Fix test tests.test_model.HierarchyTestCase.test_copy on py3k #461

Closed christian-proust closed 5 years ago

christian-proust commented 6 years ago

The values returned by OrderedDict.values() is an instance of a class that cannot be copied in py3k (a list in python 2). For this reason, the following message appears :

TypeError: can't pickle odict_values objects

The solution is to first copy the OrderedDict and then get the iterator on his values.

Tested and merged. Thanks.
