model.fit() progress bar not displaying

On Keras model.fit() I'm using verbose=1, which would supposedly show the progress bar along with other data:

costumized_xception.fit(train_generator,
                    validation_data=validation_generator,
                    epochs=2,
                    verbose=1,
                    callbacks=[es_callback, modelckpt_callback, tensorboard_callback],
                    class_weight={0:550, 1:1})

However, my PyCharm event log only shows this:

16376/Unknown - 5682s 347ms/step - loss: 0.7127
