title: how to test a deep learning model in a new dataset
body: <p>I have train and test a model. Lets name it <code>model1</code>.</p>
  
  <p>Now I want to test <code>model1</code> on a new dataset.
  So I am saving the model with <code>H5</code> and then I load the saved <code>model1</code> in a new notebook and I test it with the new dataset.</p>
  
  <p>Am I doing the procedure right?</p>
  
  <p>When should I save <code>model1</code>? 
  I see two options.</p>
  
  <ol>
  <li>After training procedure. </li>
  <li>After test procedure.</li>
  </ol>
