Article says "YES!"

> This new runtime allows you to take advantage of Python's vibrant ecosystem of open-source libraries and frameworks. While the Python 2 runtime only allowed the use of specific versions of whitelisted libraries, Python 3 supports arbitrary third-party libraries, including those that rely on C code and native extensions. Just add Django 2.0, NumPy, scikit-learn or your library of choice to a requirements.txt file. App Engine will install these libraries in the cloud when you deploy your app.

Yes, this runtime supports arbitrary dependencies specified via a `requirements.txt` file. If you find a library that doesn't work, please let us know. In general, anything that works using an open source Python 3.7 distribution should be supported.

Incidentally, the best way to "let us know" about bugs in GCP (App Engine or whatever else) is via the Issue Trackers, as per https://cloud.google.com/support/docs/issue-trackers (disclaimer: making this and similar processes work is my current job at Google).

Awesome!

May I follow up with:

pandas and numpy

Yup, both should work fine. Let us know if you run into issues.
