Azure / Django / Celery / Ubuntu | tkinter & libtk8.6.so import issue

UPDATE / SOLUTION
Per Sytech's answer....
Did not realize that the build was in Ubuntu which has all the packages but when Azure deploys it to a Linux container, the needed packages were missing.
Like in other questions/answers just add these installs to a startup script that Azure will use
ex.
#!/bin/bash
apt-get update
apt-get install tk --yes
python manage.py wait_for_db
python manage.py migrate
gunicorn --bind=0.0.0.0 --timeout 600 app.wsgi --access-logfile '-' --error-logfile '-' &
celery -A app worker -l info --uid=1
Original Post:
When Azure builds & deploys a Python3.9 Django/Django-Rest WebApp it has been failing in it's start up.

I have come across other answers to this needing to make sure that tkinter is installed with sudo apt-get python3-tk which I have added to the deployment yml file
Though it still seems to have issue. Reverting back to previous code for deployment is successful and the only feature that has been added to the application is Celery. Not sure if that has anything to do with it or not.
Am I adding the installation of the tk/tkinter in the wrong sequence?
When I revert the to previous code and have a successful build/deploy I ssh into the container and run the python shell and try to manually import the tkinter module.
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "/opt/python/3.9.7/lib/python3.9/tkinter/__init__.py", line 37, in <module>
import _tkinter # If this fails your Python may not be configured for Tk
ImportError: libtk8.6.so: cannot open shared object file: No such file or directory
it errors out like expected.
when I run apt-get update && apt-get install python3-tk --yes manually in the container, then go back to the shell on the container there is not error importing tkinter.
Which leads me to believe something is not installing in the right place? virtualenv? Or is being overwritten in the build process?

If this error is occurring after deployment, you need to install tkinter in your deployment environment, which is separate from GitHub Actions runs.
On your server is running Ubuntu 20 and, make sure the tk package is installed, which provides the libtk8.6.so file needed.

I came across this error because a simple mistake.
The IDE add from turtle import up to my .py and I didn't notice

import sqlparse ModuleNotFoundError: No module named 'sqlparse'

I have installed
pip install sqlparse
pip3 install sqlparse
conda install sqlparse
But still getting sqlparse module error
Why is that?

I am getting the following error.
I am not sure where should I install sqlparse

Since you also tried conda install, I am supsecting that you have anaconda or miniconda installed. pip and pip3 probably point to the python version managed by conda. However, your error message suggests that your script is being executed with a python version that is located at
C:\Users\zesha\AppData\Roaming\Python\Python39\
To install for that version of python specifically, you could try something like (might need to check that that is actual path to python.exe in that folder):
C:\Users\zesha\AppData\Roaming\Python\Python39\python.exe -m pip install sqlparse
Alternatively, run your script with the python that is managed by conda

Spyder not launching from one of the Anaconda environments

I'm new to this. I have begun learning OpenCV with Python and following the course directions I've successfully created an Anaconda environment from which I can easily import CV2 and carry out my course. So far, I have experienced no problems in working with this environment.
Now, I would like to begin using Spyder which launches well from the default/base environment but does not launch from the "opencv-course" environment which I created. By contrast, Jupyter Labs and Notebooks launch well on either environment.
I've attempted to uninstall/reinstall Spyder using Administrator privileges when launching Anaconda, but to no avail.
Could anyone forward a suggestion?
Many thanks!

After checking out this answer here:
Spyder failed to launch in Anaconda after update (4.1.2)
I've solved the problem by downgrading the version of Pylint from 2.5 to 2.4.4. It now works fine.
Many thanks!

Cannot access python shell from virtualenv and Django

I'm on Windows 10.
I tried to install channels to use websockets with Django but it doesn't work. I got the following error :
Failed building wheel for Twisted
I have still not succeeded to install channels.
But now I have a new problem, I can no anymore access Python shell from my virtual environment that I use for Django.

I have no idea to solve my problem ... Someone could bring me help ?

Try install channels by using pip install channels
then run shell again

Seems like you broke something when you tried to install channels. From the spares information I guess that easiest course of action is to simply use a new virtual environment. After all that is the point of a virtual environment, if it breaks you can just rebuild it.
Manually fixing the virtual environment usually (this is my personal experience) takes more time then just setting up a new one.
For your installation trouble we need more info and you should open a new question.
So just deactivate your current environment (this might help), delete it and set up a new one.
Keep in mind that this will only bring the shell back and give you a "fresh start". Your installation problem will usually not disappear!

It seems to be incompatibility of Python 3.7 and your current version of Django. You can find more details in similar question
What I can suggest is to upgrade your Django 2 or use Python 3.6.
Here you can see that Python 3.7 is compatible with Django 1.11.17 version.

Can we see the code u a=have written in manage.py
Who ever tries python for the first tym they does a very basic mistake of inidnantion. Though it ll be inditnation error for sometime it will throw some other prioritized error. !CHECK FOR INDINANATION

Thanks guys for the help.
After a lot of headbang, I came to know that there were a lot of modules missing from req.txt file which were required to build the project. They were mentioned in some other file.
After installing all the required modules, and running the migrations, I was able to run the project.
