Question #707019 on Yade changed:
https://answers.launchpad.net/yade/+question/707019

Kevin Kuei gave more information on the question:
I thought maybe this could maybe be due to conflict with anaconda
already being installed on the system, so I uninstalled yadedaily, yade,
anaconda and matplotlib.

Then I reinstalled just yade.

When running the same example script, I get this message:
``
$ yade gravitydep.py
Welcome to Yade 2020.01a 
Using python version: 3.8.10 (default, May 26 2023, 14:05:08)

Running script gravitydep.py

INFO:matplotlib.font_manager:generated new fontManager
Segmentation fault (core dumped)
```

I also tried the 'pip install matplotlib==3.1.2' and still get the same
above error.

When stepping through the lines in console, the segfault is triggered on
plot.plot()
