Terminate with Error loading matplotlib.pyplot

[Grillen80]

It compiles without error and the simulation runs until it terminates with throwing an instance of 'std::runtime_error'
what(): Error loading module matplotlib.pyplot!

matplotlib for python and python3 is already installed as suggested.
Im working under Linux Mint 16.04 without the docker

This StackOverflow post has a fix for this (I actually suggest the comment under the primary solution mentioning "import matplotlib as mpl then mpl.use('TkAgg').

Note that I originally got to this solution from the end of this issue, in case you're wondering how I got there.

Closing based on age, but feel free to comment again if you are still having issues / focused on this quiz.
