Not sure if this is the right place to ask but I just started using ComfyUI for Wan2.1 and I keep getting this error repeatedly while trying to use SageAttention
"Error running sage attention: SM89 kernel is not available. Make sure you GPUs with compute capability 8.9., using pytorch attention instead."
I'm using a 5070TI
Driver: 572.60
I used the ComfyUI Easy Installer and also used the SageAttention bat file that said it installed that and Triton, I don't really know what to do, has anyone had this issue? I got the installer from here
