Hello, having some trouble here.

I'm developing an app using the postgis backend in django, i'm releasing it using an apache server on Centos 7, i'm using mod_wsgi for python 3.6 and i've already published a test "hello world" app without trouble, however when i try to publish my app a 500 internal error, when i check the error log the next text appears:

mod_wsgi (pid=26812): Target WSGI script '/var/www/html/simulacros/simulacros/wsgi.py' cannot be loaded as Python module.

 MemoryError

I know "MemoryError" is self-explanatory however when i asked the system administrator if there was a memory problem he informed me there wasn't any. This leaves me wondering where can i be wrong.

In case someone asks here's my wsgi.conf file:

Alias /static /var/www/html/simulacros/static

<Directory /var/www/html/simulacros/static>
