| 231838537 | MDU6SXNzdWUyMzE4Mzg1Mzc= | 1431 | inconsistent behavior in stack/unstack along one dimension | 11671536 | closed | 0 | 4 | 2017-05-28T01:07:09Z | 2019-05-22T21:49:13Z | 2019-05-22T21:49:13Z | NONE | I am using Ubuntu 16, python 3.6, and xarray 0.9.1 A DataArray can be stacked along one dimension, but when unstack is called a ValueError is raised. It seems that either unstack should work, or calling stack should also raise a ValueError. ```python import xarray as xr dims = ['a', 'b'] coords = {'a': range(2), 'b':range(2)} values = [[0, 0], [0, 0]] dar = xr.DataArray(values, coords, dims) stacked = dar.stack(z=('a',)) # this works unstack = stacked.unstack('z') # this raises ValueError ``` |
