN` and `K_DPM_2` (where the latter two run 0.5x as quick but tend to converge 2x as quick as `K_LMS`). For creativity and a lot of variation between iterations, `K_EULER_A` can be a good choice (which runs 2x as quick as `K_DPM_2_A`).
+
+Additionally, image generation at very low steps (≤ `-s8`) is not recommended for `K_HEUN` and `K_DPM_2`. Use `K_LMS` instead.
+
+<img width="397" alt="192044949-67d5d441-a0d5-4d5a-be30-5dda4fc28a00-min" src="https://user-images.githubusercontent.com/50542132/192046823-2714cb29-bbf3-4eb1-9213-e27a0963905c.png">
+
+### *Three key points*
+
+Finally, it is relevant to mention that, in general, there are 3 important moments in the process of image formation as steps increase:
+
+* The (earliest) point at which an image becomes a good indicator of the final result (useful for batch generation at low step values, to then improve the quality/coherence of the chosen images via running the same prompt and seed for more steps).
+
+* The (earliest) point at which an image becomes coherent, even if different from the result if steps are increased (useful for batch generation at low step values, where quality/coherence is improved via techniques other than increasing the steps -e.g. via inpainting).
+
+* The point at which an image fully converges.
+
+Hence, remember that your workflow/strategy should define your optimal number of steps, even for the same prompt and seed (for example, if you seek full convergence, you may run `K_LMS` for `-s200` in the case of the red-haired girl, but `K_LMS` and `-s20`-taking one tenth the time- may do as well if your workflow includes adding small details, such as the missing shoulder strap, via `img2img`).

+
+# :material-frequently-asked-questions: F.A.Q.
+
+## **Frequently-Asked-Questions**
+
+Here are a few common installation problems and their solutions. Often these are caused by
+incomplete installations or crashes during the install process.
+
+---
+
+### **QUESTION**
+
+During `conda env create`, conda hangs indefinitely.
+
+If it is because of the last PIP step (usually stuck in the Git Clone step, you can check the detailed log by this method):
+```bash
+export PIP_LOG="/tmp/pip_log.txt"
+touch ${PIP_LOG}
+tail -f ${PIP_LOG} & 
+conda env create -f environment-mac.yaml --debug --verbose
+killall tail
+rm ${PIP_LOG}
+```
+
+**SOLUTION**
+
+Conda sometimes gets stuck  at the last PIP step, in which several git repositories are
+cloned and built.
+
+Enter the stable-diffusion directory and completely remove the `src`
+directory and all its contents.  The safest way to do this is to enter
+the stable-diffusion directory and give the command `git clean -f`. If
+this still doesn't fix the problem, try "conda clean -all" and then
+restart at the `conda env create` step.
+
+To further understand the problem to checking the install lot using this method:
+
+```bash
+export PIP_LOG="/tmp/pip_log.txt"
+touch ${PIP_LOG}
+tail -f ${PIP_LOG} & 
+conda env create -f environment-mac.yaml --debug --verbose
+killall tail
+rm ${PIP_LOG}
+```
+
+---
+
+### **QUESTION**
+
+`dream.py` crashes with the complaint that it can't find `ldm.simplet2i.py`. Or it complains that
+function is being passed incorrect parameters.
+
+### **SOLUTION**
+
+Reinstall the stable diffusion modules. Enter the `stable-diffusion` directory and give the command
+`pip install -e .`
+
+---
+
+### **QUESTION**
+
+`dream.py` dies, complaining of various missing modules, none of which starts with `ldm``.
+
+### **SOLUTION**
+
+From within the `InvokeAI` directory, run `conda env update` This is also frequently the solution to
+complaints about an unknown function in a module.
+
+---
+
+### **QUESTION**
+
+There's a feature or bugfix in the Stable Diffusion GitHub that you want to try out.
+
+### **SOLUTION**
+
+#### **Main Branch**
+
+If the fix/feature is on the `main` branch, enter the stable-diffusion directory and do a
+`git pull`.
+
+Usually this will be sufficient, but if you start to see errors about
+missing or incorrect modules, use the command `pip install -e .`
+and/or `conda env update` (These commands won't break anything.)
+
+`pip install -e .` and/or
+
+`conda env update -f environment.yaml`
+
+(These commands won't break anything.)
+
+#### **Sub Branch**
+
+If the feature/fix is on a branch (e.g. "_foo-bugfix_"), the recipe is similar, but do a
+`git pull <name of branch>`.
+
+#### **Not Committed**
+
+If the feature/fix is in a pull request that has not yet been made part of the main branch or a
+feature/bugfix branch, then from the page for the desired pull request, look for the line at the top
+that reads "_xxxx wants to merge xx commits into lstein:main from YYYYYY_". Copy the URL in YYYY. It
+should have the format
+
+`https://github.com/<name of contributor>/stable-diffusion/tree/<name of branch>`
+
+Then **go to the directory above stable-diffusion** and rename the directory to
+"_stable-diffusion.lstein_", "_stable-diffusion.old_", or anything else. You can then git clone the
+branch that contains the pull request:
+
+`git clone https://github.com/<name of contributor>/stable-diffusion/tree/<name of branch>`
+
+You will need to go through the install procedure again, but it should be fast because all the
+dependencies are already loaded.

+
+### **QUESTION**
+
+Image generation crashed with CUDA out of memory error after successful sampling. 
+
+### **SOLUTION**
+
+Try to run script with option `--free_gpu_mem` This will free memory before image decoding step.

+# Before you begin
+
+- For end users: Install Stable Diffusion locally using the instructions for
+  your OS.
+- For developers: For container-related development tasks or for enabling easy
+  deployment to other environments (on-premises or cloud), follow these
+  instructions. For general use, install locally to leverage your machine's GPU.
+
+# Why containers?
+
+They provide a flexible, reliable way to build and deploy Stable Diffusion.
+You'll also use a Docker volume to store the largest model files and image
+outputs as a first step in decoupling storage and compute. Future enhancements
+can do this for other assets. See [Processes](https://12factor.net/processes)
+under the Twelve-Factor App methodology for details on why running applications
+in such a stateless fashion is important.
