test_inheritance_values_joins (model_inheritance_regress.tests.ModelInheritanceTest) failed:

    AssertionError('2 != 1',)

Unfortunately, tracebacks cannot be pickled, making it impossible for the
parallel test runner to handle this exception cleanly.

In order to see the traceback, you should install tblib:

    pip install tblib
