matplotlib import error #59

Closed rmomizo closed 8 years ago

rmomizo commented 8 years ago

I am having trouble running matplotlib in pineapple. Each time that I import the module, I receive the following font_manager error:

/pineapple-master/build/Pineapple.app/Contents/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/matplotlib/font_manager.py:273: UserWarning: Matplotlib is building the font cache using fc-list. This may take a moment.

warnings.warn('Matplotlib is building the font cache using fc-list. This may take a moment.')
