title: Jupyter Notebook can't find modules for python 3.6
body: <p>Not sure what happened but whenever I use ipython, hydrogen (atom) or jupyter notebook can't find any of the installed modules. I know I have pandas installed but the notebook says its not found.</p>
  
  <p>I should add that when I run the script normally (<code>python script.py</code>) it does import without any errors.</p>
  
  <p>Suggestions?</p>
  
  <p>Thanks!</p>
