title: 'unexpected error' while training Object Detection model - CreateML
body: <p>I've been attempting to train an object detection model through CreateML to incorporate into my iOS application, however I am running into an issue that occurs somewhere near the 300th iteration of the training.   I receive a pop-up saying &quot;Unable to resume this training&quot;, &quot;Discard current progress or duplicate this model source to restart training&quot; along with the error message: &quot;Unexpected error&quot; in the left hand corner of the window.  Here is the <a href="https://i.stack.imgur.com/RBWAj.jpg" rel="nofollow noreferrer">screenshot</a>.</p>
  <p>Does anyone know what could possibly be causing the error and or how to fix it?  I appreciate the help!</p>
  <p>Cheers,</p>
