Dependencies - a suggestion

[davisthomas-aily]

Suggestions for the pyproject.toml that should be considerably less limiting.

Awesome, cheers for that @davisthomas-aily !

Sorry for the silence on the original PR, I've been on holiday for the end of year but have spent some evenings testing out combinations of "the big dependencies" (numpy, pandas, scipy, scikit-learn, ...) to find out where to limit the versions.

I would suggest keeping this PR open and I'll pick the updates to the smaller dependencies from here, then put those into the #433 PR if that's fine by you. I should have some time to wrap that up tomorrow. Still have a small breaking API change in scikit-learn to deal with, then we can be compatible with basically any version listed here.

Appreciate the proactive approach! And happy new year 🎉 !

Happy new year! This sounds great, I'll close this once #433 is done then :)
