slice2py - Access outside generated folder

Python 2.7.6 development with Ice 3.5:

My 'package' structure looks something like this, I'm excluding listing most __init__ files from below:
lib+
messaging+
manager.py <-- This file includes access to the generated ice file
manager-dev.py <-- This file is for development
network+
manager.ice
manager+ <--generated
__init__.py <--generated
manager_ice.py <--generated

It doesn't seem to matter whether or not I use the 'package' directive in the slice file, unless manager-dev.py is in the same folder as manager_ice.py I get import errors. This is unacceptable for python development. Is there something I'm missing here? How can I access the generated files from another folder?

On a side note, it seems strange to me that you would generate a 'module' but then not include the generated file within that module but include it as the same level. Also, I may have other things in my __init__ files, if I use the package directive in the slice file do I have to manually add the generated __init__ elements to my current __init__ files? What if I have more than one slice file? I'm a bit confused about how this is supposed to work effectively. I hope I'm just missing something.

My slice folder looks something like this:
"python:package:lib.network" <-- I've tried it with and without the package
module manager
{
interface MessageManager
{
void func();
};
};
