Apache2 can not load wsgi.py - django

Question

I am using an Ubuntu 14.10 X86_64 system with softwares in below:
python 3.4
apache2
libapache2-mod-wsgi-py3
django1.8
I created a project by django1.8 at this path:
/var/www/html/koorimeo
I've noticed that django-admin startproject will generate a wsgi.py file by default and I haven't change its content.
I configured apache2 under the official document(How to use Django with Apache and mod_wsgi) details:
I modified 000-default.conf for I don't want to setup another Virtual Host. and This is What I added:
#000-default.conf
<VirtualHost *:80>
...
<Directory /var/www/html/koorimeo/koorimeo>
<Files wsgi.py>
Require all granted
</Files>
</Directory>
...
</VirtualHost>
After that I declare WSGIAlias and WSGIPythonPath in apache2.conf:
#apache2.conf
#I want to leave "/" for other use...
WSGIScriptAlias /koorimeo /var/www/html/koorimeo/koorimeo/wsgi.py
WSGIPythonPath /var/www/html/koorimeo/koorimeo
After finished setting files I restarted apache2 service and login into 127.0.0.1/koorimeo, it returned a 500 error message...
I looked up the error log file and get these error message:
bing#k-lab:/var/log/apache2$ tail error.log

According these message I found that apache2 can not find this module:
/var/www/html/koorimeo/wsgi.py
So I copy this path and try to get me clear wheather this file do exist:
bing#k-lab:/var/log/apache2$ ls /var/www/html/koorimeo/koorimeo/wsgi.py -l
and the system returned this message which told me that the file is truly exists...
-rw-rw-r-- 1 bing bing 389 4月 25 14:21 /var/www/html/koorimeo/koorimeo/wsgi.py
And I also make sure that I've installed libapache2-mod-wsgi-py3, I did find wsgi.so in proper location.
I've found wsgi.load in modes-enable and pointed the wsgi.so in right place:
LoadModule wsgi_module /usr/lib/apache2/modules/mod_wsgi.so
So... I am confused...
Please tell me why can't apache2 find this wsgi.py file?

Remove mod_python from Apache if you are not using it.
Your mod_wsgi module was compiled for Python 3.4.0, but mod_python was compiled for 2.7.6. Because mod_python is using a different version it is overriding what Python version is used and this will stop mod_wsgi from working.
Read the many sections in the documentation starting at:
http://code.google.com/p/modwsgi/wiki/InstallationIssues#Using_ModPython_and_ModWsgi
