This issue might be caused by missing dependencies. Please do a: pip install -r requirements.txt

But there is no req.txt to install for this directory.

They are built-in nodes. ComfyUI/requirements.txt

Found here through Google, I have solved the same error, which is caused by the lack of flash-attention. It is really not in the requirements.txt. You could to go to https://github.com/bdashore3/flash-attention/releases , install a wheel that matches your version of torch and Cuda

For example (Just an example, version may not match yours): pip install https://github.com/bdashore3/flash-attention/releases/download/v2.5.6/flash_attn-2.5.6+cu122torch2.2.2cxx11abiFALSE-cp311-cp311-win_amd64.whl

hope that useful to you

Also say hello to ltdrdata here in the post, thanks for your nodes and tutorials they are great!

Thanks for @Packsod's inspiration.

I am a Linux user, I used the installation method in https://github.com/Dao-AILab/flash-attention to install flash-attention manually, and finally my error was successfully solved!

Thanks again!
