Make daemon fully python2 compatible.

[fristonio]

There are some problems when running daemon with python2 like problems with relative_imports. Make the package completely python2.7 compatible.

When I run the celery -A origamid worker -l info command, I get an Import Error saying ImportError: cannot import name 'Celery'. This happens with both Python2 and Python3.

Have you installed Celery?

If you are following these steps

$ git clone [email protected]:Cloud-CV/origami-daemon.git
$ cd origami-daemon
$ virtualenv venv
$ source venv/bin/activate
$ pip install -e .

# Start using origamid
$ origamid

# Run celery workers
# Make sure that rabbitmq-server is running
$ celery -A origamid worker -l info

# Run server
$ origamid run_server

Make sure to activate the virtual environment when running the celery worker. So open two terminals activate the virtual environment you created in both of them run a pip install -e . and then try the celery worker command. I think it should work fine.
