title: Error in node-red-contrib-machine-learning
body: <p>I'm trying to implement the most basic flow of machine learning in <code>node-red</code> using this library: <a href="https://flows.nodered.org/node/node-red-contrib-machine-learning" rel="nofollow noreferrer">https://flows.nodered.org/node/node-red-contrib-machine-learning</a>.</p>
  
  <blockquote>
    <p>This flow loads a CSV file, shuffles it and creates a training and a test partition. </p>

  <li>Python 3.6.4 or higher accessible by the command 'python' (on Linux 'python3')</li>
  <li>Numpy</li>
  <li>Pandas</li>
  <li>SciKit-Learn</li>
  <li>Tensorflow (optional: can be skipped)</li>
  </ul>
  
  <p>I opened <code>node-red</code> from <code>Anaconda</code>.</p>
  
  <p><strong>The problem:</strong></p>
  
  <p>When Clicking on "Start" node, I get the following error:</p>
