I just tried to install py3grads in a fresh conda environment. I ran python setup.py install and there's the output I saw, py3grads was not installed when it was done.

$ python setup.py install

As a work-around I remade my conda environment with setuptools=58.2.0 (last version before those deprecation warnings), this also installed Python 3.9 and this time the install ran successfully. I'm not sure if it was setuptools itself that caused this or something else, either way it seems py3grads needs an updated way to install in newer environments.

Thanks for the report -- the ecosystem is leaving setup.py behind. I've switched this project to using pyproject.toml as of the v2023.6.30 tag that I just pushed. This should allow installation via pip install git+https://github.com/meridionaljet/py3grads

Thank you! I verified this solution works by spinning up a new conda env and the above pip command worked. Python 3.11, setuptools 68.0.0.

This package gets some good use, thanks for keeping it alive!
