This leads to an ambiguous overall configuration. If you want to distribute this package, please make sure that 'distributed.tests' is explicitly added to the `packages` configuration field. Alternatively, you can also rely on setuptools' discovery methods (for example by using `find_namespace_packages(...)`/`find_namespace:` instead of `find_packages(...)`/`find:`).
