Yeah, BigQuery samples won't be compatible until there are numpy, pyarrow, and pandas releases.

The failure in Kokoro CI - Python 2.7 (App Engine Standard Only) is the same as issue #6702.

There is a failure with composer/blog/gcp-tech-blog/data-orchestration-with-composer. I don't see it tracked already. I'm going to try bumping the minimum version of Flask-OpenID from 1.2.5 to 1.3.0 to see if that fixes it.
