This pull request adds a detailed troubleshooting guide to the README.md to resolve compatibility issues when running the Wan-Animate preprocessing script.
Problem:
Users on certain modern environments (e.g., Ubuntu 22.04, Python 3.12) encounter fatal errors during the preprocess_data.py step for Wan-Animate. These errors can manifest as:
ImportError: undefined symbol
KeyError: 'frames_tracked_per_obj'
These issues are caused by an ABI incompatibility between the pre-compiled sam-2 package and the user's PyTorch/CUDA environment.
Solution:
This PR adds a collapsible "details" section to the Run Wan-Animate documentation. This new section provides clear, step-by-step instructions for:
Setting up the correct build environment (GCC-12, etc.).
Configuring necessary environment variables (CC, CXX, CUDA_HOME).
Re-installing the sam-2 package from a specific Git commit to ensure it compiles against the local environment.
Manually building the C++ extension in-place to finalize the fix.
This documentation change will help users self-service these common build issues and improve the out-of-the-box experience for the Wan-Animate module.
Closes #157[https://github.com//issues/157]
