Hi @anniesurla!

Thank you for your pull request and welcome to our community.

Action Required

In order to merge any pull request (code, docs, etc.), we require contributors to sign our Contributor License Agreement, and we don't seem to have one on file for you.

Process

In order for us to review and merge your suggested changes, please sign at https://code.facebook.com/cla. If you are contributing on behalf of someone else (eg your employer), the individual CLA may not be sufficient and your employer may need to sign the corporate CLA.

Once the CLA is signed, our tooling will perform checks and validations. Afterwards, the pull request will be tagged with CLA signed. The tagging process may take up to 1 hour after signing. Please give it that time before contacting us about it.

If you have received this in error or have any questions, please contact us at [email protected]. Thanks!

IMO even if it results in a more verbose notebook it's better to have all the necessary code in the notebook instead of shipping a utility file as well because this makes it harder for someone to pull the notebook out of the repo and run it independently. Notebooks should try to be as self contained as possible

@narendasan Davide suggested Tanay upload the notebook since the CLA process can take sometime. Since Tanay is all set as contributor, he will be uploading this on my behalf. You can however suggest all changes, I will make them accordingly, and when ready, Tanay will submit a new PR.
