[BUG] Getting started-movielens 03-Training-with-HugeCTR.ipynb nb does not print out the acc and loss metrics

[rnyak]

Describe the bug
When I run the 03-Training-with-HugeCTR.ipynb notebook, the training step does not print out the accuracy and loss metrics.

We can avoid this

1. Move the following commands to another cell:

model.compile()
model.summary()
model.fit(max_iter=2000, display=100, eval_interval=200, snapshot=1900)
model.graph_to_json(graph_config_file=MODEL_DIR + "1/movielens.json")

OR

2. add the training commands to a .py file and run the following in another cell:

!python model.py

Second option might be problematic for the hugectr unit test because of !.

Steps/Code to reproduce bug
please run 03-Training-with-HugeCTR.ipynb
