- Introduced `--cpu_offload` argument in `generate.py` for enabling CPU offload. - Updated `WanI2V` class in `image2video.py` to handle CPU offload during model initialization and sharding. - Added new functions in `fsdp.py` for CPU initialization and sharding with CPU offload. - Expanded supported sizes in `configs/__init__.py` to include additional resolutions.
