@mseri Not sure what else I need to pass the tests. Any suggestions? Note that I have no interest in supporting Windows so the failed CI on that platform is irrelevant as far as i'm concerned.

Hi. Thanks for publishing the package!

The Window failure is from the owl dep, and not this package, so no reason to exclude windows in the available field:

However the failures on linux should probably be fixed. E.g.,

The PR zoj613/zarr-ml#68 should fix the issue with the tests

I am working on a PR to get rid of the Owl dependency since the only functionality I use from it is very basic operations that could be implemented in a self-contained module. That should get rid of the Windows build failure. In the meantime I updated the package archive checksums to include the commit fixing the linux failures (hopefully).

Nice! All ocaml-ci is either passing or skipped now, with the exception of the name collision check, which is not flagging any relevant concerns. Let us know when you are ready for us to move forward.

[mseri]

@zoj613 if that's all right with you, we can merge
