I went to the URL https://download.pytorch.org/whl/nightly/cu128 to see the last version for each package, and installed them:

pip install --pre torch==2.8.0.dev20250605+cu128 torchvision==0.23.0.dev20250605+cu128 torchaudio==2.8.0.dev20250605+cu128 --index-url https://download.pytorch.org/whl/nightly/cu128

Now ComfyUI works with my 5060.
