title: Can't install postprocessing with pip
body: <p>I'm new to python, </p>
  
  <p>in a tutorial video they have the line <code>import postprocessing as pr</code>, </p>
  
  <p>however I receive error <code>Error: No module named 'postprocessing'</code></p>
  
  <p>But <code>pip install postprocessing</code> doesn't work, I get error <code>No matching distrubution found for postprocessing</code></p>
  
  <p><strong>Edit:</strong> apparently this may be a postprocessing.py file somewhere that wasn't released.</p>
  
  <p><strong>How do I use / install postprocessing in python?</strong></p>
