import matplotlib.pyplot gives AttributeError: 'NoneType' object has no attribute 'is_interactive'

Question

I try to import matplotlib.pyplt in Pycharm console

import matplotlib.pyplot as plt

Then in return I get:

My python version：

Python 2.7.12 |Anaconda 4.2.0 (64-bit)| (default, Jun 29 2016, 11:07:13) [MSC v.1500 64 bit (AMD64)] on win32

But when I try to import matplotlib in Ipython, it works. Is there something wrong with my Pycharm console?

I faced the exact same problem and proble is resolved after i upgraded pyCharm to 2016.03 version.
