This works fine for me::

    $ mkdir --parents app/module/
    $ touch app/module/__init__.py
    $ printf "import b\n" > app/module/a.py
    $ printf "def foo(): pass\n" > app/module/b.py
    $ printf "from module import a\n" > app/test.py
    $ find .
    .
    ./app
    ./app/module
    ./app/module/__init__.py
    ./app/module/a.py
    ./app/module/b.py
    ./app/test.py

    $ python app/test.py

I get no errors; the code appears to run fine. Perhaps the scenario is
not exactly as you describe?