+
+You can specify the target platform when building the image and running the
+container. You'll also need to specify the Stable Diffusion requirements file
+that matches the container's OS and the architecture it will run on.
+
+Developers on Apple silicon (M1/M2): You
+[can't access your GPU cores from Docker containers](https://github.com/pytorch/pytorch/issues/81224)
+and performance is reduced compared with running it directly on macOS but for
+development purposes it's fine. Once you're done with development tasks on your
+laptop you can build for the target platform and architecture and deploy to
+another environment with NVIDIA GPUs on-premises or in the cloud.
+
+# Installation on a Linux container
+
+## Prerequisites
+
+### Get the data files
+
+Go to
+[Hugging Face](https://huggingface.co/CompVis/stable-diffusion-v-1-4-original),
+and click "Access repository" to Download the model file `sd-v1-4.ckpt` (~4 GB)
+to `~/Downloads`. You'll need to create an account but it's quick and free.
+
+Also download the face restoration model.
+
+```Shell
+cd ~/Downloads
+wget https://github.com/TencentARC/GFPGAN/releases/download/v1.3.0/GFPGANv1.4.pth
+```
+
+### Install [Docker](https://github.com/santisbon/guides#docker)
+
+On the Docker Desktop app, go to Preferences, Resources, Advanced. Increase the
+CPUs and Memory to avoid this
+[Issue](https://github.com/invoke-ai/InvokeAI/issues/342). You may need to
+increase Swap and Disk image size too.
+
+## Setup
+
+Set the fork you want to use and other variables.
+
+```Shell
+TAG_STABLE_DIFFUSION="santisbon/stable-diffusion"
+PLATFORM="linux/arm64"
+GITHUB_STABLE_DIFFUSION="-b orig-gfpgan https://github.com/santisbon/stable-diffusion.git"
+REQS_STABLE_DIFFUSION="requirements-linux-arm64.txt"
+CONDA_SUBDIR="osx-arm64"
+
+echo $TAG_STABLE_DIFFUSION
+echo $PLATFORM
+echo $GITHUB_STABLE_DIFFUSION
+echo $REQS_STABLE_DIFFUSION
+echo $CONDA_SUBDIR
+```
+
+Create a Docker volume for the downloaded model files.
+
+```Shell
+docker volume create my-vol
+```
+
+Copy the data files to the Docker volume using a lightweight Linux container.
+We'll need the models at run time. You just need to create the container with
+the mountpoint; no need to run this dummy container.
+
+```Shell
+cd ~/Downloads # or wherever you saved the files
+
+docker create --platform $PLATFORM --name dummy --mount source=my-vol,target=/data alpine
+
+docker cp sd-v1-4.ckpt dummy:/data
+docker cp GFPGANv1.4.pth dummy:/data
+```
+
+Get the repo and download the Miniconda installer (we'll need it at build time).
+Replace the URL with the version matching your container OS and the architecture
+it will run on.
+
+```Shell
+cd ~
+git clone $GITHUB_STABLE_DIFFUSION
+
+cd stable-diffusion/docker-build
+chmod +x entrypoint.sh
+wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-aarch64.sh -O anaconda.sh && chmod +x anaconda.sh
+```
+
+Build the Docker image. Give it any tag `-t` that you want.  
+Choose the Linux container's host platform: x86-64/Intel is `amd64`. Apple
+silicon is `arm64`. If deploying the container to the cloud to leverage powerful
+GPU instances you'll be on amd64 hardware but if you're just trying this out
+locally on Apple silicon choose arm64.  
+The application uses libraries that need to match the host environment so use
+the appropriate requirements file.  
+Tip: Check that your shell session has the env variables set above.
+
+```Shell
+docker build -t $TAG_STABLE_DIFFUSION \
+--platform $PLATFORM \
+--build-arg gsd=$GITHUB_STABLE_DIFFUSION \
+--build-arg rsd=$REQS_STABLE_DIFFUSION \
+--build-arg cs=$CONDA_SUBDIR \
+.
+```
+
+Run a container using your built image.  
+Tip: Make sure you've created and populated the Docker volume (above).
+
+```Shell
+docker run -it \
+--rm \
+--platform $PLATFORM \
+--name stable-diffusion \
+--hostname stable-diffusion \
+--mount source=my-vol,target=/data \
+$TAG_STABLE_DIFFUSION
+```
+
+# Usage (time to have fun)
+
+## Startup
+
+If you're on a **Linux container** the `dream` script is **automatically
+started** and the output dir set to the Docker volume you created earlier.
+
+If you're **directly on macOS follow these startup instructions**.  
+With the Conda environment activated (`conda activate ldm`), run the interactive
+interface that combines the functionality of the original scripts `txt2img` and
+`img2img`:  
+Use the more accurate but VRAM-intensive full precision math because
+half-precision requires autocast and won't work.  
+By default the images are saved in `outputs/img-samples/`.
+
+```Shell
+python3 scripts/dream.py --full_precision
+```
+
+You'll get the script's prompt. You can see available options or quit.
+
+```Shell
+dream> -h
+dream> q
+```
+
+## Text to Image
+
+For quick (but bad) image results test with 5 steps (default 50) and 1 sample
+image. This will let you know that everything is set up correctly.  
+Then increase steps to 100 or more for good (but slower) results.  
+The prompt can be in quotes or not.
+
+```Shell
+dream> The hulk fighting with sheldon cooper -s5 -n1
+dream> "woman closeup highly detailed"  -s 150
+# Reuse previous seed and apply face restoration
+dream> "woman closeup highly detailed"  --steps 150 --seed -1 -G 0.75
+```
+
+You'll need to experiment to see if face restoration is making it better or
+worse for your specific prompt.
+
+If you're on a container the output is set to the Docker volume. You can copy it
+wherever you want.  
+You can download it from the Docker Desktop app, Volumes, my-vol, data.  
