It seems the new graphic cards don't work on the current installed cuda version

Take a look here
lllyasviel/stable-diffusion-webui-forge#2601

I tried running the update command directly inside the container

pip install --pre torch torchvision torchaudio --index-url https://download.pytorch.org/whl/nightly/cu128

Now I get another error about xformers need to be updated or something
I think we need to set env variable for the xformers here
like mentioned here AUTOMATIC1111/stable-diffusion-webui#16818
but now sure how for your image.
