Can't get Sageattention to work after 0.7.2 Update (Desktop)

Hi there.

After an whole odyssey trying to fix ConfyUI Desktop after 0.7.2 update (after 2 hours of troubleshooting and a couple reinstalls and fresh installs), I’m now at a somewhat stable point…

The problem is that now, the desktop app is running Pytorch Version 2.9.1+cu130 witch probably broke SageAttention functionality. I was previously running Pytorch 2.7.1+cu128 and Saeattention (sageattention-2.2.0+cu128torch2.7.1-cp312-cp312-win_amd64.whl) and it was working fine.

This is the error i get after installing new wheel for sageattention(sageattention-2.2.0+cu128torch2.8.0-cp312-cp312-win_amd64.whl) and Triton:

Do not know if the problem really is a conflict with Pytorch version or something else….
For what i understand, Sageattention should not work yet with Pytorch 2.9… right?

If so, any safe way to downgrade the Pytorch version to 2.7?
Everytime i tried to upgrade or downgrade Pytorch on ConfyUI Desktop, my installation always became a total mess!!!

Any help would be appreciated… Thanks!

Check this wheels for torch 2.9 (but in release, as I remember, torch 2.9.1 - may be a problem).

Thanks for the tip.
I tried all of them i could (for cp3.12) and it still gives the same error…

I think i’ll wait till a new proper sageattention wheel is provided.

You know of any safe way to downgrade Pytorch on ConfyUI Desktop without reverting to a previous version of the app? (0.6.x was working fine)
If that is even possible that is….
