Problems getting PyTorch up and running on my desktop

I’m looking to get started in PyTorch on my machine. I’ve done some trivial work in TensorFlow, but their lack of support for anything other than NVidia GPUs is annoying. I have both an NVidia GPU and AMD GPU installed in my desktop, along with a CPU. I wanted to make sure I could get everything to work. To get an idea of performance, I decided to go through the standard performance tests here:

I tried running python3 install.py but that errored out with:

Error for /home/garrett/devel/benchmark/torchbenchmark/models/BERT_pytorch:
---------------------------------------------------------------------------

error: can't create or remove files in install directory

The following error occurred while trying to add or remove files in the
installation directory:

    [Errno 13] Permission denied: '/usr/local/lib/python3.10/dist-packages/test-easy-install-369467.write-test'

The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

    /usr/local/lib/python3.10/dist-packages/
<snip>

Requiring root write access to run some perf tests is dumb. At the same time, running “–help” on the install script doesn’t provide a way to specify a different installation directory, despite the error text suggesting otherwise.

So. How can I safely run some basic performance test using every combination of my GPUs and CPU for performance comparisons?
