title: Jupyter not working after downgrading Python (Non Conda)
body: <p><a href="https://stackoverflow.com/questions/37244117/spyder-juypter-not-working-after-downgrading-python">There is a thread</a> on addressing how to get Jupyter to link correctly after downgrading Python, but that is referring to a Conda install. My motivation for downgrading Python is the fact that <a href="https://github.com/tensorflow/tensorflow/issues/20444" rel="nofollow noreferrer">TensorFlow is broken on Python 3.7</a>. </p>
  
  <p>After uninstalling Jupyter and downgrading Python, I receive this error. </p>
  
  <pre><code>/usr/local/bin/jupyter: /usr/local/Cellar/jupyter/1.0.0_5/libexec/bin/jupyter: /usr/local/opt/python/bin/python3.7: bad interpreter: No such file or directory
  /usr/local/bin/jupyter: line 2: /usr/local/Cellar/jupyter/1.0.0_5/libexec/bin/jupyter: Undefined error: 0
  </code></pre>
  
  <p>How do I link Jupyter and Python correctly to work properly?</p>
  
  <p>Thanks,
  Nakul</p>
