What happened?

Loading an .nc file under Python 3.7 and with the latest importlib_metadata==5.0.0 doesn't work.

What did you expect to happen?

File should be loaded.

Minimal Complete Verifiable Example

```Python

Python version 3.7

import_metadata==5.0.0

import xarray as xr import numpy as np

data = xr.DataArray( np.random.rand(10, 20) ) data.to_netcdf('test.nc') xr.load_dataarray('test.nc') ```

MVCE confirmation

  • [X] Minimal example — the example is as focused as reasonably possible to demonstrate the underlying issue in xarray.
  • [X] Complete example — the example is self-contained, including all data and the text of any traceback.
  • [X] Verifiable example — the example copy & pastes into an IPython prompt or Binder notebook, returning the result.
  • [X] New issue — a search of GitHub Issues suggests this is not a duplicate.

Relevant log output

Hi, first I wanted to say that xarray is a really fantastic library, it saves so many manipulations in my work.

I was looking for a way to add a coordinate to a DataArray and attribute it to a specific dimension. I found that the following syntax was exactly what I was looking for :

python da.assign_coords(new_coordinate=('dim_to_use', values))

However, the documentation of the method was not referencing this syntax. What do you think?
