Add support for WAN 2.2 model
This PR introduces support for the WAN 2.2 model and refactors the existing pipeline to dynamically handle multiple model versions.
New Model Support (WAN 2.2)
The core logic, configuration, and checkpointing for the WAN 2.2 model are added:
base_wan_27b.yml: New configuration file for the WAN 2.2 (27B) model.wan_pipeline2_2.py: The dedicated processing pipeline for WAN 2.2.wan_checkpointer2_2.py: Handles checkpoint loading/saving specific to the v2.2 architecture.wan_checkpointer2_2_test.py: Tests for wan_checkpointer2_2.pyRefactoring for Multi-Model Support
To allow the system to select between WAN 2.1 and 2.2, several core files were modified:
generate_wan.py: Adds a --model_name flag. This flag is now used to dynamically load the correct configuration file (e.g.,base_wan_14b.ymlorbase_wan_27b.yml).wan_utils.py: Updated all transformer loading functions to include a subfolder parameter.base_wan_14b.yml: Added the model_name parameter to conform to the new configuration standard.Note on Future Work
As a follow-up to this PR, the separate
wan_pipeline.py/wan_pipeline2_2.pyandwan_checkpointer.py/wan_checkpointer2_2.pyfiles will be merged. This current separation is a temporary step to land WAN 2.2 support.We tested the above pipeline for both WAN 2.1 and WAN 2.2 with exact same configurations, and the numbers for both the cases are similar.
