618985094 MDU6SXNzdWU2MTg5ODUwOTQ= 4065 keep_attrs not respected for unary operators gerritholl 500246 closed 0     2 2020-05-15T13:55:14Z 2020-10-14T16:29:51Z 2020-10-14T16:29:51Z CONTRIBUTOR      

The xarray global option keep_attrs (introduced in #2482 ) is not respected for unary operators.

MCVE Code Sample

python import xarray as xr x = xr.DataArray([1, 2, 3], attrs={"A": "B"}) with xr.set_options(keep_attrs=True): y = ~x print(x.attrs, y.attrs)

Expected Output

I expect

{'A': 'B'} {'A': 'B'}

Problem Description

I get:

{'A': 'B'} {}

I get the same for the other unary operators +x, -x, and abs(x).

Versions

Tested with latest xarray master (see below for details).
