This is exactly how it’s supposed to behave for namespace packages. The *.pth file will take care of providing info about your namespace to the python importer. > Instead there’s just a dir with "foo/bar/__init__.py" and > "foo/blah/__init__.py". These are regular packages. Hence they preserve their __init__.py. Hope this helps. Regards, Zvezdan > I will try to look in the "wheel" side of things next I guess.
