Error at the installation on Fedora/Debian and python 2.7

The package is using several libraries that need to be compiled in order to work properly as they aren’t 100% python. If you get an error such as

gcc: error: /usr/lib/rpm/redhat/redhat-hardened-cc1: No such file or directory

You can try to resolve the issue by installation the package redhat-rpm-config, or build-essential on Debian based flavours.

tkinter.TclError: no display name and no $DISPLAY environement variable

If for some reasons you run this program on machine without XWindow, you will most probably encounter this error. It exists a workaround by specifying to Matplotlib which backend you want to use. Most probably you’ll use the default backend called Agg. In order to do that, you need to edit the matplotlibrc file located on GNU/Linux in ~/.config/matplotlib/matplotlibrc.

You will need to edit or add the following line:

backend   : Agg

If you don’t use GNU/Linux or want further information about this particular setup, I advise you to visit the Matplotlib documentation.
