Description

Essentials
Changes
Return early if zero-sized dimension is used. Added test to
test_operator.py
Comments
One caveat - for the solution to work NumPy shape semantics must be used as shown in the test, otherwise the shape's zero-sized dimension of the output gets converted to 'unknown' dimension in the call to
[src.common.utils.h]::ConvertToNumpyShape
which in turn will throw an error about unknown shape. I think it's alright to use NumPy shape semantics because the input is using NumPy semantics but if not then this will require a much bigger fix.
