Can't get attribute 'LazilyIndexedArray' error

[zonca]

Sorry I am not sure exactly what package is the cause of this error.

I am trying to read a Zarr data set from a S3 compatible object storage service with s3fs, dask and xarray.

/envs/dask/lib/python3.6/site-packages/distributed/protocol/serialize.py", line 158, in deserialize                                                                                               return f(header, frames)                                                                              File "/opt/conda/envs/dask/lib/python3.6/site-packages/distributed/protocol/serialize.py", line 20, in <lambda>                                                                                                   deserializers = {None: lambda header, frames: pickle.loads(b''.join(frames))}                         File "/opt/conda/envs/dask/lib/python3.6/site-packages/distributed/protocol/pickle.py", line 59, in loads                                                                                                         return pickle.loads(x)                                                                              AttributeError: Can't get attribute 'LazilyIndexedArray' on <module 'xarray.core.indexing' from '/opt/conda/envs/dask/lib/python3.6/site-packages/xarray/core/indexing.py'>                    

Also I noticed that Right before this error There is this other suspicious log:

distributed.protocol.pickle - INFO - Failed to deserialize

would you have any hints to point me in the right direction?

I solved this downgrading xarray to 0.10.1 as suggested here: Unidata/siphon#192
