Description
Currently, all the test suites for Python 3.6 on Linux fail on the CI for some PRs. The error is not reported on the CI run (see this one for instance).
I have setup and build ArcticDB at 134b72a on my Linux machine using Python 3.6, and running the unit test suite using:
python -m pytest python/tests/unit I get the following error:
Traceback (most recent call last):

ImportError: cannot import name '_GenericAlias'typing._GenericAlias has been introduced in Python 3.7.
Yet, it seems that some recent PR CI runs have not known this issue (for instance #328 had 3.6 Linux / unit ran successfully).
I am trying to understand what is going wrong here. Should part of the configuration be adapted?
