Is it possible to change the package names to their updated names (I think gdal conda packaging changed recently), but limit the version of the (single) package that causes the doctests to fail. In other words, if only Python or numpy makes the build fail, we could add a constraint for now.

(This PR might not need to be blocked by the three issues)

Added commit with pre-version 2 of Numpy (v 1.26.4) to see what regression Numpy 2 causes by itself.

Do we know what Python version we get with this and the changes of the PR? (To investigate Python 3.12 vs numpy 2 failures at the same time)

It all in the log: Python version under "Check installed version", packages under "Setup Mamba > micromamba list".

Seems only #4116 is caused by Numpy 2 alone.

Will try with Python 3.11 and Numpy 2.

With that setting all three files errors.

Interesting, with Python 3.11.9 with Numpy 1.26.4 the two issues #4117 and #4118 also fails. Some other dependency upgrade(s) is causing them...

Could it be the change of GEOS from 3.11 to 3.12?

Sure it must be, https://libgeos.org/posts/2023-06-27-geos-3-12-released/:

Change WKTWriter defaults output dimension to 4 and trim to ‘on’ (GH-915, Mike Taves)

I was just about to write it back here:

libgeos/geos#915

And also libgeos/geos#903 might be of concern. Maybe that's why (dimensions changed) some windows tests try to allocate an array of couple terabytes.

This is ready for review. And mergeable after #4123 is merged.

(I'm not familiar enough with the pygrass lib to address the Numpy 2 issue #4116, so for the time being I'm pinning the version to 1.x).
