Pre-requisites for ROCm support for pytorch on Windows

This is my second attempt posting this question. I think I put it in the general software topic originally which is probably the wrong place.

Is there any documentation on what is actually required to use the AMD GPU accelerated version of PyTorch with Siril scripts?

I’ve tried multiple Radeon and Radeon Pro driver versions, I have ROCm 7.1 installed from the HIP SDK, but I cannot get the 1.4.2 GPU Manager to report anything other than amd_other for the graphics card detected and it always reports “rocm compatible: false” even though I have an RX 9070.
Do I need to install WSL? Do I need to install all the AI addons that come with the AMD driver (all 30GB of it!!), or is just the driver itself enough?

Any help would be appreciated
