Also separately I think I've discovered a related weird bug: python da1 = xr.DataArray([0], name='a') da2 = xr.DataArray([1], name='b') xr.combine_by_coords([da1, da2]) returns /xarray/xarray/core/dataarray.py:682: FutureWarning: elementwise comparison failed; returning scalar instead, but in the future will perform elementwise comparison return key in self.data /xarray/xarray/core/dataarray.py:682: FutureWarning: elementwise comparison failed; returning scalar instead, but in the future will perform elementwise comparison return key in self.data Out[5]: <xarray.Dataset> Dimensions: (dim_0: 1) Dimensions without coordinates: dim_0 Data variables: a (dim_0) int64 0 b (dim_0) int64 1 which it shouldn't do, it should have just immediately failed because there are no dimension coordinates, and otherwise single-element arrays should obviously behave the same as the other examples above. I think it's because it's reading the single element data 0 or 1 as a boolean at some point...
