Import matplotlib.pyplot gives AttributeError: object 'NoneType' does not have attribute 'is_interactive'

Question

I am trying to import matplotlib.pyplt in Pycharm console

import matplotlib.pyplot as plt 

Then in return I get:

 Traceback (most recent call last): File "D:\Program Files\Anaconda2\lib\site-packages\IPython\core\interactiveshell.py", line 2881, in run_code exec(code_obj, self.user_global_ns, self.user_ns) File "<ipython-input-5-eff513f636fd>", line 1, in <module> import matplotlib.pyplot as plt File "D:\Program Files\JetBrains\PyCharm Community Edition 2016.2.3\helpers\pydev\_pydev_bundle\pydev_import_hook.py", line 21, in do_import module = self._system_import(name, *args, **kwargs) File "D:\Program Files\Anaconda2\lib\site-packages\matplotlib\pyplot.py", line 2512, in <module> install_repl_displayhook() File "D:\Program Files\Anaconda2\lib\site-packages\matplotlib\pyplot.py", line 165, in install_repl_displayhook ip.enable_gui(ipython_gui_name) File "D:\Program Files\JetBrains\PyCharm Community Edition 2016.2.3\helpers\pydev\_pydev_bundle\pydev_ipython_console_011.py", line 125, in enable_gui raise UsageError("%s" % e) UsageError: Invalid GUI request 'qt5', valid ones are:['pyglet', 'osx', 'none', 'gtk3', 'tk', 'qt', 'glut', 'gtk', 'qt4', 'wx'] Traceback (most recent call last): File "D:\Program Files\Anaconda2\lib\site-packages\IPython\core\events.py", line 74, in trigger func(*args, **kwargs) File "D:\Program Files\Anaconda2\lib\site-packages\matplotlib\pyplot.py", line 147, in post_execute if matplotlib.is_interactive(): AttributeError: 'NoneType' object has no attribute 'is_interactive' Error in callback <function post_execute at 0x0000000008AAD438> (for post_execute): 

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?

Answer 1

I ran into the same problem and the problem was resolved after upgrading the pyCharm version to version 2016.03.

Answer 2

I really had the opposite problem in that the launch of Ipython failed with the same error (matplotlib.is_interactive())

I had the %pylab inline part of my Ipython startup settings ( ~/.ipython/profile_default/startup/start.ipy ) that was messy, and deleting it fixed the problem. It started after updating my version of Ipython and Anaconda.

My thought is something like this is happening behind the scenes for you. Perhaps creating a similar script run to execute the opposite code with the provided @Chao code might work.
