pre-built flash-attn can also be downloaded from here https://github.com/mjun0812/flash-attention-prebuild-wheels, which might be the better source because they have automated the build process, so more likely will keep it up to date. the (automated, I guess) versioning there is a bit strange though. It doesn't always update all platforms. This version seems to be the latest release for windows: @Calamdor FYI |

brings back attention selection, that was removed in 482333f when xformers wasn't used anymore
Can be used to select flash attention, which is faster on windows because torch SDP doesn't support flash internally on Windows
It can be selected, but it must be manually installed from here: https://github.com/zzlol63/flash-attention-prebuild-wheels/releases
thank you to @zzlol63 for the investigation: #1090
Uses huggingface/diffusers#12892 to raise an error if flash attention cannot be used because of attention masks.
