From django V1.9 django.utils.datastructures.SortedDict will be removed and it is deprecated in V1.7. The similar functionality is added in collections.OrderedDict from python 2.7. Horizon code also should avoid the SortedDict class and start using the OrderedDict class. This patch replacing the SortedDict with OrderedDict.
