Any guess what is wrong with this runtime error? Since I actually can import rc from matplotlib.

Answer 1

In case someone is in the same situation I am posting the answer, apparently latex was installed but matplotlib coudn't figure out the path, I rebuilt all the environnement as follows:

Updating deb repository

sudo apt-get update

This outputs latex reports on ipython

sudo apt-get install texlive-latex-extra

Finally rebuild all

sudo apt-get install dvipng
sudo apt-get build-dep python-matplotlib
