Saving and loading keras.callbacks.History object with np.save and np.load












0












$begingroup$


I have been saving my training history in keras as follows:



history = model.fit(X_train, Y_train, epochs=700, batch_size=128,validation_data=(X_cv, Y_cv))

np.save('./history_sim#', history)


I am then trying to load the training history from the various simulations in order to print figures like loss vs. epoch, etc. as follows:



history = np.load('history_sim#.npy')


When I try to load the training history, I am receiving the following error message:



"ValueError: Unknown metric function:precision"



I am very worried that I have lost all of the training history now. Training takes several days and I am on a bit of a time crunch. Is the data lost or is there some way to get the data from the .npy file where I have saved it?
