Is it possible to install it manually such as go to terminal, then go to Slicer-5.8.1./bin and run ./PythonSlicer -m pip install to install pytorch with cu128?

There are indeed Python 3.9 whls for cu128 torch.

See [https://download.pytorch.org/whl/torch/](https://download.pytorch.org/whl/torch/)

This is what I entered into python console in slicer. 4 GB download so takes a while:

slicer.util.pip\_install(“torch torchvision torchaudio --index-url [https://download.pytorch.org/whl/cu128](https://download.pytorch.org/whl/cu128)”)
