LTX-2 MPS Patcher
patches diffusers to run ltx-2 on apple silicon (mps).
Patches the diffusers library to enable LTX-2 on Apple Silicon (MPS).
The issue is that LTX-2 uses float64 for RoPE calculations, but MPS doesn't support float64.
This script forces float32 which works fine for video generation.
ltx-2 uses float64 for rope, but mps doesn't support it.
this forces float32 instead - works fine.
Usage:
python patch_mps.py
Requirements:
- diffusers (dev version with LTX2Pipeline)
- pip install git+https://github.com/huggingface/diffusers.git
usage: python patch_mps.py
