iPython, Jupyter -> AttributeError: 'module' object has no attribute 'cbook'

Question

I am a beginner at programming and I am working on an online course which uses ipython and jupyter notebook. I am working with Mac OS 10.13.3.

I have tried importing matplotlib as follows,

import matplotlib.pyplot as plt
%matplotlib inline

However, the following error is being generated.

--------------------------
Traceback (most recent call last) <ipython-input-30-385145dcc870> in <module>()
----> 1 import matplotlib.pyplot as plt
      2 get_ipython().magic(u'matplotlib inline')

/Users/Varshil/anaconda/envs/gl-env/lib/python2.7/site-packages/matplotlib/pyplot.py in <module>()
     27 from cycler import cycler
     28 import matplotlib
---> 29 import matplotlib.colorbar
     30 from matplotlib import style
     31 from matplotlib import _pylab_helpers, interactive

     31 import matplotlib as mpl
---> 32 import matplotlib.artist as martist
     33 import matplotlib.cbook as cbook
     34 import matplotlib.collections as collections

/Users/Varshil/anaconda/envs/gl-env/lib/python2.7/site-packages/matplotlib/artist.py in <module>()
      9 import numpy as np
     10 import matplotlib
---> 11 import matplotlib.cbook as cbook
     12 from matplotlib.cbook import mplDeprecation
     13 from matplotlib import docstring, rcParams

AttributeError: 'module' object has no attribute 'cbook'

It would be of great help if someone could help me solve this issue. I have tried looking up online but have found no successful leads.

Something went wrong when installing matplotlib. Try to uninstall and reinstall again. — ImportanceOfBeingErnest

@ImportanceOfBeingErnest Initially, I installed the whole package using graph lab create launcher. So I uninstalled the graph lab launcher and installed it again. I checked after uninstallation whether matplotlib exists and it did not. However the issue still remains. — Varshil Anavadia

I have tried finding which matplotlib has been imported by typing... import imp imp.find_module("matplotlib") This is the result. (None, '/Users/Varshil/anaconda/envs/gl-env/lib/python2.7/site-packages/matplotlib', ('', '', 5)) Can someone explain what this means? — Varshil Anavadia

This is because you are using old version of matplotlib.

Those who are using GraphLab Create, first activate virtual environment:

source gl-env/bin/activate

Now upgrade matplotlib:

pip install -U matplotlib

Output:

Found existing installation: matplotlib 1.5.1 Uninstalling matplotlib-1.5.1: Successfully uninstalled matplotlib-1.5.1 Successfully installed matplotlib-2.1.2

Restart iPython/Jupyter.

If you are on Mac, you might get the following error:

RuntimeError: Python is not installed as a framework. The Mac OS X backend will not be able to function correctly if Python is not installed as a framework.

Create a file ~/.matplotlib/matplotlibrc there and add the following code: backend: TkAgg

Again restart iPython/Jupyter.
