Errors when using fathomnet with python 3.8

[mi2celis]

My laptop is running Ubuntu 20.04 with python 3.8.10

I installed fathomnet by: python -m pip install fathomnet

When I try to use it I get the following errors:

% python Python 3.8.10 (default, Mar 15 2022, 12:22:08) [GCC 9.4.0] on linux Type "help", "copyright", "credits" or "license" for more information.

Any ideas on what is going on? Thank you

If I create a virtual environment with python 3.7, fathomnet works without errors. Seems to be am issue with python 3.8

Hi @mi2celis, I just tested the python -m pip install fathomnet command on a fresh 3.8.10 environment, and it seems to run okay on all platforms. My guess is that you have an outdated typing-extensions package version installed. I recommend running

pip install --upgrade typing-extensions

to ensure you have the latest version.
