[JOSS] Pip installation failure.

Hi,

I tried to install the package via pip on ubuntu and encountered the following error:

  note: This error originates from a subprocess, and is likely not a problem with pip.
error: subprocess-exited-with-error

Is it possible that the requirements are too strict?
One thing that might help is setting up a github action (or other CI) that tests the pip installation for all intended operating systems.

Hmmm, interesting. Our CI pipeline implements a 'deploy' job testing exactly this, but only using the python:3.9.14 Docker image that runs on Debian. I'll add testing pipelines in other OS and troubleshoot

Dear @edeno,

I just pushed a new version to PyPI, with a much less restricted set of requirements that works fine across different OS (Ubuntu included). I tested it with Python 3.10.6 in Ubuntu 23.10.

Feel free to retry pip install (preferable in a new environment) and let me know if you still have problems. I'll close the issue for now!

Also confirming pip installation was successful.
