flash-attention pre-build wheels

This repository provides wheels for the pre-build flash-attention.

Since building flash-attention takes a very long time and is resource-intensive, I also build and provide combinations of CUDA and PyTorch that are not officially distributed.

The building Github Actions Workflow can be found here.

The built packages are available on the release page.