+Or you can copy it from your Mac terminal. Keep in mind `docker cp` can't expand
+`*.png` so you'll need to specify the image file name.
+
+On your host Mac (you can use the name of any container that mounted the
+volume):
+
+```Shell
+docker cp dummy:/data/000001.928403745.png /Users/<your-user>/Pictures
+```
+
+## Image to Image
+
+You can also do text-guided image-to-image translation. For example, turning a
+sketch into a detailed drawing.
+
+`strength` is a value between 0.0 and 1.0 that controls the amount of noise that
+is added to the input image. Values that approach 1.0 allow for lots of
+variations but will also produce images that are not semantically consistent
+with the input. 0.0 preserves image exactly, 1.0 replaces it completely.
+
+Make sure your input image size dimensions are multiples of 64 e.g. 512x512.
+Otherwise you'll get `Error: product of dimension sizes > 2**31'`. If you still
+get the error
+[try a different size](https://support.apple.com/guide/preview/resize-rotate-or-flip-an-image-prvw2015/mac#:~:text=image's%20file%20size-,In%20the%20Preview%20app%20on%20your%20Mac%2C%20open%20the%20file,is%20shown%20at%20the%20bottom.)
+like 512x256.
+
+If you're on a Docker container, copy your input image into the Docker volume
+
+```Shell
+docker cp /Users/<your-user>/Pictures/sketch-mountains-input.jpg dummy:/data/
+```
+
+Try it out generating an image (or more). The `dream` script needs absolute
+paths to find the image so don't use `~`.
+
+If you're on your Mac
+
+```Shell
+dream> "A fantasy landscape, trending on artstation" -I /Users/<your-user>/Pictures/sketch-mountains-input.jpg --strength 0.75  --steps 100 -n4
+```
+
+If you're on a Linux container on your Mac
+
+```Shell
+dream> "A fantasy landscape, trending on artstation" -I /data/sketch-mountains-input.jpg --strength 0.75  --steps 50 -n1
+```
+
+## Web Interface
+
+You can use the `dream` script with a graphical web interface. Start the web
+server with:
+
+```Shell
+python3 scripts/dream.py --full_precision --web
+```
+
+If it's running on your Mac point your Mac web browser to http://127.0.0.1:9090
+
+Press Control-C at the command line to stop the web server.
+
+## Notes
+
+Some text you can add at the end of the prompt to make it very pretty:
+
+```Shell
+cinematic photo, highly detailed, cinematic lighting, ultra-detailed, ultrarealistic, photorealism, Octane Rendering, cyberpunk lights, Hyper Detail, 8K, HD, Unreal Engine, V-Ray, full hd, cyberpunk, abstract, 3d octane render + 4k UHD + immense detail + dramatic lighting + well lit + black, purple, blue, pink, cerulean, teal, metallic colours, + fine details, ultra photoreal, photographic, concept art, cinematic composition, rule of thirds, mysterious, eerie, photorealism, breathtaking detailed, painting art deco pattern, by hsiao, ron cheng, john james audubon, bizarre compositions, exquisite detail, extremely moody lighting, painted by greg rutkowski makoto shinkai takashi takeuchi studio ghibli, akihiko yoshida
+```
+
+The original scripts should work as well.
+
+```Shell
+python3 scripts/orig_scripts/txt2img.py --help
+python3 scripts/orig_scripts/txt2img.py --ddim_steps 100 --n_iter 1 --n_samples 1  --plms --prompt "new born baby kitten. Hyper Detail, Octane Rendering, Unreal Engine, V-Ray"
+python3 scripts/orig_scripts/txt2img.py --ddim_steps 5   --n_iter 1 --n_samples 1  --plms --prompt "ocean" # or --klms

+
+# :fontawesome-brands-linux: Linux
+
+## Installation
+
+1. You will need to install the following prerequisites if they are not already
+   available. Use your operating system's preferred installer.
+
+    - Python (version 3.8.5 recommended; higher may work)
+    - git
+
+2. Install the Python Anaconda environment manager.
+
+    ```bash
+    ~$  wget https://repo.anaconda.com/archive/Anaconda3-2022.05-Linux-x86_64.sh
+    ~$  chmod +x Anaconda3-2022.05-Linux-x86_64.sh
+    ~$  ./Anaconda3-2022.05-Linux-x86_64.sh
+    ```
+
+    After installing anaconda, you should log out of your system and log back in. If
+    the installation worked, your command prompt will be prefixed by the name of the
+    current anaconda environment - `(base)`.
+
+3. Copy the InvokeAI source code from GitHub:
+
+```
+(base) ~$ git clone https://github.com/invoke-ai/InvokeAI.git
+```
+
+This will create InvokeAI folder where you will follow the rest of the steps.
+
+4. Enter the newly-created InvokeAI folder. From this step forward make sure that you are working in the InvokeAI directory!
+
+```
+(base) ~$ cd InvokeAI
+(base) ~/InvokeAI$
+```
+
+5. Use anaconda to copy necessary python packages, create a new python
+   environment named `ldm` and activate the environment.
+
+
+```
+(base) ~/InvokeAI$ conda env create
+(base) ~/InvokeAI$ conda activate ldm
+(ldm) ~/InvokeAI$
+```
+
+    After these steps, your command prompt will be prefixed by `(ldm)` as shown
+    above.
+
+6. Load a couple of small machine-learning models required by stable diffusion:
+
+
+```
+(ldm) ~/InvokeAI$ python3 scripts/preload_models.py
+```
+
+    !!! note
+
+        This step is necessary because I modified the original just-in-time
+        model loading scheme to allow the script to work on GPU machines that are not
+        internet connected. See [Preload Models](../features/OTHER.md#preload-models)
+
+7. Now you need to install the weights for the stable diffusion model.
+
+      - For running with the released weights, you will first need to set up an acount
+        with [Hugging Face](https://huggingface.co).
+      - Use your credentials to log in, and then point your browser [here](https://huggingface.co/CompVis/stable-diffusion-v-1-4-original.)
+      - You may be asked to sign a license agreement at this point.
