Also, when I try to run a program where I imported selenium or any other installed module from pip it gives me the same error.
This is my pip version: pip 20.0.2 from /usr/lib/python3.8/site-packages/pip (python 3.8)
Thank you all in advance!

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 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:

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.

Note that before installing Anaconda 3, I uninstalled Anaconda 2 (with Python 2.7).
How can I fix this?
Finally I found a solution in the web :
I had to execute the following command :
python -m ipykernel install --user
