I feel bad for the people that were missing the python modules. They were likely so close to running. The problem was that Matt installed the modules using `pip3`, but then ran the code using sudo. Had he run `sudo pip3` to install the modules, they likely would have worked.

[@PartlyXenon]

I feel like on Unix (Ubuntu 22.04 and 23.04) environments, it is best to install with apt, because even with sudo pip some of the installed packages fail to be recognised, or am I remembering this (experience) wrong?
