Question

Generate and save models after training.

For some reason, the val_acc key is no longer being recognized in the Keras ModelCheckpoint and EarlyStopping callback. If used, no models are being generated and saved. It should be changed to val_accuracy

For some reason in Keras installed on my local computer (2.2.4) the available metrics are:

val_loss,val_acc, loss and acc

In the one on Compute Canada (2.3.0), the metrics are:

val_accuracy

Actually, the code mentions both:
