Inconsistent chunks when loading cube into an xarray dataset

[dzelge]

I used https://jupyterhub.earthsystemdatalab.net to generate this example. This inconsistency
will prevent exporting teh xarray.Dataset to zarr.

c = esdl.Cube.open('datacube/esdc-31d-1deg-1x180x360-1.0.2_1//')
ds = c.data.dataset()
ds.chunks
---------------------------------------------------------------------------
ValueError                                Traceback (most recent call last)
<ipython-input-36-3a43202e1c7b> in <module>()
----> 1 ds.chunks

/opt/conda/lib/python3.6/site-packages/xarray/core/dataset.py in chunks(self)
   1237                 for dim, c in zip(v.dims, v.chunks):
   1238                     if dim in chunks and c != chunks[dim]:
-> 1239                         raise ValueError('inconsistent chunks')
   1240                     chunks[dim] = c
   1241         return Frozen(SortedKeysDict(chunks))

ValueError: inconsistent chunks
