Description
I don't know whether doing this is supposed to be supported, but if it isn't the error message could be improved to alert the user that nanstd and dtype=object are incompatible.
Reproducing code example:
import numpy
numpy.nanstd(numpy.array([71, 98.0, 80, 93, 57, 46], dtype=object))Error message:
