599993415 MDU6SXNzdWU1OTk5OTM0MTU= 3972 Variable objects not displayable in notebook 9948595 closed 0     2 2020-04-15T03:32:13Z 2020-04-29T15:54:23Z 2020-04-29T15:54:23Z CONTRIBUTOR      

class Variable subclassesAbstractArray which has a _repr_html_ method so variable objects should display in a notebook.

But this fails with a AttributeError: 'Variable' object has no attribute 'variable':

python from os.path import join,dirname import xarray as xr ds=join(dirname(xr.__file__), 'tests/data/bears.nc') xr.open_dataset(ds).variables['cross']

Fix:

change line 186 in xarray.core.formatting_html.py:: array_section from python preview = escape(inline_variable_array_repr(obj.variable, max_width=70)) to (because obj is a variable):

python preview = escape(inline_variable_array_repr(obj.variable if hasattr(obj, "variable") else obj, max_width=70)) I can make a PR if you like.
