How to use Sage Attention 2++ ?

Thank you !

I think sageattn will load SageAttention2++ because it's the same package in Python ?

sageattn will use whichever sageattn you have installed, you can't have multiple different versions anyway between sage1 and sage2.

Sage3 is special case as it's only for blackwell GPUs.

Have you solved it? I get a black screen when I use sageattn2 (node selection sageattn).

After I switched the sageattn version to v1, this problem disappeared, but there was also no faster inference speed, compared to flash_attn (fp8scale model on A100).
