Retrieve keras model fit history afer execution interrupt

Question

In a jupyter notebook, I'm doing a training in keras with a line similar to

history = model.fit(....., epoch=100)

When I see that var_loss converge I break manually the execution, and obviously history is not returned.

Is there a way to retrieve it? A member of model, or method, or a way to get the history object or its members?

@Mquinteiro Try using a callback: https://keras.io/callbacks/. You could set the callback to terminate when the model is no longer improving (keras.callbacks.EarlyStopping) and then access the best model (save_best_only = True), or you could have the callback save checkpoints after each epoch (keras.callbacks.ModelCheckpoint) which you can access after manually stopping the execution.
