Issue

I had a much bigger script but boiled it down to this gem of a one-liner:

import matplotlib.pyplot as plt

It compiled, although I did get the following warnings just prior to scons:

$ python3 -m nuitka --standalone --show-progress --show-scons test_matplotlib.py

Upon trying to run I get:

I think mpl-data and all it includes needs to be added to nuitka similarly to this, because manual copying works: #215

The correct (!) version of numpy does that. Either you use hinted compiles or you specify --enable-plugin=numpy=matplotlib and it should work. I sadly realized that release 0.0.4 and also the current development version did not pick up the most current plugins. If you want to try them out, copy the directory from this ZIP: hinting.zip
