[Bug]: Torch is not able to use GPU

[b-fission]

You should update your nvidia graphics driver.
The log says your driver version is 511.69, which is too old for CUDA 12.1

Happened to me this morning on an install that has been running fine for months. Updated extensions, (I think adetailer and controlnet updated), and when I re-launched the webui, got the same error. (Edit: Rolling back the extensions and disabling the extensions did not help.)

Updated Nvidia driver and CUDA, still got the same error.

What worked for me was re-installing Torch, (added --reinstall-torch to COMMANDLINE_ARGS in webui-user.bat), and re-running it. (Downloaded the latest Torch (about 2.5GB).)

(Remember to remove that parameter before you run it again or it'll install every time.)

(It did throw an error about Xformers, but I'm using --opt-sdp-attention instead and it didn't seem to affect anything.)

Hope that helps (somebody). :D

No xformers fit for torch-2.1.2+cu121. When u pip install any version xformers , the torch-2.1.2+cu121 will be uninstall automatically and install torch-2.1 or 2.3 automatically.
