# Distinguish LoRA/LyCORIS files based on what version of SD they were
built on top of
- Attempting to run a prompt with a LoRA based on SD v1.X against a
model based on v2.X will now throw an `IncompatibleModelException`. To
import this exception:
`from ldm.modules.lora_manager import IncompatibleModelException` (maybe
this should be defined in ModelManager?)
- Enhance `LoraManager.list_loras()` to accept an optional integer
argument, `token_vector_length`. This will filter the returned LoRA
models to return only those that match the indicated length. Use:
```
768 => for models based on SD v1.X
1024 => for models based on SD v2.X
```
Note that this filtering requires each LoRA file to be opened by
`torch.safetensors`. It will take ~8s to scan a directory of 40 files.
- Added new static methods to `ldm.modules.kohya_lora_manager`:
- check_model_compatibility()
- vector_length_from_checkpoint()
- vector_length_from_checkpoint_file()
- You can now create subdirectories within the `loras` directory and
organize the model files.
- Moved all postinstallation config file and model munging code out of
the CLI and into a separate script named `invokeai-postinstall`
- Fixed two calls to `shutil.copytree()` so that they don't try to
preserve the file mode of the copied files. This is necessary to run
correctly in a Nix environment (see thread at
https://discord.com/channels/1020123559063990373/1091716696965918732/1095662756738371615)
- Update the installer so that an existing virtual environment will be
updated, not overwritten.
- Pin npyscreen version to see if this fixes issues people have had with
installing this module.
Load LoRAs during compel's text embedding encode pass in case there are
requested LoRAs which also want to patch the text encoder.
Also generally cleanup the attention processor patching stuff. It's
still a mess, but at least now it's a *stateless* mess.
Both @mauwii and @keturn have been offline for some time. I am
temporarily removing them from CODEOWNERS so that they will not be
responsible for code reviews until they wish to/are able to re-engage
fully.
Note that I have volunteered @GreggHelt2 to be a codeowner of the
generation backend code, replacing @keturn . Let me know if you're
uncomfortable with this.
- Pin diffusers to 0.14
- Small fix to LoRA loading routine that was preventing placement of
LoRA files in subdirectories.
- Bump version to 2.3.4.post1
