Error running the Grid Generation Basics code

After having installed everything I get the following when try to execute the code:

trying plotDomain just gives other additional errors

Can you show your full script as text (not a screenshot)?

Also, a detailed account of how you installed everything and what kind of system you're on would be useful.

Lastly, and this is confusing, the more "official" version of this repo is here:
https://github.com/pygridgen/pygridtools/

I actually installed via conda. I started by making a new environment - installed according to the instructions here: https://pygridtools.readthedocs.io/en/latest/. Then I started python and copy pasted the code from the Grid Generation Basics page. So I did not write a script of my own - I just tried the provided code.

Looks like conda is pretty far behind. I recommend uninstalling pygridtools (conda remove pygridtools?) and using pip to install from source (pip install git+https://github.com/geosyntec/pygridtools.git.

Make sure all of the deps are still in your conda environment:

pygridtools/setup.py

Line 24 in 7a3f6d9

INSTALL_REQUIRES = ['numpy', 'scipy', 'matplotlib', 'fiona', 'pandas', 'geopandas', "shapely"]

I'll try that - thanks Karsten Bolding ons. 22. okt. 2025, 19.28 skrev Paul Hobson ***@***.***>:

BTW, the conda-forge package is based on the latest release, 0.2, maybe it is time to mint a new one?

[phobson]

yeah, I'll have to remind myself how to do that

[bolding]

works with the pip install - thanks

without knowing the details I think that there is a way to initiate a conda build when making a release on Github

The bot will pick it up. We may need to do a manual one in case the versioning scheme changes though.

Let me know if you need any help automating the process here. Lately I use GitHub Actions like this one. I'm also setting PyPI Trusted Publishers. That way a new release boils down to tagging it on GH with automated release notes.
