@trupper01

There was a bug introduced in an earlier version last week. Can you try updating jcvi to the latest version?
pip install -U jcvi should get this fix. Let me know if the issue persists.

This is a common latex issue:
#543

[zhaozhaocuicui]

Okay, thank you, but I still have a question. Why does the previous Python script report an error before the LaTeX issue

[tanghaibao]

I guess when doing pip install -U it also upgrades the dependencies (including matplotlib)
This problem is really because the new version of matplotlib requires: matplotlib/matplotlib#16911

[zhaozhaocuicui]

Okay, thank you very much. I'll give it a try
