Creating a conda env with "all" radar packages

I have been trying to create a one single conda environment that would include wradlib, arm_pyart, pysteps and other related packages (shapely, scipy, cartopy and so on), but have not been able to do it as the solver keeps dying. I have an env with wradlib and pysteps on it, but it took like 20 tries with different order of installations, but maybe there is a better way to look at it? So far I have pretty much only tried creating new envs from scratch, because later installations usually fail with conda (or take 8 hours of solving and then fail).

First, is it a weird question (to have all the packages in one env)? I.e. maybe I’m just overthinking the problem…!?
Are there any pointers how to make the env creation process less painful? For example use something different than conda?
Any other good advice regarding this issue?

Thanks in advance!

Hi @jorahu,

that’s a common issue, and I’m trying this every once in a while. You can have a look at the openradar workshop repos (eg. GitHub - openradar/ams2025 or GitHub - openradar/erad2024: Repo for the ERAD 2024 Open Radar Short Course) for efforts to get most packages into one environment.

As long as all dependencies are somehow within conda-forge, this seems like it should work. But for some packages, carrying outdated dependencies in their conda-recipes, this might lead to unsolvable environments.

It might also depend on which installer you are using (conda/mamba, miniconda/miniforge). I’m using conda-forge | community-driven packaging for conda with mamba.

If packages need to be build from scratch or just provide wheels also could lead to version clashes along the road.

I think this was discussed already at some point at developer meetings. It would be nice, if we could somehow setup a CI run, somewhere in an openradar repo, which just verifies the installation process for our community packages.

HTH,
Kai
