title: ImportError: Failed to import pydot. You must install pydot and graphviz for `pydotprint` to work
body: <p>
  I have seen similar issue but it is not solved either, so I decided to ask.</p>
  
  <p>I am trying to visualize my model in keras using</p>
  
  <pre><code>from keras.utils import plot_model
  plot_model(model, to_file='model.png')
  </code></pre>
  
  <p>First, it showed error</p>
  
  <pre><code>ImportError: Failed to import pydot. You must install pydot and graphviz for `pydotprint` to work.
  </code></pre>
  
  <p>Accordingly, I installed  pydot and graphviz through Anaconda prompt activating my environment using</p>
  
  <pre><code>conda install -c https://conda.binstar.org/t/TOKEN/j14r pydot
  conda install -c https://conda.binstar.org/t/TOKEN/j14r graphviz
  </code></pre>
  
  <p>Then, I closed spyder and reopened it. When I run code snippet, it is still showing the same error. 
  What am I missing?</p>
