Python relative import fails in Maya

Question

I am defining a new Python pipeline for Maya 2012 and I am having difficulty setting up package properly.

I have:

Prod
    __init__.py
        PackA
            __init__.py
            PAMod1.py

        PackB
            __init__.py
            PBMod2.py

PAMod1
    def a():pass

PAMod2
    def b():pass

How do I call PAMod1.b in PAMod2.b?

How do I call module with the whole name Prod.PackA.PAMod1.a() inside PAMod2.b?

Which Python Version - it __does__ make a difference? – Steve Barnes Aug 10 '13 at 17:25 — Steve Barnes, Aug 10 '13 at 17:25
@theodox all versions of Maya, up till 2013, use 2.6 – Bleeding Fingers Sep 02 '13 at 05:51 — Bleeding Fingers, Sep 02 '13 at 05:51

as long as Prod is on the python path, you can do this - the safest way, using absolute paths

# in PAMod2.py

import Prod.PackA.PAMod1

Prod.PackA.PAMod1.Function()

or (still safe, easier to type):

# in PAMod2.py

import Prod.PackA.PAMod1 as Mod1 

Mod1.Function()

You can reference a sibling package as well. This only works inside a module - you can'd do it interactively ( ie, from the maya script editor) . It's also a going to break if eather PackA or PackB moves

# in PAMod2.py

from .. import PAMod1

PAMod1.Function()

The python docs are here and this is a good SO question on the same (common) topic

for some reason, if I try the above Maya throws an error: No module named PackA.PAMod1 – Marten Zander Jun 02 '22 at 09:20
it happens when I try to import Prod.PackA.PAMod1 into __init__.py . Do you have any idea what may be the problem? – Marten Zander Jun 02 '22 at 09:21
