I encountered the same error, but on Windows 10, and I was able to fix it by going back to an earlier version of matplotlib (3.6.3). I guess there was something that was changed in the most recent version that breaks the code. There may be a fix for the actual code mentioned in this post, but I have not yet looked into it.

Try pip install matplotlib==3.6.3 and see if that works for you.

Many thanks for the solution. It worked for me on Linux Debian trixie.
