Incompatibility with Poetry?

[akhanf]

Hello,

The dependency solver seems to go on an infinite loop when trying to add ome-zarr to a poetry project.

Can be reproduced even with just ome-zarr as the only dependency:

alik@AFI-CBS-H-15:/local/scratch/test_ome_zarr$ poetry --version
Poetry (version 1.4.2)
alik@AFI-CBS-H-15:/local/scratch/test_ome_zarr$ python3.11 --version
Python 3.11.7
alik@AFI-CBS-H-15:/local/scratch/test_ome_zarr$ poetry init

This command will guide you through creating your pyproject.toml config.

and so on.... I've let it go for a long time without success.. Maybe something in how the ome-zarr dependencies are pinned or described? I haven't dug into it in case it is obvious to anyone else.

Not urgent, as a simple workaround is to just install ome-zarr outside of poetry with just pip install ome-zarr which works fine and doesn't have any conflicts with other packages in my project.

Thanks!
Ali

Thanks for the heads up, @akhanf! I don't know off-hand why that might be, but possibly related to the pinning of #342. Can you check if installing from the main branch helps?

[akhanf]

Had the same issue with main branch, but I made some headway here I think:

Looking at the verbose output when solving it looks like it was having an issue with boto3 -- I let it run for over an hour and it finally resolved dependencies, picking up boto3==1.7.84.

So now I can get it to solve quickly if I just pin boto3<1.8.0

However, that is a really old (Aug 2018) release of boto3, so probably not a great long-term solution.. Not sure what is conflicting to cause the problem.. Assuming it would have to be something pinned in the ome-zarr-py dependencies (or test dependencies)? I see there is an open PR for #346 that might resolve all this in any case..

@akhanf, I've updated #346. Can you give it a whirl?
