i think it would make more sense to do this on the IntervalArray.from_arrays method

Thanks! I will update changes in IntervalArray.from_arrays

i think putting this after the _maybe_convert_platform_interval calls would be more robust. e.g. if one is a list and the other is uint64?
Also is it just int vs uint we care about, or also e.g. int32 vs int64?

We are checking int vs unit .

is there a reason not to move this to after the _maybe_convert_platform_interval calls?

the getattr should be unnecessary. the attribute should always be there now that this is moved to after

thanks, got it. i have updated the code and removed none check for dtype.

This PR adds a check in I
ntervalIndex.from_arraysto raise aTypeErrorwhen integer arrays have mismatched signedness. Includes a unit test to verify the behavior.Please let me know if my approach or fix needs any improvements . I’m open to feedback and happy to make changes based on suggestions.
Thankyou !
