keras: how to save the training history attribute of the history object

Question

In Keras, we can return the output of model.fit to a history as follows:

 history = model.fit(X_train, y_train, 
                     batch_size         


        

Answer 1

What I use is the following:

    with open('/trainHistoryDict', 'wb') as file_pi:
        pickle.dump(history.history, file_pi)

In this way I save the history as a dictionary in case I want to plot the loss or accuracy later on.
