The full file name is: xformers-0.0.16+bc08bbc.d20230126-cp37-cp37m-linux_x86_64.whl
This was compiled on Kaggle (and works there!) with Python 3.7.12, with a Nvidia P100 GPU. Should you want to do use this with Automatic1111 Stable Diffusion web UI with this old Python 3.7 version, you require a modified requirements_versions.txt. I'm attaching it also below.
Used Pytorch was:
!pip install torch==1.13.1+cu116 torchvision==0.14.1+cu116 --extra-index-url https://download.pytorch.org/whl/cu116
To install xformers:
!pip install https://github.com/Testertime/xformers-wheels_Dec2022/releases/download/why_are_tags_needed/xformers-0.0.16+bc08bbc.d20230126-cp37-cp37m-linux_x86_64.whl
Edit: Added version for Python 3.8.13 and others, same Torch version and all. Hopefully it was worth the wait! Thanks, and have fun.
