UnknownBackend: No event loop integration for u'inline' when enable inline matplotlib in emacs python notebook

问题

I am trying to enable the python notebook in emacs. I am following the instruction from this page: https://realpython.com/blog/python/emacs-the-best-python-editor/

When I tried to do "%matplotlib inline" so that I can show the plot inline, I got the following errors:

"UnknownBackend: No event loop integration for u'inline'. Supported event loops are: qt, qt4, qt5, gtk, gtk2, gtk3, tk, wx, pyglet, glut, OSX"

My emacs is 24.4 and jupyter notebook version is 4.3

Thanks

If you are running matplotlib on osx this helped resolve my problem:

1. I upgraded to matplotlib-2.2.0 by now there is a new version 2.2.0
2. Import matplotlib
3. calling matplotlib.use('TkAgg') directly after the import of matplotlib.(comments
4. importing pyplot
5. call pyplot.plot().
6. call %matplotlib osx

I had to call %matplotlib osx instead of %matplotlib inlineone of the comment mentiond it

After that it worked.
