I was using ndenuerate with a masked array, and it seems that the mask is ignored. Is this true? If so, isn't that a bug?

This is expected behaviour: you should use the function from the “.ma" namespace “numpy.ma.ndenumerate" <https://numpy.org/devdocs/reference/generated/numpy.ma.ndenumerate.html#nump...> for skipping masked elements. By design numpy.enumerate does not skip masked elements. Stefano
