   same problem here, sageattention 1.0.6 seemed to "work" but i was not sure. i had troubles with qwen models when using it and i could never update it from stability matrix extension menu. always error message.

   when uninstalling it and trying to install, i get the same error, no "torch" installed, but also 2.8.0+cu129 and mostly working normally.
