My WSGI application cannot be loaded as Python module. What am I doing wrong

Question

I have been trying to get a WebAPI to run on the server. However I keep getting this error everytime I log into the site via the web browser

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, jordi.duch@gmail.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log. Apache/2.2.22 (Ubuntu) Server at complex.ffn.ub.es Port 80

I check the error log file and I have the following.

[Thu Jul 14 17:16:08 2016] [error] [client 161.116.80.82] mod_wsgi (pid=21450): Target WSGI script '/home/xarxes_ub/python_code/configure.wsgi' cannot be loaded as Python module.

I configured my .wsgi file based on the directions given on this site http://flask.pocoo.org/docs/0.11/deploying/mod_wsgi/

It mentions specifically "Keep in mind that you will have to actually install your application into the virtualenv as well. Alternatively there is the option to just patch the path in the .wsgi file before the import: import sys sys.path.insert(0, '/path/to/the/application')" Which is what I did

Here is the configure.wsgi file

import sys
sys.path.insert(0, '/home/xarxes_ub/python_code/MenuUB2.py')

from MenuUB2 import app as application

In addition here is my apache configuration file that I edited. I highlighted the lines I added with ###.

Please tell me what needs to be done. If I can get this to work I'd be so relieved. Also note that I tried changing the "configure.wsgi" file to return a static and it works Example is here

def application(environ, start_response):
    status = '200 OK'
    output = 'Hello World!'

    response_headers = [('Content-type', 'text/plain'),
                        ('Content-Length', str(len(output)))]

   start_response(status, response_headers)

    return [output]

Alright turns out I had a mistake in my configure.wsgi file

I should name the folder that has the application and not the absolute path to the application so /home/xarxes_ub/python_code not /home/xarxes_ub/python_code/MenuUB2.py

Here is the edited configure.wsgi file

import sys
sys.path.insert(0, '/home/xarxes_ub/python_code')

from MenuUB2 import app as application
