title: Python3.6: error installing Pylab
body: <p>There are similar questions posted on Stackoverflow that did not seem to work for me.  I am trying to install the pylab module for Python.  I am using OSX.  I have Python 2.7, 3.6, and 3.7 installed and have been running IDLE from 3.6.  I also installed Anaconda.  It looks like I have the modules and libraries I need here:</p>
  
  <pre><code>/Users/[username]/anaconda3/lib/python3.6/site-packages/matplotlib
  </code></pre>
  
  <p>There is also a <em>pylab.py</em> in that same site-packages directory.
  But when I run a simple Python program with:</p>
  
  <pre><code>from pylab import plot, show
  </code></pre>
  
  <p>I get this error message:</p>
  
  <pre><code>Traceback (most recent call last):
    File "/Users/[username]/Desktop/Python/graph.py", line 1, in &lt;module&gt;
      from pylab import plot, show
  ModuleNotFoundError: No module named 'pylab'
  </code></pre>
  
  <p>Not sure what I am doing wrong.</p>
