301888608 MDU6SXNzdWUzMDE4ODg2MDg= 1954 ds.to_zarr error on creation 9453271 closed 0     8 2018-03-02T20:05:32Z 2018-03-06T19:00:28Z 2018-03-06T19:00:28Z CONTRIBUTOR      

Creating just a sample dataset: data = xr.DataArray(np.random.randn(2, 3), coords={'x': ['a', 'b']}, dims=('x', 'y')) ds_test = xr.Dataset({'foo': data, 'bar': ('x', [1, 2]), 'baz': np.pi}) print(ds_test) ds_test.to_zarr(store='foo.zarr', mode='w')

Writing this locally. This generates a .zgroup and .zattrs file, but then fails out with, AttributeError: 'Attributes' object has no attribute 'put'. Tried on a couple machines and I get the same error each time.

Run on:

MacOS 10.13.3 CentOS Linux release 7.4.1708 (Core)

```
