Debug Flask with complicated project structure Follow

I'm new to debugging flask with pycharm, so hopefully nothing I ask is too trivial.

I have two files

code/__init__.py and code/runserver.py

In the __init__ file is the where my Flask app is initialized meaning that is where the statement :

app = Flask(__name__) 

prettyPrint();
occurs.

In the runserver.py file is where I have the statement

if __name__ == '__main__':
    main()

prettyPrint();


The runserver imports the app in the following manner :

from code import app, __app_name__, __version__

prettyPrint();

Inside of the main function are a number of parser.addoption commands and then ultimately

def main():
parser = OptionParser()
    parser.add_option("-d","--debug",action="store_true",default=app.config.get('DEBUG',True),dest="debug",help="Turn on debugging")

(options,args) = parser.parse_args()

app.run(debug=options.debug,host=options.address,port=options.port)

prettyPrint();


In this case what would my entry point for debugging the application be?
I assumed it would be runserver.py but when I attempt to debug this I get the response of

ImportError: No module named code

If however I run it like

   python ${BASE}/code/runserver.py

prettyPrint();

I don't have any issue.
