title: from PIL import Image failed on Python3.6
body: <p>I'm new to <a href="https://www.python.org/" rel="nofollow noreferrer">Python</a> and I have a problem with <a href="https://pypi.org/project/Pillow/" rel="nofollow noreferrer">Pillow</a> (as many people before me). </p>
  
  <p>Running the command below:  </p>
  
  <p><code>from PIL import Image</code></p>
  
  <p>causes a known error: </p>
  
  <p><code>ModuleNotFoundError: No module named 'PIL'</code></p>
  
  <p>The problem occurs when I try to run it with Python 3.6, everything works fine with Python 3 however I have to use version 3.6 in my project.</p>
  
  <p>Pillow version: 4.3.0, so it is compatible with this Python version.</p>
  
  <p>Why does this not work on the newer version? </p>
