As demonstrated in this Stack Overflow question (https://stackoverflow.com/questions/59377661/python-pkgutil-get-data-disrupts-future-imports) using `pkgutil.get_data` on a module causes future imports of children modules to fail. I tracked this down to a call to `importlib._bootstrap.load` here: https://github.com/python/cpython/blob/3.8/Lib/pkgutil.py#L627 This seems to do something to sys.modules which I don't quite understand but I think it is caching the module when it shouldn't be. If I replace the linked line with `importlib.import_module(package))` it seems to work okay. |

I wouldn't use pkgutil.get_data() -- or pkgutil, period -- and instead use importlib.resources to read data files from a package (which is available as a third-party package on PyPI if you need it for older versions of Python). |

Wow, I did not know about that (probably because I've been stuck with Python3.6 for a while). Thank you! |
