Limiting compatibility with numpy 2.1

[hmaarrfk]

Comment:

Is it worth limiting compatibility with numpy 2.1?

On my personal package, I already limit to numpy 1.X so I don't hit it so much, but I feel like some others might be hitting https://github.com/pydata/xarray/pull/9403

We personally hit it and added monkey patches around it....

looks like the reason we don't see that in CI (except upstream-dev) is that a dependency already pins to numpy<2.1

hmmm, i'm not sure how my previous environments were working with numpy 2.1 + xarray

I tried:

mamba create --name xr xarray>=2022 numpy=2.1 --channel conda-forge --override-channels

and its not resolving.... so maybe something changed....

Hmm, i just created a fresh envrionment and I noticed my monkeypatching code (that fixex the issue referenced) got triggered (i print a warning).

$ mamba list | grep -E "(xarray|numpy)"
numpy                     2.1.1           py310hd6e36ab_0    conda-forge
xarray                    2024.9.0           pyhd8ed1ab_0    conda-forge

seems to be compatible....

$ mamba create --name xr "xarray>=2024" "numpy>=2.1.0" python=3.10 --channel conda-forge --override-channels

Looking for: ["xarray[version='>=2024']", "numpy[version='>=2.1.0']", 'python=3.10']
