Seems like mean_horizontal
is using sum_horizontal
, which doesn't support addition operations on dates
polars.exceptions.InvalidOperationError: add operation not supported for dtypes `datetime[Îŧs]` and `datetime[Îŧs]
It's possible to add this support by casting the columns to &DataType::Float64
(and back again after applying the mean).
This would make sense when applying mean_horizontal
on dates, but not for sum_horizontal
since all timestamps start at 1970, and results would seem wrong (for example, adding (2000, 1, 1) + (2000, 1, 1) would result in (2030, 1, 1))
I would be happy to try doing a first time contribution if I get a clear understanding of expected behavior. âšī¸ đ
