Sageattention for windows

Worked for me on python 3.13 and torch 2.8.0+cu129.

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

Give a try!

it is
sageattn3-1.0.0+cu128torch2.8.0-cp311-cp311-win_amd64.whl
it is usable？

I'm having issues as well, with both cuda 12.8 and 13.0 on python 3.12 (didn't bother with 3.13 as I thought it would be incompatible) but on kubuntu 25.04, so windows wheels won't do it

I had a similar if not identical problem, if my patch script works for you, do let us know: #228 (comment)

This was what helped me get sageattention2.2 installed on Linux, thanks!
