Do you have any idea what causes this issue? Happened when I compiled on Ubuntu 16 for aarch64 and running on 18.

Traceback (most recent call last):

That to me looks like an environment problem.

Looks like it should solve it.

Otherwise, I can force it to not have the interactive mode part (which isn't needed anyway) and force it to use agg with

matplotlib.use('Agg')

If the first solution isn't viable, let me know, and i'll modify the code.

Is this still an issue?

Yes. We should get rid of this xwindow thing.
