xformers compiled for specific graphics cards.
These wheels were build on and for Paperspace Gradient machines for use with Engineer-of-Stuff/stable-diffusion-paperspace.
Xformers was compiled without a few features to make the binary smaller and compile time shorter:
XFORMERS_DISABLE_FLASH_ATTN=1 NVCC_FLAGS="--use_fast_math -DXFORMERS_MEM_EFF_ATTENTION_DISABLE_BACKWARD"
If you get error messages talking about missing xformers modules, use the full version of the wheel located in the card's folder.
