title: Retrieve keras model fit history afer execution interrupt
body: <p>In a jupyter notebook, I'm doing a training in keras with a line similar to</p>
  <pre><code>history = model.fit(....., epoch=100)
  </code></pre>
  <p>When I see that <code>var_loss</code> converge I break manually the execution, and obviously history is not returned.</p>
  <p>Is there a way to retrieve it? A member of model, or method, or a way to get the history object or its members?</p>
