title: Failed to import pydot
body: <p>I was trying to print the model summary of VGG16 model and also plot the model and save it in a .png file.</p>
  
  <pre><code>from keras.applications.vgg16 import VGG16
  from keras.utils.vis_utils import plot_model
  
  #Creating the object of VGG16 model
  model=VGG16()
  print(model.summary()) 
  plot_model(model,to_file='vgg.png')
  </code></pre>
  
  <p>I also installed the below packages as suggested <a href="https://stackoverflow.com/questions/16683390/python-runtimeerror-failed-to-import-pydot">here</a>.</p>
  
  <pre><code>pip install pydot
  pip install graphviz
  pip install pydot-ng
