Good catch! It seems like we have 3.5.3 on Toolforge. Being a light user of pip, I have no clue how to force installation of an earlier version of the python module. Any advice on that?
You can use `pip install <package_name>==<version>` to install an exact version. See https://pip.pypa.io/en/stable/reference/pip_install/#requirement-specifiers for a bit more detail.
Your particular problem sounds like a bug in the upstream packaging as well. The version of the library that requires f-strings should have been marked as requiring Python >= 3.6 in pypi. That would have let pip figure out that it needed to install a different version of the library for the Python 3.5 runtime.
I would like to get support for Python 3.7 added to the Toolforge Kubernetes environment "soon". It should be relatively easy once we have a Debian Buster base container to extend.
