WebOnto my problem: The Keras callback function "Earlystopping" no longer works as it should on the server. If I set the patience to 5, it will only run for 5 epochs despite specifying epochs = 50 in model.fit(). It seems as if the function is assuming that the val_loss of the first epoch is the lowest value and then runs from there.