+      - Click on "Files and versions" near the top of the page, and then click on the
+        file named "sd-v1-4.ckpt". You'll be taken to a page that prompts you to click
+        the "download" link. Save the file somewhere safe on your local machine.
+
+      Now run the following commands from within the stable-diffusion directory.
+      This will create a symbolic link from the stable-diffusion model.ckpt file, to
+      the true location of the `sd-v1-4.ckpt` file.
+
+
+```
+(ldm) ~/InvokeAI$ mkdir -p models/ldm/stable-diffusion-v1
+(ldm) ~/InvokeAI$ ln -sf /path/to/sd-v1-4.ckpt models/ldm/stable-diffusion-v1/model.ckpt
+```
+
+8. Start generating images!
+
+```
+# for the pre-release weights use the -l or --liaon400m switch
+(ldm) ~/InvokeAI$ python3 scripts/dream.py -l
+
+# for the post-release weights do not use the switch
+(ldm) ~/InvokeAI$ python3 scripts/dream.py
+
+# for additional configuration switches and arguments, use -h or --help
+(ldm) ~/InvokeAI$ python3 scripts/dream.py -h
+```
+
+9. Subsequently, to relaunch the script, be sure to run "conda activate ldm" (step 5, second command), enter the `InvokeAI` directory, and then launch the dream script (step 8). If you forget to activate the ldm environment, the script will fail with multiple `ModuleNotFound` errors.
+
+## Updating to newer versions of the script
+
+
+This distribution is changing rapidly. If you used the `git clone` method (step 5) to download the InvokeAI directory, then to update to the latest and greatest version, launch the Anaconda window, enter `InvokeAI` and type:
+
+```
+(ldm) ~/InvokeAI$ git pull
+```
+
+This will bring your local copy into sync with the remote one.

+First get the weights checkpoint download started since it's big and will take
+some time:
+
+1. Sign up at [huggingface.co](https://huggingface.co)
+2. Go to the
+   [Stable diffusion diffusion model page](https://huggingface.co/CompVis/stable-diffusion-v-1-4-original)
+3. Accept the terms and click Access Repository:
+4. Download
+   [sd-v1-4.ckpt (4.27 GB)](https://huggingface.co/CompVis/stable-diffusion-v-1-4-original/blob/main/sd-v1-4.ckpt)
+   and note where you have saved it (probably the Downloads folder)
+
+While that is downloading, open a Terminal and run the following commands:
+
+!!! todo "Homebrew"
+
+    === "no brew installation yet"
+
+        ```bash title="install brew (and Xcode command line tools)"
+        /bin/bash -c \

+
+!!! todo "Conda Installation"
+
+    Now there are two different ways to set up the Python (miniconda) environment:
+    1. Standalone
+    2. with pyenv
+    If you don't know what we are talking about, choose Standalone
+
+    === "Standalone"
+
+        ```bash

+
+Note, `export PIP_EXISTS_ACTION=w` is a precaution to fix `conda env
+create -f environment-mac.yml` never finishing in some situations. So
+it isn't required but wont hurt.
+---
+
+## Common problems
+
+After you followed all the instructions and try to run dream.py, you might
+get several errors. Here's the errors I've seen and found solutions for.
+
+### Is it slow?
+
+```bash title="Be sure to specify 1 sample and 1 iteration."
+python ./scripts/orig_scripts/txt2img.py \
+  --prompt "ocean" \
+  --ddim_steps 5 \
+  --n_samples 1 \
+  --n_iter 1
+```
+
+---
+
+### Doesn't work anymore?
+
+PyTorch nightly includes support for MPS. Because of this, this setup is
+inherently unstable. One morning I woke up and it no longer worked no matter
+what I did until I switched to miniforge. However, I have another Mac that works
+just fine with Anaconda. If you can't get it to work, please search a little
+first because many of the errors will get posted and solved. If you can't find a
+solution please
+[create an issue](https://github.com/invoke-ai/InvokeAI/issues).
+
+One debugging step is to update to the latest version of PyTorch nightly.
+
+```bash
+conda install \
+  pytorch \
+  torchvision \
+  -c pytorch-nightly \
+  -n ldm
+```
+
+
+If it takes forever to run `conda env create -f environment-mac.yml`, try this:
+
+```bash
+git clean -f
+conda clean \
+  --yes \
+  --all
+```
+
+Or you could try to completley reset Anaconda:
+
+    ```bash
+    conda update \
+      --force-reinstall \
+      -y \
+      -n base \
+     -c defaults conda
+```
+
+---
+
+### "No module named cv2", torch, 'ldm', 'transformers', 'taming', etc
+
+There are several causes of these errors:
+
+1. Did you remember to `conda activate ldm`? If your terminal prompt begins with
+   "(ldm)" then you activated it. If it begins with "(base)" or something else
+   you haven't.
+
+2. You might've run `./scripts/preload_models.py` or `./scripts/dream.py`
+   instead of `python ./scripts/preload_models.py` or
+   `python ./scripts/dream.py`. The cause of this error is long so it's below.
+
+    <!-- I could not find out where the error is, otherwise would have marked it as a footnote -->
+
+3. if it says you're missing taming you need to rebuild your virtual
+   environment.
+
+    ```bash
+    conda deactivate
+    conda env remove -n ldm
+    conda env create -f environment-mac.yml
+    ```
+    
+4. If you have activated the ldm virtual environment and tried rebuilding it,
+   maybe the problem could be that I have something installed that you don't and
+   you'll just need to manually install it. Make sure you activate the virtual
+   environment so it installs there instead of globally.
+
+    ```bash
+    conda activate ldm
+    pip install <package name>
+    ```
+
+You might also need to install Rust (I mention this again below).
+
+---
+
+### How many snakes are living in your computer?
+
+You might have multiple Python installations on your system, in which case it's
+important to be explicit and consistent about which one to use for a given
+project. This is because virtual environments are coupled to the Python that
+created it (and all the associated 'system-level' modules).
