For me it looks like there are instabilities because undetected chromedriver maybe uses multiprocessing already, but isnt there any way where i can open multiple Browsers with UC and process each iteration parallel?
Edit: i debugged and the error appears after trying to execute this line:

I am trying to host django project on EC2 usnig apache2 which is using mongodb atlas as database.
When I am running this locally on EC2 after openning some port like 8000, it runs properly but on apache it's giving error.

I have a model defined in Django 3.1 like
class MyModel(models.Model):
def get_path(path):
def wrapper(instance, filename):
# code to make the path
return 'path/created/for/filename.jpg'
return wrapper
image = models.ImageField(upload_to=get_path('files/'))
but when I do
python3 manage.py makemigrations
I am getting a ValueError:

ValueError: Could not find function wrapper in myproject.models.
Normally python can have a function return a function, so what is the error here? If I create the model with a dummy path, do makemigrations, and then add the function it works fine in my code. It just seems to be erroring in makemigrations.
I have to start using odoo 12 on my job but I can't start using it, I have already 5 days searching on google to find an answer.
I would be very grateful if you could please help me, with some of your wisdom :)
After I install odoo on my computer and visit localhost:8069 for first time it asks me to create my database but after I do this it doesn't load the login page instead it gives me an 500 internal server error with this console log every time I refresh the page:

I have set up Airflow on an AWS EC2 server with Ubuntu 18.04, Python 3.6.9. The DB backend is a 5.7.26 MySQL, I am using a LocalExecutor. The setup is nothing more than:
apt-get install python3 python3-pip python3-venv libmysqlclient-dev
I install Airflow with pip3 install apache-airflow[mysql]==1.10.9, init DB connection, start the webserver and it works both normally and with -D. The scheduler, however, works only when run in the foreground. Trying to run it as a daemon fails with the following trace:

I am trying to set up a server for semi-production purposes, so this is actually a blocker for me. I would be grateful for any advice.
EDIT
I tried using mysql-connector-python==8.0.18 and the scheduler did run as a daemon, but an attempt to open a dag failed with the following trace:
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x80 in position 0: invalid start byte
The above exception was the direct cause of the following exception:

EDIT 2
What finally did work was using mysqlclient by specifying the SQLAlchemy connection string to begin with mysql+mysqldb. I am not giving this as an answer, because the initial problem persists.
I'm trying to make a program that uses python-telegram-bot, and I need to use Python 3 for that. But when I try to launch it using Python 3, I get some error I don't quite understand. The same happens when I use the built-in examples. Could somebody explain what it means? The precise output of the program follows.
