CUDA/GPU Not Working.

[Johnmakuta]

I've been testing out the default test script and every time is says:

Cuda available: false
Cudnn available: false
MPS available: false

Even though I've testing in pytorch and tensorflow that my gpu is available and shown.

This is very dependent in the way you've been installing the libtorch library. If you have a working install of PyTorch 2.0.0 on which cuda/cudnn work, I would recommend using it by activating the environment and setting LIBTORCH_USE_PYTORCH=1 (more details on how libtorch can be installed on the main tch readme.