+
+When you run `python` or `python3`, your shell searches the colon-delimited
+locations in the `PATH` environment variable (`echo $PATH` to see that list) in
+that order - first match wins. You can ask for the location of the first
+`python3` found in your `PATH` with the `which` command like this:
+
+```bash
+% which python3
+/usr/bin/python3
+```
+
+Anything in `/usr/bin` is
+[part of the OS](https://developer.apple.com/library/archive/documentation/FileManagement/Conceptual/FileSystemProgrammingGuide/FileSystemOverview/FileSystemOverview.html#//apple_ref/doc/uid/TP40010672-CH2-SW6).
+However, `/usr/bin/python3` is not actually python3, but rather a stub that
+offers to install Xcode (which includes python 3). If you have Xcode installed
+already, `/usr/bin/python3` will execute
+`/Library/Developer/CommandLineTools/usr/bin/python3` or
+`/Applications/Xcode.app/Contents/Developer/usr/bin/python3` (depending on which
+Xcode you've selected with `xcode-select`).
+
+Note that `/usr/bin/python` is an entirely different python - specifically,
+python 2. Note: starting in macOS 12.3, `/usr/bin/python` no longer exists.
+
+```bash
+% which python3
+/opt/homebrew/bin/python3
+```
+
+If you installed python3 with Homebrew and you've modified your path to search
+for Homebrew binaries before system ones, you'll see the above path.
+
+```bash
+% which python
+/opt/anaconda3/bin/python
+```
+
+If you have Anaconda installed, you will see the above path. There is a
+`/opt/anaconda3/bin/python3` also.
+
+We expect that `/opt/anaconda3/bin/python` and `/opt/anaconda3/bin/python3`
+should actually be the _same python_, which you can verify by comparing the
+output of `python3 -V` and `python -V`.
+
+```bash
+(ldm) % which python
+/Users/name/miniforge3/envs/ldm/bin/python
+```
+
+The above is what you'll see if you have miniforge and correctly activated the
+ldm environment, while usingd the standalone setup instructions above.
+
+If you otherwise installed via pyenv, you will get this result:
+
+```bash
+(anaconda3-2022.05) % which python
+/Users/name/.pyenv/shims/python
+```
+
+It's all a mess and you should know
+[how to modify the path environment variable](https://support.apple.com/guide/terminal/use-environment-variables-apd382cc5fa-4f58-4449-b20a-41c53c006f8f/mac)
+if you want to fix it. Here's a brief hint of the most common ways you can
+modify it (don't really have the time to explain it all here).
+
+- ~/.zshrc
+- ~/.bash_profile
+- ~/.bashrc
+- /etc/paths.d
+- /etc/path
+
+Which one you use will depend on what you have installed, except putting a file
+in /etc/paths.d - which also is the way I prefer to do.
+
+Finally, to answer the question posed by this section's title, it may help to
+list all of the `python` / `python3` things found in `$PATH` instead of just the
+first hit. To do so, add the `-a` switch to `which`:
+
+```bash
+% which -a python3
+...
+```
+
+This will show a list of all binaries which are actually available in your PATH.
+

+
+### Debugging?
+
+Tired of waiting for your renders to finish before you can see if it works?
+Reduce the steps! The image quality will be horrible but at least you'll get
+quick feedback.
+
+```bash
+python ./scripts/txt2img.py \
+  --prompt "ocean" \
+  --ddim_steps 5 \
+  --n_samples 1 \
+  --n_iter 1
+```
+
+---
+
+### OSError: Can't load tokenizer for 'openai/clip-vit-large-patch14'
+
+```bash
+python scripts/preload_models.py
+```
+
+---
+
+### "The operator [name] is not current implemented for the MPS device." (sic)
+
+!!! example "example error"
+
+    ```bash
+    ... NotImplementedError: The operator 'aten::_index_put_impl_' is not current
+    implemented for the MPS device. If you want this op to be added in priority
+    during the prototype phase of this feature, please comment on
+    https://github.com/pytorch/pytorch/issues/77764.
+    As a temporary fix, you can set the environment variable
+    `PYTORCH_ENABLE_MPS_FALLBACK=1` to use the CPU as a fallback for this op.
+    WARNING: this will be slower than running natively on MPS.
+    ```
+
+This fork already includes a fix for this in
+[environment-mac.yml](https://github.com/invoke-ai/InvokeAI/blob/main/environment-mac.yml).
+
+### "Could not build wheels for tokenizers"
+
+I have not seen this error because I had Rust installed on my computer before I
+started playing with Stable Diffusion. The fix is to install Rust.
+
+```bash
+curl \
+  --proto '=https' \
+  --tlsv1.2 \
+  -sSf https://sh.rustup.rs | sh
+```
+
+---
+
+### How come `--seed` doesn't work?
+
+First this:
+
+> Completely reproducible results are not guaranteed across PyTorch releases,
+> individual commits, or different platforms. Furthermore, results may not be
+> reproducible between CPU and GPU executions, even when using identical seeds.
+
+[PyTorch docs](https://pytorch.org/docs/stable/notes/randomness.html)
+
+Second, we might have a fix that at least gets a consistent seed sort of. We're
+still working on it.
+
+### libiomp5.dylib error?
+
+```bash
+OMP: Error #15: Initializing libiomp5.dylib, but found libomp.dylib already initialized.
+```
+
+You are likely using an Intel package by mistake. Be sure to run conda with the
+environment variable `CONDA_SUBDIR=osx-arm64`, like so:
+
+`CONDA_SUBDIR=osx-arm64 conda install ...`
+
+This error happens with Anaconda on Macs when the Intel-only `mkl` is pulled in
+by a dependency.
+[nomkl](https://stackoverflow.com/questions/66224879/what-is-the-nomkl-python-package-used-for)
+is a metapackage designed to prevent this, by making it impossible to install
+`mkl`, but if your environment is already broken it may not work.
+
+Do _not_ use `os.environ['KMP_DUPLICATE_LIB_OK']='True'` or equivalents as this
+masks the underlying issue of using Intel packages.
