This commit introduces a major architectural refactoring, laying the groundwork for DisTorch V2. The changes focus on improving modularity, memory management, and diagnostics.
Key changes include:
- Renaming `distorch_safetensor.py` to `distorch_2.py` to house the new core logic.
- Deleting the legacy `block_swap.py` module.
- Adding `device_memory_audit.py` for more sophisticated analysis of GPU memory usage.
- Implementing a centralized and configurable logging system in `__init__.py` to provide standardized and level-controlled (DEBUG/INFO) output for better debugging.
This commit refactors the codebase by extracting major components from the main `__init__.py` file into their own dedicated modules. This improves code organization, readability, and maintainability.
- **`distorch.py`**: New file containing the `DisTorch` class, which manages multi-GPU device patching and distribution logic.
- **`block_swap.py`**: New file containing the generic `BlockSwap` class for UNet block swapping to manage VRAM.
- **`wanvideo.py`**: New file containing the `WanVideoBlockSwap` class, a specialized implementation for WanVideo models.
- **`__init__.py`**: Simplified to handle node registration and imports from the new modules.
