how to set WSGI of appache2 to work with python 3.7?

Question

I am using ubuntu 16.04 and installed python 3.7 and set it to default using this instructions: Unable to set default python version to python3 in ubuntu when I type python in the console I get python3.7 , i tried to set appache2 to work with python 3.7 using :

sudo add-apt-repository --yes ppa:deadsnakes/ppa
sudo apt-get update --yes
sudo apt-get install --yes python3.7
sudo apt-get install --yes python3-pip
sudo apt-get --yes install python3-pip apache2 libapache2-mod-wsgi-py3 
sudo a2enmod wsgi
sudo apt install --yes python-django-common
sudo apt-get  install --yes python-django

but still I get exceptions of import packages that are already installed in /var/log/apache2/error.log when try to reach out to the server that I don't get at the terminal like this :

Traceback (most recent call last):
 File "/home/ubuntu/my_code/wsgi.py", line 11, in <module>
     from django.core.wsgi import get_wsgi_application
 ImportError: No module named 'django'
 mod_wsgi (pid=75005): Target WSGI script '/home/ubuntu/my_code/wsgi.py' cannot be loaded as Python module.
mod_wsgi (pid=75005): Exception occurred processing WSGI script '/home/ubuntu/my_code/wsgi.py'.
 Traceback (most recent call last):
  File "/home/ubuntu/my_code/wsgi.py", line 11, in <module>
  from django.core.wsgi import get_wsgi_application

and

mod_wsgi (pid=75005): Target WSGI script '/home/ubuntu/my_code/wsgi.py' cannot be loaded as Python module.

even though i have django installed in python 3.7 another error i get is after service restart :

 mod_wsgi (pid=89300): Call to 'site.addsitedir()' failed for '(null)', stopping.

my wsgiy.py :

import os
import sys

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "servicesite.settings")
path='/home/ubuntu/my_code/'

if path not in sys.path:
  sys.path.append(path)

os.environ['DJANGO_SETTINGS_MODULE'] = 'my_code.settings'
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

What can be the reason for this error?

you need to built python and then built wsgi since the default wsgi is built based on the is system python use this tutorial https://medium.com/@garethbjohnson/serve-python-3-7-with-mod-wsgi-on-ubuntu-16-d9c7ab79e03a
