1.6.0: pytest is failing

Comienza con tests/cloudpickle_test.py y tests/test_backward_compat.py, centrándote en las importaciones relativas que aparecen en los errores de collection. Ejecuta el comando de pytest indicado con el PYTHONPATH empaquetado y, después, verifica que ambos módulos de prueba se recopilen correctamente y que la ejecución completa de las pruebas termine sin errores de importación.

I'm trying to package your module as rpm packag. So I'm using typical in such case build, install and test cycle used on building package from non-root account:

• "setup.py build"
• "setup.py install --root </install/prefix>"
• "pytest with PYTHONPATH pointing to sitearch and sitelib inside </install/prefix>

May I ask for help because few units are failing:
