I install my application in \"project/apps/myapp\" folder. Both apps and myapp folders have init.py files(Without any of them there is module missing error)
I think this bug report (turns out it's a feature) is related to your problem.
For me the problem was resolved by importing from resume.models only, rather than apps.resume.models. So search for "from apps." in your project and replace it.
(For me, removing __init__.py or changing the PYTHONPATH caused other problems, I imagine that's common.)
