[marketplace][byoc] Bring_Your_Own-Creating_Algorithm_and_Model_Package.ipynb issues

https://github.com/awslabs/amazon-sagemaker-examples/blob/master/aws_marketplace/creating_marketplace_products/Bring_Your_Own-Creating_Algorithm_and_Model_Package.ipynb

I get this error when running this notebook:`
error:CalledProcessError traceback (most recent call last) in ----> 1 get_ipython().run_cell_magic('sh', '', '\n# )`

Open aws_marketplace/creating_marketplace_products/Bring_Your_Own-Creating_Algorithm_and_Model_Package.ipynb and reproduce the reported CalledProcessError in the shell cell. Inspect the full traceback and notebook commands to identify the failing step; done means the notebook runs past that cell without the reported error.
