title: No module named 'tensorflow_examples' after installing
body: <p>In my Notebook's first cell, I wrote :</p>
  <pre><code>!pip install git+https://github.com/tensorflow/examples.git
  !pip install -U tfds-nightly
  </code></pre>
  <p>On the next cell :</p>
  <pre><code>import tensorflow as tf
  from tensorflow_examples.models.pix2pix import pix2pix
  </code></pre>
  <p>But it gives me : <strong>ModuleNotFoundError: No module named 'tensorflow_examples'</strong></p>
  <pre><code>Notebook - version : 6.0.3
  Tensorflow - version : 2.0.0
  </code></pre>
  <p>Do I need to install additional some modules ?</p>
  <p>Here is the pip install log :</p>
