title: In keras how to get epoch and validation loss from model checkpoint?
body: <p>From here (<a href="https://keras.io/callbacks/#modelcheckpoint" rel="nofollow noreferrer">https://keras.io/callbacks/#modelcheckpoint</a>) you can save the best model according to the validation error by setting save_best_only.</p>
  
  <p>I know you can save the corresponding epoch and validation error by writing it to the checkpoint's file name. However, this means a lot of models could be saved and I expect this to result in memory error on my GPU.</p>
  
  <p>Is there a way to get the epoch and val loss corresponding to the final best model without having to write it in the filename?   </p>
