导入matplotlib.pyplot会出现AttributeError: 'NoneType' object has no attribute 'is_interactive'错误。

Question

我尝试在Pycharm控制台中导入matplotlib.pyplt。

import matplotlib.pyplot as plt

然后我得到的回报是：

Traceback (most recent call last):
  File "D:\Program Files\Anaconda2\lib\site-packages\IPython\core\interactiveshell.py", line 2881, in run_code

我的 Python 版本：

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

但是当我在IPython中尝试导入matplotlib时，它可以正常工作。那么我的Pycharm控制台有什么问题吗？

我有完全相同的问题。应用程序、版本号完全相同，几乎相同的错误。不幸的是，我也没有解决方案。 - HeinzKurt

@Chao 到目前为止有什么进展吗？ - Shivendra

import matplotlib as mplmpl.use('TkAgg')import matplotlib.pyplot as plt，它可以正常工作。 - Chao

Answer 1

我遇到了完全相同的问题，升级pyCharm版本到2016.03后问题得以解决。

Answer 2

我实际上遇到了相反的问题，即启动Ipython时出现相同的错误(matplotlib.is_interactive())

我的Ipython启动设置(~/.ipython/profile_default/startup/start.ipy)中有%pylab inline，这导致了问题，删除它后问题得到解决。这是在更新Ipython和Anaconda版本后开始发生的。

我的想法是你可能也遇到了类似的问题。也许设置一个类似的启动脚本来执行@Chao提供的代码的相反操作可能会起作用。
