unable to load app 0 (mountpoint='uwsgi') (callable not found or import error)

I'm trying to get uwsgi to work with python, but nomatter what i do it cant load my app.. i get this error: 

unable to load app 0 (mountpoint='uwsgi') (callable not found or import error)

uwsgi.ini:

[uwsgi]
http = 0.0.0.0:8000
module = uwsgi
callable = application

uwsgi.py:

def application(env, start_response):
start_response('200 OK', [('Content-Type', 'text/html')])
return ["Hello!"]

directory structure is like this:

/config/
.... __init__.py
.... uwsgi.ini
.... uwsgi.py

I cant figure out what is wrong. I have been through several examples, articles and answers on this site and nothing has solved the problem for me.. ive tried command line initialization and calling the .ini, I'm at a loss as to what to do, uwsgi seems to find uwsgi.py because I don't receive the module not found error, but for some reason it is unable to load. the stripped down command line init was this command:

uwsgi --ini uwsgi.ini

but I have tried several variations, though obviously none that have worked.

here is the error in its entirety:

check the ownership of the files. uwsgi will run with an unprivileged user. make sure that the www-data or whatever user you use has read access for wsgi.py

This is configuration that works for me, wsgi.py:

def application(env, start_response):
    start_response('200 OK', [('Content-Type', 'text/html')])
    return ["Hello!"]

and uwsgi.ini:

[uwsgi]
http = 0.0.0.0:8000
module = wsgi
callable = application

and start it like this:

uwsgi --ini uwsgi.ini
