title: Module 'matplotlib' has no attribute 'colors'
body: <p>I am running an Anaconda installation of Python3 64bit on Windows. I have no idea how to put those words in a proper sentence, but I hope it gives enough information. I am taking an Udacity course which wants me to run <code>%matplotlib inline</code>. This gives the following error:   </p>
  
  <blockquote>
    <p>AttributeError: module 'matplotlib' has no attribute 'colors'   </p>
  </blockquote>
  
  <p>I get the same error when I run <code>from matplotlib import pylab</code>, but i get no error from <code>import matplotlib</code>.  </p>
  
  <p>I installed matplotlib as follows: <code>conda install -n tensorflow -c conda-forge matplotlib</code>.    </p>

  <p>Kind regards</p>

  <code>conda list</code> gives  </p>
