title: Can't import plot_model from keras.utils?
body: <p>When I run this line in my code,</p>
  <p><code>from keras.utils import plot_model</code></p>
  <p>I get the following:</p>
  <pre><code>&quot;ImportError: cannot import name 'plot_model' from 'keras.utils' (/usr/local/lib/python3.7/dist-packages/keras/utils/__init__.py)&quot;
  </code></pre>
  <p>When I went to bed last night it was working. This morning it throws an error. What happened and what should I do? Thank you.
  Any suggestion would be appreciated</p>
