I believe the tests are failing because the line

        self.assertEqual([('a', 1), ('b', 1)], self.stats.derivatives_stats(local_only=True))

in test_derivatives (and the similar line in test_source_datasets) is comparing two lists that have the same elements but in a different order. The output of the test seems to indicate that in the result of self.stats.derivatives_stats, the tuple with 'b' comes first.

A solution (using set equality) would be as follows:

        self.assertEqual({('a', 1), ('b', 1)}, set(self.stats.derivatives_stats(local_only=True)))

Closing because issue fixed in #61.
