I am not totally sure if the problem started when upgrading to Big Sur:
I use anaconda distribution and when I use python 2.7 and plot (plot or scatter) using matplotlib, python closes and shows this message "zsh: segmentation fault python"
If instead I use Spyder 3 compiler, the message doesn't show up but neither the graph, it doesn't show anything at all.
The code can be as simple as:
import matplotlib.pyplot as plt
lx=[1,2]
ly=[1,2]
plt.scatter(lx,ly)
plt.show()
I have uninstalled all anaconda and installed again and now the message is:
"Fontconfig warning: ignoring UTF-8: not a valid region tag
zsh: segmentation fault python"
This only happens with python 2.7, and I believe it started when making some updates on Big Sur OS. When I open python 3.8 or 3.7 (or Spyder 4) there is no problem, all works fine.
Anaconda and Mac OS itself has recommended many times to upgrade to python 3.8, but I have worked so long with 2.7 and wish if I could stay some more time with my original codes and programs. \
I would like to know if this problem is because of the OS upgrade or if it is something else.
PD: I have updated matplotlib with Conda, everything looks updated (matplotlib: 2.2.3) Also have uninstalled and reinstalled anaconda. It doesn't work with python 2.7 on Big Sur
