creating session via Boto3 is giving error - ModuleNotFoundError: No module named 'multiprocessing.managers'; 'multiprocessing' is not a package

Question

I am trying to create a simple s3 session in Pycharm and it is not letting me create for the love of God. I have checked multiple times still the same error, can anyone please nudge me in the right direction?

My code -

from secrets import AWS_SECRET_ACCESS_KEY, AWS_ACCESS_KEY_ID, AWS_SESSION_TOKEN
import boto3
import multiprocess as mp
import multiprocessing

session = boto3.session.Session()

session = boto3.session.Session(aws_access_key_id=AWS_ACCESS_KEY_ID,
                                aws_secret_access_key=AWS_SECRET_ACCESS_KEY,
                                aws_session_token=AWS_SESSION_TOKEN)

s32 = boto3.resource('s3')

Please refer to the AWS SDK Github where code examples are located. Your code looks different from the Python examples. See this example.
