MacOS version of python-control crashes with matplotlib v3.0 #243
Description
While debugging pull request #242, I was getting crashes on MacOS 10.13 (High Sierra). Finally chased the problem down to matplotlib-3.0.1, which was having some problems with the backend. Documenting this here so that we can see if it is an issue for others or on other platforms.
Quick fix: set the MPLBACKEND environment variable to TkAgg
export MPLBACKEND="TkAgg"
Alternative: use matplotlib-2.2.2.

This problem seems to be gone on MacOS 10.14.3 (Mojave) and matplotlib-3.0.0 under python 3.5.

wontfix. Looks like this is still a problem on the conda-forge build for MacOS. SettingMPLBACKENDfixes it.murrayrm commentedon Dec 28, 2020
This issue seems to have been fixed. Just tested with python3.7, control-0.8.4, matplotlib-3.32 on Big Sur and all worked fine.
