Step 8: Install Flash Attention (Optional)
This repository was created to address a common pain point for AI enthusiasts and developers on the Windows platform: building complex Python packages from source. Libraries like flash-attention, xformers are essential for high-performance AI tasks but often lack official pre-built wheels for Windows, forcing users into a complicated and error-prone compilation process.
The goal here is to provide a centralized, up-to-date collection of direct links to pre-compiled .whl files for these libraries, primarily for the ComfyUI community and other PyTorch users on Windows. This saves you time and lets you focus on what’s important: creating amazing things with AI.
Pick one that match your CUDA, Python, and Torch Version
For example:
Matches cu128 (CUDA 12.8), cp312 (Python 3.12), and base Torch 2.7.x.
Matches cu128 (CUDA 12.8), cp312 (Python 3.12), and base Torch 2.9.x.
python_embeded\python.exe -m pip install xxxxxxx.whl
Verify:
python_embeded\python.exe -c "import flash_attn; print('Ready:', flash_attn.__version__)"
