Please make sure that django is in PYTHONPATH.
To test import django from a python shell
Python 3.6.1 (default, Dec 2015, 13:05:11)
[GCC 4.8.2] on linux
>>>import django

You need to setup mod_wsgi which has been compiled against python 3 version you use.
Please refer here to verify what version of python your mod_wsgi is compiled for-> http://modwsgi.readthedocs.io/en/develop/user-guides/checking-your-installation.html

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:

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'm experimenting and working on a Flask webpage what's gonna use some data from MySQL database and after a little coding I got internal server error and I don't know why.
After several days I cant work out the problem what can I do for it to work?
I'm using Python3, the server where is hosted is Ubuntu system and I can reach the site via LAN right now with the servers LAN domain (server's name) name that I host via Hyper-V cause I don't have a spare PC for that with Ubuntu on it.
The weird part abut it that when I test it locally on my laptop I wont get the 500 Error only if I want to connect the page what's hosted on the server virtual machine.
Because I don't know where is the problem I uploaded most of the files to GitHub, this gonna be changed of course and later deleted for security reasons but now its easier.

Do not download the module I mistook content_management as pip module. you can uninstall the module pip uninstall contentful_management
The error comes because you are importing module in init.py.
try this:
from name_of_the_parent_directory import content_management
You an try using
from . import content_management
name_of_the_parent_directory - means the parent directory, in your github it will be webpage.

Please help me to resolve the issue. It would be very helpful for me.
Are you sure that azure.storage is installed on the machine?
Please install it before you run your project:
script: pip install azure-storage
Try pip list to see what all modules are installed on your machine.
Also, see that, the version which is used by your code, is installed on your machine.
I deploy flask with apache on CentOS7
And I want Oracle database to insert or select when user access.

And run flask on virtual env.
flask run

I followed this article for deploy flask with apache.
https://dev.to/sm0ke/flask-deploy-with-apache-on-centos-minimal-setup-2kb7
and install cx_Oracle and I copied it where I thought I needed it.
Here my tree
/etc/httpd/modules/
|-cx_Oracle.cpython-36m-x86_64-linux-gnu.so
|-cx_Oracle-8.0.1.dist-info
/var/www/hitme/lib/python3.6/site-packages
|-cx_Oracle.cpython-36m-x86_64-linux-gnu.so
|-cx_Oracle-8.0.1.dist-info
/usr/local/lib/python3.6/site-packages
|-cx_Oracle.cpython-36m-x86_64-linux-gnu.so
|-cx_Oracle-8.0.1.dist-info
But it still gives the error.
Is there any other way?
Ensure that the required Oracle Instant Client is installed to the Apache user by downloading
https://download.oracle.com/otn_software/linux/instantclient/199000/instantclient-basic-linux.x64-19.9.0.0.0dbru.zip
and unzip ut to a folder Apache user owns or is accessible for read and execute - lets say
/apache/oracle
After that, ensure PATH, ORACLE_HOME and LD_LIBRARY_PATH ist set properly as Apache User - i.e.
export ORACLE_HOME=/apache/oracle
export PATH=$PATH:$ORACLE_HOME
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME
If you start Apache as service then you may need to set the variables to root or user who starts apache.
I have a flask application running on apache server in the Linux box(ec2 instance), which calls the python script that does the work of moving the files from s3 to snowflake. The script works fine if executed directly. It throws the below error for the snowflake's ingest python module when trying to host it on apache using virtualhost and mod_wsgi. The module is installed in the default site packages.
Apache server version: 2.4.41
Python Version: 3.7
snowflake: snowflake_connector_python-2.1.3-py3.7-nspkg.pth
OS: AMAZON linux 2
Below is the apache error log, when i try to restart:

It looks like when you're executing this from mod_wsgi, you're using Python 2 instead of Python 3. The error message you see is happening because Snowflake's simple ingest manager uses type hints (via the typing module), which are not available in Python 2.
Here's a simple fragment that fails with the same error in Python 2 but succeeds in Python 3:
from typing import Text
def foo(bar: Text):
print(bar)
foo('huh')
