title: Tensorflow module not found by Jupyter notebook
body: <p><strong>Problem:</strong>  Jupyter says "Module not found" when I try to import Tensorflow on Mac.</p>
  
  <p><strong>Background:</strong> </p>
  
  <ul>
  <li>Virtualenv 16.7.9 installed &amp; activated (venv)   </li>
  <li>Python 3.7.6 installed  </li>
  <li>PIP 19.3.1 installed </li>
  <li>Tensorflow 2.1.0 installed using PIP as per <a href="https://www.tensorflow.org/install/pip?lang=python3" rel="nofollow noreferrer">official install instructions</a></li>
  </ul>
  
  <p>At the command line, I can activate venv, start python3 then import tensorflow and display the tensorflow version correctly. But Tensorflow won't import from within Jupiter. And if I try to change the kernel within a Jupyter notebook, only Python3 is listed. </p>
  
  <p>On other threads, people recommend using anaconda, but I've used PIP to install Tensorflow as recommended in the above link.</p>
  
  <p>Any ideas? </p>
