Fix for Blackwell GPU and ComfyUI (probably other things)

[EpicMulletGuy]

Found that my ComfyUI broke today after an update and the usual way to install the prerelease torch, torchvision and torchaudio failed. However, the following works as a workaround for anyone else who gets stuck.

If you are using Stability Matrix just click the 3 dots next to comfyui in the UI and head to "Python Packages". Hit the + icon and enter
--pre "torch==2.8.0.*" "torchvision==0.22.0.*" "torchaudio==2.6.0.*" --index-url https://download.pytorch.org/whl/nightly/cu128
Hit return, wait a bit and you should now be up and running again.

Hope this helps a few.
