Environment

Cause

The issue is caused by the lack of compatibility between the versions used in the networkx package and the pydot package.

Solution

pip3 install pydot -U
pip3 install networkx -U
$ pip3 list | grep -e networkx -e pydot
networkx                             3.4.1
pydot                                3.0.2
