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

问题

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?

回答1:

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

回答2:

I actually had the opposite problem in that starting Ipython failed with the same error (matplotlib.is_interactive())

I had %pylab inline as part of my Ipython startup settings (~/.ipython/profile_default/startup/start.ipy) that was messing things up, and removing it cleared up the issue. This started occurring after updating my version of Ipython and Anaconda.

My thought is something similar is happening behind the scenes for you. Perhaps setting up a similar startup script to do the opposite with the code @Chao provided might work.