+
+---
+
+### Not enough memory
+
+This seems to be a common problem and is probably the underlying problem for a
+lot of symptoms (listed below). The fix is to lower your image size or to add
+`model.half()` right after the model is loaded. I should probably test it out.
+I've read that the reason this fixes problems is because it converts the model
+from 32-bit to 16-bit and that leaves more RAM for other things. I have no idea
+how that would affect the quality of the images though.
+
+See [this issue](https://github.com/CompVis/stable-diffusion/issues/71).
+
+---
+
+### "Error: product of dimension sizes > 2\*\*31'"
+
+This error happens with img2img, which I haven't played with too much yet. But I
+know it's because your image is too big or the resolution isn't a multiple of
+32x32. Because the stable-diffusion model was trained on images that were 512 x
+512, it's always best to use that output size (which is the default). However,
+if you're using that size and you get the above error, try 256 x 256 or 512 x
+256 or something as the source image.
+
+BTW, 2\*\*31-1 =
+[2,147,483,647](https://en.wikipedia.org/wiki/2,147,483,647#In_computing), which
+is also 32-bit signed [LONG_MAX](https://en.wikipedia.org/wiki/C_data_types) in
+C.
+
+---
+
+### I just got Rickrolled! Do I have a virus?
+
+You don't have a virus. It's part of the project. Here's
+[Rick](https://github.com/invoke-ai/InvokeAI/blob/main/assets/rick.jpeg)
+and here's
+[the code](https://github.com/invoke-ai/InvokeAI/blob/69ae4b35e0a0f6ee1af8bb9a5d0016ccb27e36dc/scripts/txt2img.py#L79)
+that swaps him in. It's a NSFW filter, which IMO, doesn't work very good (and we
+call this "computer vision", sheesh).
+
+Actually, this could be happening because there's not enough RAM. You could try
+the `model.half()` suggestion or specify smaller output images.
+
+---
+
+### My images come out black
+
+We might have this fixed, we are still testing.
+
+There's a [similar issue](https://github.com/CompVis/stable-diffusion/issues/69)
+on CUDA GPU's where the images come out green. Maybe it's the same issue?
+Someone in that issue says to use "--precision full", but this fork actually
+disables that flag. I don't know why, someone else provided that code and I
+don't know what it does. Maybe the `model.half()` suggestion above would fix
+this issue too. I should probably test it.
+
+### "view size is not compatible with input tensor's size and stride"
+
+```bash
+File "/opt/anaconda3/envs/ldm/lib/python3.10/site-packages/torch/nn/functional.py", line 2511, in layer_norm
+return torch.layer_norm(input, normalized_shape, weight, bias, eps, torch.backends.cudnn.enabled)
+RuntimeError: view size is not compatible with input tensor's size and stride (at least one dimension spans across two contiguous subspaces). Use .reshape(...) instead.
+```
+
+Update to the latest version of invoke-ai/InvokeAI. We were patching
+pytorch but we found a file in stable-diffusion that we could change instead.
+This is a 32-bit vs 16-bit problem.
+
+---
+
+### The processor must support the Intel bla bla bla
+
+What? Intel? On an Apple Silicon?
+
+```bash
+Intel MKL FATAL ERROR: This system does not meet the minimum requirements for use of the Intel(R) Math Kernel Library. The processor must support the Intel(R) Supplemental Streaming SIMD Extensions 3 (Intel(R) SSSE3) instructions. The processor must support the Intel(R) Streaming SIMD Extensions 4.2 (Intel(R) SSE4.2) instructions. The processor must support the Intel(R) Advanced Vector Extensions (Intel(R) AVX) instructions.
+```
+
+This is due to the Intel `mkl` package getting picked up when you try to install
+something that depends on it-- Rosetta can translate some Intel instructions but
+not the specialized ones here. To avoid this, make sure to use the environment
+variable `CONDA_SUBDIR=osx-arm64`, which restricts the Conda environment to only
+use ARM packages, and use `nomkl` as described above.

+## **Notebook install (semi-automated)**
+
+We have a
+[Jupyter notebook](https://github.com/invoke-ai/InvokeAI/blob/main/notebooks/Stable-Diffusion-local-Windows.ipynb)
+with cell-by-cell installation steps. It will download the code in this repo as
+one of the steps, so instead of cloning this repo, simply download the notebook
+from the link above and load it up in VSCode (with the appropriate extensions
+installed)/Jupyter/JupyterLab and start running the cells one-by-one.
+
+Note that you will need NVIDIA drivers, Python 3.10, and Git installed
+beforehand - simplified
+[step-by-step instructions](https://github.com/invoke-ai/InvokeAI/wiki/Easy-peasy-Windows-install)
+are available in the wiki (you'll only need steps 1, 2, & 3 ).
+
+## **Manual Install**
+
+### **pip**
+
+See
+[Easy-peasy Windows install](https://github.com/invoke-ai/InvokeAI/wiki/Easy-peasy-Windows-install)
+in the wiki
+
+---
+
+### **Conda**
+
+1. Install Anaconda3 (miniconda3 version) from [here](https://docs.anaconda.com/anaconda/install/windows/)
+
+2. Install Git from [here](https://git-scm.com/download/win)
+
+3. Launch Anaconda from the Windows Start menu. This will bring up a command
+   window. Type all the remaining commands in this window.
+
+4. Run the command:
+
+    ```bash
+    git clone https://github.com/invoke-ai/InvokeAI.git
+    ```
+
+    This will create stable-diffusion folder where you will follow the rest of
+    the steps.
+
+5. Enter the newly-created InvokeAI folder. From this step forward make sure that you are working in the InvokeAI directory!
+
+```
+cd InvokeAI
+```
+
+6. Run the following two commands:
+
+```
+conda env create       (step 6a)
+conda activate ldm     (step 6b)
+```
+    This will install all python requirements and activate the "ldm" environment
+    which sets PATH and other environment variables properly.
+
+    Note that the long form of the first command is `conda env create -f environment.yml`. If the
+    environment file isn't specified, conda will default to `environment.yml`. You will need
+    to provide the `-f` option if you wish to load a different environment file at any point.
