After some experimentation it turns out you have to provide some context for
__import__() to determine the absolute location of the requested module. The
required bit of information is the current module's __name__ attribute which
you can provide via the globals parameter:
def import_segmentation(name):
return getattr(__import__("segmentation." + name, level=2,
globals=globals()), name)
