I had the same issue and find a way to make it work.
1)First, I did a clean installation of comfy ui by deleting the apps and all the folder (don’t know if it’s useful, but I find out the windows uninstaller don’t deleted everything)
-
C:\Users[windows_username]\AppData\Local\Programs → deleted @comfyorgcomfyui-electroncomfyorgcomfyui-electroncomfyorgcomfyui-electroncomfyorgcomfyui-electron
-
C:\Users[windows_username]\A@comfyor@comfyorgcomfyui-electron-updatercomfyui-electron-updaterpData\Local\ → deleted @comfyorgcomfyui-electron-updater
-
C:\Users[windows_username]\AppData\Local\uv → deleted this whole folder
-
C:\Users[windows_username]\AppData\Roaming → deleted ComfyUI folder
- reinstallation of ComfyUI
same step has usual chose the nvdia gpu and…at the mirror setting page
in the torch install mirror, the address written is https://download.pytorch.org/whl/cu129
cu129 is not compatible with the GTX. I change the cu129 for cu126 (https://download.pytorch.org/whl/cu126) and completed the installation normally.
Now I can use comfy with my gtx 1080 ti again. And the error is gone
hope it works for you!
