ModelCheckpoint - save_best_only=True

I need explanation of save best only option of ModelCheckpoint. If I have a code like this

model.compile(optimizer='adam', loss='mse', metrics=['accuracy'])
cp = [ModelCheckpoint(filepath=path+"/model-lstmMulti", verbose=1, save_best_only=True)]        
history_callback = model.fit(X, y, epochs=350, verbose=1, callbacks=cp)

and then I want to see the accuracy of that best model:

acc_history = history_callback.history["acc"]
np.savetxt(path+"/acc_history.txt", np.asarray(acc_history))

I got the array ie. accuracy of the models of all epochs. Why I don't get only one value - accuracy of the best model?

ModelCheckpoint is a callback function used to save model file (h5) after epochs. It doesn't affect the return history of fit() method. Just use np.max to get the best acc from acc history will do your job.