+
+7. Run the command:
+
+    ```bash
+    python scripts\preload_models.py
+    ```
+
+    This installs several machine learning models that stable diffusion requires.
+
+    Note: This step is required. This was done because some users may might be
+    blocked by firewalls or have limited internet connectivity for the models to
+    be downloaded just-in-time.
+
+8. Now you need to install the weights for the big stable diffusion model.
+
+- For running with the released weights, you will first need to set up an acount with Hugging Face (https://huggingface.co).
+- Use your credentials to log in, and then point your browser at https://huggingface.co/CompVis/stable-diffusion-v-1-4-original.
+- You may be asked to sign a license agreement at this point.
+- Click on "Files and versions" near the top of the page, and then click on the file named `sd-v1-4.ckpt`. You'll be taken to a page that
+  prompts you to click the "download" link. Now save the file somewhere safe on your local machine.
+- The weight file is >4 GB in size, so
+  downloading may take a while.
+
+Now run the following commands from **within the InvokeAI directory** to copy the weights file to the right place:
+
+```
+mkdir -p models\ldm\stable-diffusion-v1
+copy C:\path\to\sd-v1-4.ckpt models\ldm\stable-diffusion-v1\model.ckpt
+```
+
+Please replace `C:\path\to\sd-v1.4.ckpt` with the correct path to wherever you stashed this file. If you prefer not to copy or move the .ckpt file,
+you may instead create a shortcut to it from within `models\ldm\stable-diffusion-v1\`.
+
+9. Start generating images!
+
+    ```bash

+
+![txt2img-stable2](../assets/stable-samples/txt2img/merged-0006.png)
+[Stable Diffusion](#stable-diffusion-v1) is a latent text-to-image diffusion
+model. Thanks to a generous compute donation from
+[Stability AI](https://stability.ai/) and support from
+[LAION](https://laion.ai/), we were able to train a Latent Diffusion Model on
+512x512 images from a subset of the [LAION-5B](https://laion.ai/blog/laion-5b/)
+database. Similar to Google's [Imagen](https://arxiv.org/abs/2205.11487), this
+model uses a frozen CLIP ViT-L/14 text encoder to condition the model on text
+prompts. With its 860M UNet and 123M text encoder, the model is relatively
+lightweight and runs on a GPU with at least 10GB VRAM. See
+[this section](#stable-diffusion-v1) below and the
+[model card](https://huggingface.co/CompVis/stable-diffusion).
+
+## Requirements
+
+A suitable [conda](https://conda.io/) environment named `ldm` can be created and
+activated with:
+
+```
+conda env create
+conda activate ldm
+```
+
+Note that the first line may be abbreviated `conda env create`, since conda will
+look for `environment.yml` by default.
+
+You can also update an existing
+[latent diffusion](https://github.com/CompVis/latent-diffusion) environment by
+running
+
+```bash
+conda install pytorch torchvision -c pytorch
+pip install transformers==4.19.2
+pip install -e .
+```
+
+## Stable Diffusion v1
+
+Stable Diffusion v1 refers to a specific configuration of the model architecture
+that uses a downsampling-factor 8 autoencoder with an 860M UNet and CLIP
+ViT-L/14 text encoder for the diffusion model. The model was pretrained on
+256x256 images and then finetuned on 512x512 images.
+
+\*Note: Stable Diffusion v1 is a general text-to-image diffusion model and
+therefore mirrors biases and (mis-)conceptions that are present in its training
+data. Details on the training procedure and data, as well as the intended use of
+the model can be found in the corresponding
+[model card](https://huggingface.co/CompVis/stable-diffusion). Research into the
+safe deployment of general text-to-image models is an ongoing effort. To prevent
+misuse and harm, we currently provide access to the checkpoints only for
+[academic research purposes upon request](https://stability.ai/academia-access-form).
+**This is an experiment in safe and community-driven publication of a capable
+and general text-to-image model. We are working on a public release with a more
+permissive license that also incorporates ethical considerations.\***
+
+[Request access to Stable Diffusion v1 checkpoints for academic research](https://stability.ai/academia-access-form)
+
+### Weights
+
+We currently provide three checkpoints, `sd-v1-1.ckpt`, `sd-v1-2.ckpt` and
+`sd-v1-3.ckpt`, which were trained as follows,
+
+- `sd-v1-1.ckpt`: 237k steps at resolution `256x256` on
+  [laion2B-en](https://huggingface.co/datasets/laion/laion2B-en). 194k steps at
+  resolution `512x512` on
+  [laion-high-resolution](https://huggingface.co/datasets/laion/laion-high-resolution)
+  (170M examples from LAION-5B with resolution `>= 1024x1024`).
+- `sd-v1-2.ckpt`: Resumed from `sd-v1-1.ckpt`. 515k steps at resolution
+  `512x512` on "laion-improved-aesthetics" (a subset of laion2B-en, filtered to
+  images with an original size `>= 512x512`, estimated aesthetics score `> 5.0`,
+  and an estimated watermark probability `< 0.5`. The watermark estimate is from
+  the LAION-5B metadata, the aesthetics score is estimated using an
+  [improved aesthetics estimator](https://github.com/christophschuhmann/improved-aesthetic-predictor)).
+- `sd-v1-3.ckpt`: Resumed from `sd-v1-2.ckpt`. 195k steps at resolution
+  `512x512` on "laion-improved-aesthetics" and 10\% dropping of the
+  text-conditioning to improve
+  [classifier-free guidance sampling](https://arxiv.org/abs/2207.12598).
+
+Evaluations with different classifier-free guidance scales (1.5, 2.0, 3.0, 4.0,
+5.0, 6.0, 7.0, 8.0) and 50 PLMS sampling steps show the relative improvements of
+the checkpoints: ![sd evaluation results](../assets/v1-variants-scores.jpg)
+
+### Text-to-Image with Stable Diffusion
+
+![txt2img-stable2](../assets/stable-samples/txt2img/merged-0005.png)
+![txt2img-stable2](../assets/stable-samples/txt2img/merged-0007.png)
+
+Stable Diffusion is a latent diffusion model conditioned on the (non-pooled)
+text embeddings of a CLIP ViT-L/14 text encoder.
