This is a design decision by the cime (whatever that is) developers. A package does not magically import all of its subpackages. That's a good, because otherwise large packages like SciPy would take forever to import (like NLTK does).

Some packages, like os.path, NumPy and NLTK will import submodules, but they do so explicitly. If you want this to happen in your own module, do

# __init__.py import .submodule
