Dependency conflict with fesom_icb_pism plugin

[FinnHeu]

Hi there,

it seems there is a dependency conflict with the packaging python library when installing the fesom_icb_pism plugin.

The dependency conflict occurs due to a version pinning issue in setup.py (l. 27):

1. esm_tools requires packaging==21.3 (pinned version)
2. The fesom_icb_pism plugin (installed when with_icb: True in fesom-2.6.yaml (l. 278-281) depends on pyfesom2
3. pyfesom2 requires jupyter, which brings in ipykernel and jupyter-server
4. Both ipykernel and jupyter-server require packaging>=22
5. At runtime, when pkg_resources tries to load the plugin, it detects the version conflict and raises ContextualVersionConflict

Is there a particular reason the packaging library is pinned? When I modified setup.py and allowed more recent versions packaging>=21.3 everything was working fine again.

Best,
Finn

I am working on branch feat/awiesm3-v3.4-co2 but the version conflict also appears in the latest release.

Hi @FinnHeu, thanks for reporting this. The reason for pinning is that dependencies stay under the same version and only change if we need to, or if we decide to update dependencies.

I'll change the packing version to a newer one and see if everything works smoothly.

Were you able to resolve the problem manually or do you need help for a provisional solution?

Hey @mandresm,

great, thanks for the quick reply.
I solved it by simply manually updating my setup.py to contain packaging>=21.3. This patch works fine for me until this is resolved in the release, no need to hurry - I have a working setup.

Cheers

Thanks for confirming that you have a workaround :)

Hi @FinnHeu, I have merged a PR with updates in the dependencies, including a minor requirement of version 24.0 of packaging. Please, let me know if that sorts out the problem for you and feel free to close the issue in that case :)
