The latest pandas >= 3 moved to a dedicated string type (see documentation here) that seems to introduce an error in the compare stage in the develop branch, installed 4/3/26. From the failed file, the error appears to be happening at:
evcouplings/compare/sifts.py", line 836, in _create_mapping
n.loc[:, "j"] = n.j.astype(str)
~~~~~^^^^^^^^
which then goes on to call pandas/core/indexing.py, with the bottom-line error:
line 2163, in _setitem_single_column
raise TypeError(
f"Invalid value '{value}' for dtype '{dtype}'"
) from exc
TypeError: Invalid value '
[ '2', '3', '4', '5', '6', '7', '8', '9', '10', '11',
...
'228', '229', '230', '231', '232', '233', '234', '235', '236', '237']
Length: 236, dtype: str' for dtype 'int64'
I confirmed that reverting to pandas=2.3.3 did not throw the error, and was able to run through the mutate stage successfully. I didn't get a chance to troubleshoot with the new pandas installation though. Hope y'all are doing well!
