How to get predictions from fit_generator() in Keras?

Question

Is there any way to get the predictions, something like we can get by model.predict(), of validation dataset from model.fit_generator() in Keras?

fit_generator(my_generator_train(), 
              samples_per_epoch=100, 
              nb_epoch=200, 
              verbose=1, 
              validation_data=my_generator_valid(), 
              nb_val_samples=100)

You can define your own custom callback. Look at this link.
