Issues with importing custom Python module?

Hi,

I have a custom Python package/module with the following file structure:

• package
  – __init__.py
  – lib1.py
  – lib2.py

init.py contains imports for os, random, lib1, and lib2. lib1 contains a class, as does lib2.

In Grasshopper, I add the absolute path of the package directory to sys.path, since it’s currently not located inside the default Rhino scripts folder.

import sys

if "absolute/path/package" not in sys.path:
    sys.path.append("absolute/path/package")

import package # works fine!

As already indicated above, I’ve outsourced the importing of modules - like os, random, etc. - that I use frequently in both lib1.py and lib2.py, to __init__.py.
However, when I call classes and their methods in GHPython from lib1.py and lib2.py, I get errors, like global name 'os' is not defined, although I import os in __init__.py?

I’ve also noticed that no Python cache files (.pyc) get created, when I import package in GHPython?

Any ideas what I’m missing here?

Thanks.
