title: keras_vggface: No module named 'keras.engine.topology'
body: <p>There are several tutorials online that import a VGGFace model from keras_vggface like this:</p>
  <pre><code>from keras_vggface.vggface import VGGFace
  </code></pre>
  <p>However, I get the following error:</p>
  <pre><code>ModuleNotFoundError: No module named 'keras.engine.topology'
  </code></pre>
  <p>This problem happens on my local machine, but also on Google Colab after installing <code>keras_vggface</code> with</p>
  <pre><code>!pip install keras_vggface
  </code></pre>
