Ubuntu 16.04 Server error about wsgi module in wsgi.py

Question

I'm gonna set a django app on a ubuntu server in a virtual host.
I have configured my virtual host so that something comes up!
But it persists on giving me 500 internal error because of some issues as you see here:

mod_wsgi (pid=31972): Target WSGI script '/var/www/mmcba/mmemp/wsgi.py' cannot be loaded as Python module.
mod_wsgi (pid=31972): Exception occurred processing WSGI script '/var/www/mmcba/mmemp/wsgi.py'.

I really appreciate your responses

Update #2

if I use this code in my wsgi.py:

import os

from django.core.wsgi import get_wsgi_application

os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp.settings'
application = get_wsgi_application()

stack trace will become this:(mmemp is my app's name):

 mod_wsgi (pid=5579): Target WSGI script '/var/www/mmcba/mmemp/wsgi.py' cannot be loaded as Python module.

     mod = importlib.import_module(self.SETTINGS_MODULE)
   File "/usr/lib/python2.7/importlib/__init__.py", line 37, in import_module
     __import__(name)

My Virtual Host Config., Here it is:

Listen 80

NameVirtualHost 148.251.218.202:80

<VirtualHost *:80>
        ServerAdmin webmaster@mmcba.com
        ServerName mmcba.com
        ServerAlias www.mmcba.com

        WSGIScriptAlias / /var/www/mmcba/mmemp/wsgi.py

        <Directory /var/www/mmcba/mmemp>
        <Files wsgi.py>
        Require all granted
        </Files>
        </Directory>

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

</VirtualHost>

Show the mod_wsgi configuration you are using. It doesn't look like you have told mod_wsgi where you project is located. — Graham Dumpleton, Aug 13 '17 at 20:44
I've added my virtual host configuration and also updated my stack trace --after reversing some mistakes. it's nearly a new error. Would you please take a look at the second stack trace again. & thank you for your response — Arshamnm, Aug 13 '17 at 21:26
You should use daemon mode of mod_wsgi, not embedded mode. You then aren't telling mod_wsgi where your project code is located as per the Django documentation. See http://modwsgi.readthedocs.io/en/develop/user-guides/virtual-environments.html and https://docs.djangoproject.com/en/1.11/howto/deployment/wsgi/modwsgi/ — Graham Dumpleton, Aug 13 '17 at 22:33
Update the configuration in your question to show what you are using now. — Graham Dumpleton, Aug 14 '17 at 10:15
Got it. I added project and app dirs to sys.path and finally it found settings module. Thank you — Arshamnm, Aug 14 '17 at 10:23

If you're using django 1.7+ do replace contents of your wsgi.py with this:

import os

from django.core.wsgi import get_wsgi_application

os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp.settings'
application = get_wsgi_application()

OR try adding the following lines to settings.py

import django
django.setup()

There is a similar question here. Hope it helps.

Thank you but it's not working I've inserted new stack trace at the bottom of my question – Arshamnm Aug 13 '17 at 13:23
Is the project working in your local machine? Also please check whether there is `__init__.py` file inside your app directory (mmemp) – akhilsp Aug 13 '17 at 18:12
Of course, it's working like a charm! yeah there is one :( – Arshamnm Aug 13 '17 at 20:06
You should not place wsgi.py in your app folder, instead put it in project folder. – akhilsp Aug 14 '17 at 08:17

Solution:
Add project and App dir to sys.path in wsgi.py and it'll work.
It works for every unknown module in your app

import sys
sys.path.append('<Project_Directory>')
sys.path.append('<Project_Directory>/AppName')