+
+#### Sampling Script
+
+After [obtaining the weights](#weights), link them
+
+```
+mkdir -p models/ldm/stable-diffusion-v1/
+ln -s <path/to/model.ckpt> models/ldm/stable-diffusion-v1/model.ckpt
+```
+
+and sample with
+
+```
+python scripts/txt2img.py --prompt "a photograph of an astronaut riding a horse" --plms
+```
+
+By default, this uses a guidance scale of `--scale 7.5`,
+[Katherine Crowson's implementation](https://github.com/CompVis/latent-diffusion/pull/51)
+of the [PLMS](https://arxiv.org/abs/2202.09778) sampler, and renders images of
+size 512x512 (which it was trained on) in 50 steps. All supported arguments are
+listed below (type `python scripts/txt2img.py --help`).
+
+```commandline
+usage: txt2img.py [-h] [--prompt [PROMPT]] [--outdir [OUTDIR]] [--skip_grid] [--skip_save] [--ddim_steps DDIM_STEPS] [--plms] [--laion400m] [--fixed_code] [--ddim_eta DDIM_ETA] [--n_iter N_ITER] [--H H] [--W W] [--C C] [--f F] [--n_samples N_SAMPLES] [--n_rows N_ROWS]
+                  [--scale SCALE] [--from-file FROM_FILE] [--config CONFIG] [--ckpt CKPT] [--seed SEED] [--precision {full,autocast}]
+
+optional arguments:
+  -h, --help            show this help message and exit
+  --prompt [PROMPT]     the prompt to render
+  --outdir [OUTDIR]     dir to write results to
+  --skip_grid           do not save a grid, only individual samples. Helpful when evaluating lots of samples
+  --skip_save           do not save individual samples. For speed measurements.
+  --ddim_steps DDIM_STEPS
+                        number of ddim sampling steps
+  --plms                use plms sampling
+  --laion400m           uses the LAION400M model
+  --fixed_code          if enabled, uses the same starting code across samples
+  --ddim_eta DDIM_ETA   ddim eta (eta=0.0 corresponds to deterministic sampling
+  --n_iter N_ITER       sample this often
+  --H H                 image height, in pixel space
+  --W W                 image width, in pixel space
+  --C C                 latent channels
+  --f F                 downsampling factor
+  --n_samples N_SAMPLES
+                        how many samples to produce for each given prompt. A.k.a. batch size
+                        (note that the seeds for each image in the batch will be unavailable)
+  --n_rows N_ROWS       rows in the grid (default: n_samples)
+  --scale SCALE         unconditional guidance scale: eps = eps(x, empty) + scale * (eps(x, cond) - eps(x, empty))
+  --from-file FROM_FILE
+                        if specified, load prompts from this file
+  --config CONFIG       path to config which constructs model
+  --ckpt CKPT           path to checkpoint of model
+  --seed SEED           the seed (for reproducible sampling)
+  --precision {full,autocast}
+                        evaluate at this precision
+
+```
+
+Note: The inference config for all v1 versions is designed to be used with
+EMA-only checkpoints. For this reason `use_ema=False` is set in the
+configuration, otherwise the code will try to switch from non-EMA to EMA
+weights. If you want to examine the effect of EMA vs no EMA, we provide "full"
+checkpoints which contain both types of weights. For these, `use_ema=False` will
+load and use the non-EMA weights.
+
+#### Diffusers Integration
+
+Another way to download and sample Stable Diffusion is by using the
+[diffusers library](https://github.com/huggingface/diffusers/tree/main#new--stable-diffusion-is-now-fully-compatible-with-diffusers)
+
+```py
+# make sure you're logged in with `huggingface-cli login`
+from torch import autocast
+from diffusers import StableDiffusionPipeline, LMSDiscreteScheduler
+
+pipe = StableDiffusionPipeline.from_pretrained(
+	"CompVis/stable-diffusion-v1-3-diffusers",
+	use_auth_token=True
+)
+
+prompt = "a photo of an astronaut riding a horse on mars"
+with autocast("cuda"):
+    image = pipe(prompt)["sample"][0]
+
+image.save("astronaut_rides_horse.png")
+```
+
+### Image Modification with Stable Diffusion
+
+By using a diffusion-denoising mechanism as first proposed by
+[SDEdit](https://arxiv.org/abs/2108.01073), the model can be used for different
+tasks such as text-guided image-to-image translation and upscaling. Similar to
+the txt2img sampling script, we provide a script to perform image modification
+with Stable Diffusion.
+
+The following describes an example where a rough sketch made in
+[Pinta](https://www.pinta-project.com/) is converted into a detailed artwork.
+
+```
+python scripts/img2img.py --prompt "A fantasy landscape, trending on artstation" --init-img <path-to-img.jpg> --strength 0.8
+```
+
+Here, strength is a value between 0.0 and 1.0, that controls the amount of noise
+that is added to the input image. Values that approach 1.0 allow for lots of
+variations but will also produce images that are not semantically consistent
+with the input. See the following example.
+
+**Input**
+
+![sketch-in](../assets/stable-samples/img2img/sketch-mountains-input.jpg)
+
+**Outputs**
+
+![out3](../assets/stable-samples/img2img/mountains-3.png)
+![out2](../assets/stable-samples/img2img/mountains-2.png)
+
+This procedure can, for example, also be used to upscale samples from the base
+model.
+
+## Comments
+
+- Our codebase for the diffusion models builds heavily on
+  [OpenAI's ADM codebase](https://github.com/openai/guided-diffusion) and
+  [https://github.com/lucidrains/denoising-diffusion-pytorch](https://github.com/lucidrains/denoising-diffusion-pytorch).
+  Thanks for open-sourcing!
+
+- The implementation of the transformer encoder is from
+  [x-transformers](https://github.com/lucidrains/x-transformers) by
