KeyError in keras_utils.py

[samtjong23]

I tried running on my local computer

model.fit( x_train2, y_train2, # prepared data batch_size=BATCH_SIZE, epochs=EPOCHS, callbacks=[keras.callbacks.LearningRateScheduler(lr_scheduler), LrHistory(), keras_utils.TqdmProgressCallback(), keras_utils.ModelSaveCallback(model_filename)], validation_data=(x_test2, y_test2), shuffle=True, verbose=0, initial_epoch=last_finished_epoch or 0 )

But it returned me this error

~\Documents\kkbq\Coursera\Intro to Deep Learning\intro-to-dl\keras_utils.py in _set_prog_bar_desc(self, logs)

28 def _set_prog_bar_desc(self, logs):
---> 29 for k in self.params['metrics']:
30 if k in logs:
31 self.log_values_by_metric[k].append(logs[k])

KeyError: 'metrics'

Does anyone know why this happened? Thanks.
