    Try going to ... symbol at the top right corner of your ComfyUI package that fails, then Python packages, then +, then add this:

    pip install torch torchvision torchaudio xformers --index-url https://download.pytorch.org/whl/cu129

    wait for download to finish and see if that helps.

    At the moment, I'm using it with pytorch 2.8+cuda12.8, I'll wait a while to update. Thanks!
