The main branch fails with `skip_reason` not defined

I don't know how this got passed the CI, but it failed on main:

               except nvml.NoPermissionError:
>                  skip_reasons.add(f"nvmlDeviceSetComputeMode requires root for device {device}")
                   ^^^^^^^^^^^^
E                   NameError: name 'skip_reasons' is not defined

It seems to be an implicit merge conflict between #1510 and #1515 that slipped from being caught by git.

I'm looking into this right now, because it's blocking updating our branch for QA testing. I already reproduced the error locally (bare-metal Ubuntu). Working on a fix.
