@sdgilley - still need your approval/sign off before this can be moved forward.

Also, NOTE - @raoberman - that this PR adds Jupyter notebook calls and because of that, the commits will need to be moved into the private repo for staging before they can be merged. @balapv @sdgilley - can you do this?

let us know if you'd like our assistance.
#hold-off

The notebook changes have not been merged - Azure/azureml-examples#2429 has some build errors that you'll need to resolve first. Can you coordinate with @balapv to get these fixed and merged?

[raoberman]

@sdgilley @balapv the changes were merged in a different PR, and the tags are in the notebook metadata. not sure why they're not being detected.

@raoberman - I merged your changes in a separate PR. But am reversing the change to the quickstart this morning. The quickstart uses a curated environment, which does not include the required package. The purpose of the quickstart is to get the basics up and running as quickly as possible; it's not the right place to introduce custom environments. So, we can leave your change in the how-to article, but not in the quickstart.
