2.0.0rc1 cannot import name '_macosx' #7588
Description
Python 3.5, OS X
Launch ipython in the terminal, enter:
import matplotlib.pyplot as plt
returns
ImportError: cannot import name '_macosx'
Much bigger surprise : there is no error if I enter the command via a jupyter notebook. And the namespace is loaded in the notebook - i can tab complete plt.<tab>
And __version__ returns '2.0.0rc1' in both terminal and a notebook (I can import matplotlib without error in the terminal)
The error definitely didn't occur prior to installing 2.0.0rc1
The trace is
ImportError Traceback (most recent call last)
