Hmm, that's odd. I believe sklearn is an indirect required dependency due to seqeval: https://github.com/chakki-works/seqeval/blob/master/setup.py#L25
But I can add it directly as well.

@tomaarsen So apparently, some old version of seqeval gets selected.

https://pypi.org/project/seqeval/#history

[sanmai-NL]

@tomaarsen I see you don't have version constraints set in your pyproject.toml.

The proper fix is to remove all transitive dependencies like scikit-learn from your distribution package's pyproject.toml, since this confuses and leads to inefficiency, and to set lower bound version constraints to all your true dependencies, like seqeval.

You can simply run pip freeze and change all the == into >=, and put those package names plus version constraint as dependencies in your pyproject.toml. And then lower the bounds further if required for compatibility.

[sanmai-NL]

@tomaarsen BTW, using Creosote you can detect unused dependencies (not used directly by your own package).

[tomaarsen]

I indeed don't have lower bounds for all dependencies - I didn't have time to look into from which versions my features started working. This is indeed not ideal.

Having said that, although sklearn is an indirect dependency according to my pyproject.toml setup, it should be a required dependency as I directly import from it in SpanMarker.
I'd like to avoid the pip freeze strategy as it will be unnecessarily constrictive. The proper fix is to set "true" minimum requirements, but as mentioned, I'm struggling to justify the time investment for that.

@tomaarsen The Python Zen: it's better to ask forgiveness than permission. Why not just require modern versions as a lower bound, and then relaxing the bound as issues are filed on this? Chances are, you will have to make minimal adjustments.
