`/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/matplotlib/init.py:1357: UserWarning: This call to matplotlib.use() has no effect
because the backend has already been chosen;
matplotlib.use() must be called before pylab, matplotlib.pyplot,
or matplotlib.backends is imported for the first time.
