  <pre><code>from IPython.display import Image  
  import pydotplus
  dot_data = tree.export_graphviz(regr, out_file=None, feature_names = X_train.columns.values ,filled=True)

  <p><strong>Solution</strong>
  Is there another environment that actually has this module installed?
  OR
  Is there a way to install/add this python module to the existing runtime?</p>
