How to serialize python script across servers?

I started using Prefect recently and I noticed I can add decorators to some methods then submit them to prefect. It will then run my script remotely on an agent server. I'm wondering how it is possible to use an attribute and to serialize a method somehow for remote execution.

Example Prefect python script

import sys
import prefect
from prefect import flow, task, get_run_logger
from utilities import AN_IMPORTED_MESSAGE


@task
def log_task(name):
    logger = get_run_logger()
    logger.info("Hello %s!", name)
    logger.info("Prefect Version = %s ", prefect.__version__)
    logger.debug(AN_IMPORTED_MESSAGE)


@flow()
def log_flow(name: str):
    log_task(name)


if __name__ == "__main__":
    name = sys.argv[1]
    log_flow(name)
