The fixes in this module monkeypatched `torch` to resolve some issues with FP16 on macOS. These issues have long since been resolved.
Included in the now-removed fixes is `CustomSlicedAttentionProcessor`, which is intended to reduce memory requirements for MPS. This overrides `diffusers`' own `SlicedAttentionProcessor`.
Unfortunately, `attention_type: sliced` produces hot garbage with the fixes and black images without the fixes. So this class appears to now be a moot point.
Regardless, SDPA is supported on MPS and very efficient, so sliced attention is largely obsolete.
The top-level `invokeai` package may have an obscured origin due to the way editible installs work, but it's much more likely that this module is from a specific file.
