Comment:
There are tests, but not in the pypi tarball. I switched the source to github and the tests are there, but they require [cloudpickle](https://pypi.org/project/cloudpickle/) which we don't package. `python3-joblib` includes files related to cloudpickle, but it doesn't satisfy the requirement.
