title: Errors with Watson Visual Recognition, training not possible
body: <p>I am trying to train two models on Watson VR. One is for object (details) recognition within a picture. The other is to estimate the class object.
  I have been able to prepare the classes of object for both models.
  However, it seems I have multiple issues with training and I am now stack. I have found <a href="https://stackoverflow.com/questions/44810422/watson-visual-recognition-training-failed">a similar post</a> in Stack Overflow but it relates to data size and type; my data are all in .jpg format and all dataset is below 250 MB.</p>
  <p><strong>Classifier:</strong>
  The classifier is the one that gives me more issues.
  Firstly, I have tried to train the model but then the server went down. The day after I have found the model &quot;trained&quot; but with errors. I basically restarted by preparing again the classes.
  All classes have at least 10-12 pictures (10 is minimum required). When I click on &quot;Train Model&quot; I receive the following error:</p>
  <p><img src="https://i.stack.imgur.com/hkJAs.png" alt="ERROR 1" /></p>
  <p>In the dashboard I am given explanation of the failed training:</p>
  <p><img src="https://i.stack.imgur.com/gDjrO.png" alt="ERROR 2" /></p>
  <p>Data size was originally about 241/250 MB, now it is 18.4/250 MB. I am not sure what brought the change.</p>
  <p>Thank you for the help!</p>
