Any hints ?

[cknoll]

Background: As far as I know so called typing hints like kwargs:Dict={} were introduced in Python 3.6. They (normally) have no algorithmic consequence but help IDEs to give useful auto-completion proposals and type warnings during development.

As setup.py states this package requires at least Python 3.7.

In case anybody uses an OS where the Python version is too old, I would recommend using miniconda, e.g. from

https://repo.continuum.io/miniconda/ or directly from https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh.

Then one can create environments for different (and newer) python versions (which is imho not possible with packages like venv or virtualenv).

I would opt for closing this issus with label wontfix.
