ValueError when reading the feature mask

[tripledes]

Trying to run gpu-utils with the following environment:

• Running on a venv
• Installed from pypi
• Python version 3.9.0
• Kernel: 5.10 (liquorix)
• OS: Debian/testing

I get the following error:

Traceback (most recent call last):

I get the same error using the packaged version for Debian testing (bullseye).
