One oddity is that by supplying `dtype=""u8""` I see the assignment having no effect: ``` In [18]: import xarray ...: import numpy ...: da = xarray.DataArray(numpy.array([0,1], dtype=""u8"")) ...: da[0] = numpy.nan ...: print(da) array([0, 1], dtype=uint64) Dimensions without coordinates: dim_0 ``` I see the same result without the dtype arg.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,751732952
