Q:

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

I try to import matplotlib.pyplt in Pycharm console
import matplotlib.pyplot as plt

Then in return I get:
Traceback (most recent call last):

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? 

A:

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