title: How to import keras.engine.topology in Tensorflow?
body: <p>I want to import keras.engine.topology in Tensorflow.
  I used to add the word tensorflow at the beginning of every Keras import if I want to use the Tensorflow  version of Keras.</p>
  
  <p>For example: instead of writing:</p>
  
  <pre><code>from keras.layers import Dense, Dropout, Input
  </code></pre>
  
  <p>I just write the following code and it works fine :</p>
  
  <pre><code>from tensorflow.keras.layers import Dense, Dropout, Input
  </code></pre>
  
  <p>But that's not the case for this specific import:</p>
  
  <pre><code>from tensorflow.keras.engine.topology import Layer, InputSpec
  </code></pre>
  
  <p>And I m getting the following error message:</p>
  
  <pre><code>No module named 'tensorflow.keras.engine'
  </code></pre>
