Yes, following our policy of using the python version supported on the distros
we target at the beginning of the cycle. the Stein minimum py3 version was
Python 3.6 [0].

Dropping py2 support is currently planned for the U release cycle.

Failures on py3.7 will need to be addressed as that is one of the Python
runtimes required for Train [1].
