714844298,MDExOlB1bGxSZXF1ZXN0NDk3ODU3MTA0,4485,Handle scale_factor and add_offset as scalar,500246,closed,0,,,3,2020-10-05T13:31:36Z,2020-10-16T21:20:14Z,2020-10-11T20:06:33Z,CONTRIBUTOR,,0,pydata/xarray/pulls/4485,"The h5netcdf engine exposes single-valued attributes as arrays of shape
(1,), which is correct according to the NetCDF standard, but may cause
a problem when reading a value of shape () before the scale_factor and
add_offset have been applied.  This PR adds a check for the dimensionality
of add_offset and scale_factor and ensures they are scalar before they
are used for further processing, adds a unit test to verify that this
works correctly, and a note to the documentation to warn users of this
difference between the h5netcdf and netcdf4 engines.

 - [ ] Closes #1663 

Note: I'm not sure how to test for this, as I think existing tests should be already failing due to this.  In fact, when I run `nosetests` on my system I get 123 skips, 29 errors and 2 failures, none of which are related to my addition, so there must be something wrong on my system.

I did not try the flake8 test and I think new documentation is exaggerated in this case.
