Image Classification Face Expression

I have a project image classification, but i got error when fit_generator in my model.

# number of epochs to train the NN
epochs = 50

from keras.callbacks import ModelCheckpoint

checkpoint = ModelCheckpoint("model_weights.h5", monitor='val_acc', verbose=1, save_best_only=True, mode='max')
callbacks_list = [checkpoint]

history = model.fit_generator(generator=train_generator,
                                steps_per_epoch=train_generator.n//train_generator.batch_size,
                                epochs=epochs,
                                validation_data = validation_generator,
                                validation_steps = validation_generator.n//validation_generator.batch_size,
                                callbacks=callbacks_list
                                )

and the result
