FileNotFoundError: [Errno 2] No such file or directory: 'pickled_data/tensorflow_bucket_name.pickle'

Open prep_data/image_data_guide/04b_tensorflow_training.ipynb and begin at cell In [3], where the missing pickled_data/tensorflow_bucket_name.pickle file is opened. Trace how the notebook expects that file to be created or provided, then verify the notebook no longer raises FileNotFoundError in CI.
