This question has been asked before here but the solution does not work for me. My python venv configuration is not playing well with the apache2 mod_wsgi and I cannot root-cause the issue. At present, I cannot comment on this question so I'm posting another one
Here are the apache2 error logs when trying to log into the site.

I referenced these instructions from DigitalOcean trying to install pgAdmin4 on Ubuntu 16.04.
Edit: I used a python3 venv instead of anaconda virtual env and everything worked fine. So the root cause is the anaconda system. There's a discussion on the mod_wsgi mailing list about this

I have been trying to get my django app deployed for a while now and no matter what I have followed and tried I keep running into errors.
I am currently getting this error:
Target WSGI script '/home/brickmane/djangoapp/myserver/backend/core/wsgi.py' cannot be loaded as Python module.
and
ModuleNotFoundError: No module named 'contextvars'
which is not something I used myself in my project.
I have tried some solutions like using:
sudo chmod a+x wsgi.py
and trying libapache2-mod-wsgi-py3 vs libapache2-mod-wsgi
my apache2.conf file where I placed my virtual host and the settings for my app:

WSGIDaemonProcess backend python-path=/home/brickmane/djangoapp/myserver/backend/core python-home=/home/brickmane/djangoapp/myserver/venv

my wsgi.py file:

# add the hellodjango project path into the sys.path
sys.path.append('/home/brickmane/djangoapp/myserver/backend/')
sys.path.append('/home/brickmane/djangoapp/myserver/backend/core/')
# add the virtualenv site-packages path to the sys.path
sys.path.append('/home/brickmane/djangoapp/myserver/venv/lib/python3.10/site-packages')
# poiting to the project settings
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "core.settings")
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

You have configured Apache with python3.6 but run python3.10 in your virt.env (contextvars is part of python since version 3.7)
You should always run Apache with the same python version as in the virt.env
I a trying to run a "hello world" python application from the server using Apache web server port 80. Here, I have setup python virtual environment compacting with python version 3.8. created virtual host, wsgi file and now trying to call the URL on browser, I am getting 500 internal server error. Apache error log file details provided here.
1. Ubuntu 18.04,
2. Python 3.8,
3. Apache 2.4

I have installed flask on the virtual environment and trying to activate from the WSGI file execution. However, this is not working for me.
FYI : The commented lines on virtual host is already I have tried.
its been a nightmare trying to deploy django using apache and wsgi on ubuntu server 18, I created a virtual environment, installed dependencies, restarted apache many times however apache wsgi cant find django in my virtual environment.
I can run manage.py runserver so virtual environment dependencies are ok.
My python version for venv is 3.8
this is apache error log:

I'm trying to deploy this application in a debian 9 server. I've tested it on my kali box and it worked fine just by installing flask and paramiko and configuring apache.
I've tried rinstalling some packages like paramiko, flask and Werkzeug but with no success.
I even created a new app with a simple hello world message. It works fine until i import paramiko and then i get the "permission denined" error.
My test app contains three files.
my_flask_app.py
from flask import Flask
import paramiko
app = Flask(__name__)
#app.route("/")
def hello():
return "Hello world!"
if __name__ == "__main__":
app.run()
my_flask_app.wsgi
import logging
import sys
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0, '/var/www/html/ExampleFlask/ExampleFlask/')

The apache user didn't have the needed permission to read from that directory. We only to add the read permission for the other group with the following command :

Usually, this error means there is an error in the Django project somewhere. It could be hard to locate.
You can try multiple solutions like:
1. Restart Apache
2. Execute makemigrations and migrate Django commands
3. Modify your wsgi.py file so you can manage the exception
A little note, in the line File "/home/abhadran/myenv/lib/python3.6/site-packages/django/apps/registry.py" indicate that you're using Python 3.6 and not Python 3.5 as you mentioned in your description.
Python 3.6 is officially supported until Django 1.11, so you maybe must upgrade your Django version or downgrade your Python in your venv.
