Error on deploying Flask application using wsgi on apache2

I am having a problem deploying a flask application on apache2 using mod_wsgi. Error log and config files follow. I always get internal server error. This is very similar to How to solve import errors while trying to deploy Flask using WSGI on Apache2 but for some reason the solution proposed there did not work here.

apache error log

sys.path.insert(0,"/var/www/bitcones")
from bitcones import bitcones as application

    ServerAdmin <my-email>
    WSGIDaemonProcess bitcones user=<my-username> group=<my-username> threads=5
    WSGIScriptAlias / /var/www/bitcones/bitcones.wsgi

<Directory /var/www/bitcones>
    WSGIProcessGroup bitcones
    WSGIApplicationGroup %{GLOBAL}
    Order deny,allow
    Allow from all
</Directory>

part of my app tree (everything is under /var/www/bitcones/)

├── bitcones
│   ├── analysis
│   │   ├── <some_files>
│   │   └── statistics
│   │   │   ├── <some_files>
│   ├── bitcones.py
│   ├── static
│   │   ├── <some static content>
│   └── templates
│       └── <my_templates>.html
└── bitcones.wsgi

This should be sufficient to figure out why I'm having this import error. If any other file/configuration is needed please ask. I'm loosing my mind.

Thanks!

EDIT: I just want to add that I was following this guide: http://flask.pocoo.org/docs/0.10/deploying/mod_wsgi/

You set the Python version that mod_wsgi uses when you install libapache2-mod-wsgi (python 2) or libapache2-mod-wsgi-py3 (python 3). I would guess you're on Python 2 from what you describe, since using python 3 is a more deliberate choice than 2. I don't think that's your problem, though. I think it's an import problem, like Graham said.

I recommend using from bitcones.analysis.statistics import purity_statistics for your import statement.
