Loading an *.nc* file under Python 3.7 and with the latest [importlib_metadata](https://github.com/python/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](https://mybinder.org/v2/gh/pydata/xarray/main?urlpath=lab/tree/doc/examples/blank_template.ipynb), returning the result. - [X] New issue — a search of GitHub Issues suggests this is not a duplicate. ### Relevant log output ```Python Traceback (most recent call last): File ""xarray_bug.py"", line 7, in xr.load_dataarray('test.nc') File ""/home/etienne/anaconda3/envs/py37/lib/python3.7/site-packages/xarray/backends/api.py"", line 267, in load_dataarray with open_dataarray(filename_or_obj, **kwargs) as da: File ""/home/etienne/anaconda3/envs/py37/lib/python3.7/site-packages/xarray/backends/api.py"", line 666, in open_dataarray **kwargs, File ""/home/etienne/anaconda3/envs/py37/lib/python3.7/site-packages/xarray/backends/api.py"", line 479, in open_dataset engine = plugins.guess_engine(filename_or_obj) File ""/home/etienne/anaconda3/envs/py37/lib/python3.7/site-packages/xarray/backends/plugins.py"", line 110, in guess_engine engines = list_engines() File ""/home/etienne/anaconda3/envs/py37/lib/python3.7/site-packages/xarray/backends/plugins.py"", line 105, in list_engines entrypoints = entry_points().get(""xarray.backends"", ()) AttributeError: 'EntryPoints' object has no attribute 'get' ``` ### Anything else we need to know? - Only with **importlib_metadata==5.0.0** - Doesn't works with Python **3.7** but it works with **3.9** - Similar problem for [flake8](https://github.com/python/importlib_metadata/issues/406) repo. - They solved it by imposing a specific version for python versions under 3.8 : https://github.com/PyCQA/flake8/blob/2c1bfa1f3d85e4d94ebc3b6d601d454a09d8043e/setup.cfg#L44 ### Environment

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](http://xarray.pydata.org/en/stable/generated/xarray.DataArray.assign_coords.html#xarray.DataArray.assign_coords) of the method was not referencing this syntax.
