title: No module named 'PIL'
body: <p>I'm running into an error where when I try </p>
  
  <p><code>from PIL import Image, ImageFilter</code></p>
  
  <p>in a Python file I get an error stating <code>ModuleNotFoundError: No module named 'PIL'</code>.</p>
  
  <p>So far I've tried uninstalling/reinstalling both PIL and Pillow, along with just doing <code>import Image</code>, but the error keeps on occurring and I have no idea why. All the solutions I've found so far have had no effect on my issue. </p>
  
  <p>I'm running Python 3.5 on Ubuntu 16.04</p>
