ImportError: cannot import name 'url' from 'django.conf.urls' in packages

I have a project of migrating django web app from Django-3.2.14 to Django-4.0. Immediately after migration, when I run the server I get the error as shown in Console output. When I traced the changes, it traced to django-compat package, which was being called by django-background-tasks package. my_env is my virutal environment.
We have latest version of django-compat, which is 1.0.15 and django-background-tasks, which is 1.2.5.
Could you please look into this?
Thank you in advance.

Updated answer
Sadly there is currently no supported version of django-background-tasks. It seems like you will not be able to upgrade to django 4.0 without migrate to any other package, which will do the same job as django-background-tasks.
https://django-background-tasks.readthedocs.io/en/latest/#supported-versions-and-compatibility
Old Answer
The package background_task is using the django-compat, which is not supported with new django versions.
D:\New_Folder\github\myenv\lib\site-packages\background_task\models.py
from compat import StringIO
As far as I can see in the stacktrace, there is no need to use the django-compat package anymore. The background_task package should use StringIO directly from the default io package.
You will need an updated version of the background_task package, which is not using the django-compat package anymore. As far as I can see there is no new version whithout the dependency.
https://django-background-tasks.readthedocs.io/en/latest/
https://github.com/arteria/django-compat
https://docs.python.org/3/library/io.html#io.StringIO

Django has removed the URL from version 4.0. Check the documentation here:
https://django-background-tasks.readthedocs.io/en/latest/#supported-versions-and-compatibility
Alternatively, you can degrade it back to 3.2.10, which removes the problem

Django runserver error: _frozen_importlib._DeadlockError: deadlock detected by _ModuleLock('django.test.signals') at 139824587568800

After adding 'rest_framework.authtoken' to INSTALLED_APPS (settings.py) and running python manage.py migrate I started to get a strange error when trying to run django server (the strange thing is, that the error appears on every 2nd or 3rd attempt, sometimes the server starts running without the error):

I am using: django 2.2.7 and django rest_framework 3.10.3. Thanks for any help.

There's a ticket on Django's issue tracker discussing similar issue: https://code.djangoproject.com/ticket/30352.
For a temporary fix, you can remove all .pyc files on your project and run the runserver command again.
find <path-to-your-project> -type f -name '*.pyc' -delete
NB: I use pyenv which stores the project's virtual environment in a different directory outside the project directory. Removing only the project's .pyc files work for me, but you may also try removing the virtual environment's .pyc files if needed.
For anyone who still gets this error, please kindly comment in the issue page to help Django developers reproduce and fix the error.

Django Crispy Forms

I am fairly new to Django and I have installed and am trying to use crispy forms in my web app.I have added crispy_forms to my installed apps with a comma after it. When I run the server I get this error:

I don't know what is wrong with my code. I have found some other users who have issues using crispy forms but are getting a different error. They were also unable to import crispy forms from the python shell but that is working for me. Even if I only add crispy forms to my installed apps without trying to apply it in my templates, I still get an error. Please let me know what I'm doing wrong. Thanks in advance.

Your version of django-crispy-forms is outdated, this has been fixed.
Update it by running:
pip install django-crispy-forms -U
-U makes pip upgrade your current installation to the newest.
You can find more about it by running pip install -h

The problem has been solved. I uninstalled the django version I had and used:
pip install Django==2.1.7
Thank you #YugandharChaudhari for helping me realize to change versions.

sqlite and pyvenv and django

I am new to both python and django. I am trying to get python 3.4 and django 1.6.4 working within a pyvenv-3.4 environment on Linux Mint Mate 13. I followed the procedures of Using a virtual environment with Python 3.4 for "Building Python 3.4 from source" and "Using pyvenv-3.4". Then following the Django tutorial at Writing your first Django app, I was able to create "mysite" with startproject. But the command "python manage.py runserver" failed with
django.core.exceptions.
ImproperlyConfigured: Error loading either pysqlite2 or sqlite3 modules
(tried in that order):
No module named '_sqlite3'
Sorry, I do not recall why I resorted to compiling from source, but it may be that I was unable to find pyvenv in the standard Ubuntu downloads using apt-get. In any case, the Makefile for the source distribution does not have an "uninstall" target, so it seems I am stuck with whatever make installed, and without a plan for what to do next to actually get pyvenv-python-django working.
I am updating this post by attaching the full error:

It sounds like you didn't have the SQLite development libraries installed at the time you built CPython from source. The build process conditionally includes some features based the availability of underlying development libraries.
On Debian GNU/Linux and derivatives, install libsqlite3-dev. Then re-run ./configure, make and make install.
