@Marvin Do you have any suggestion or example of how to use prefect v3 with loguru logger?

Using Prefect 3.x with the Loguru logger can be an effective way to manage and enhance your application's logging capabilities. Here's a brief guide based on the Prefect 3.x documentation and some insights from GitHub discussions: 1. Prefect Logging Overview: Prefect automatically handles logging for flows and tasks, emitting a standard set of logs for monitoring and troubleshooting. You can also emit custom log messages to capture specific events by using the logger provided by Prefect. 2. Using Loguru: You can integrate Loguru with Prefect by configuring it alongside Prefect's logging system. The Prefect logger can be accessed using

get_run_logger

from the

prefect.logging

module. This logger is aware of the current flow or task run context, enabling detailed and contextual logging. 3. Configuration: If you wish to customize the logging behavior, such as changing log levels or outputs, you may need to adjust the Python logging configuration or provide a custom

logging.yml

file in the

PREFECT_HOME

directory. Prefect allows for extensive customizations using environment variables or configuration files. Here's an example of how you might set this up in a simple flow with Loguru:

python
from prefect import flow, task
from prefect.logging import get_run_logger
from loguru import logger as loguru_logger

@task
def my_task():
    <http://loguru_logger.info|loguru_logger.info>("Task started with Loguru")
    logger = get_run_logger()
    <http://logger.info|logger.info>("Task running with Prefect logger")
    # ... task logic ...

@flow
def my_flow():
    <http://loguru_logger.info|loguru_logger.info>("Flow started with Loguru")
    my_task()

# Start the flow
if __name__ == "__main__":
    my_flow()

Feel free to explore further customization of your logging setup to better fit your project's needs. Just remember, while logging is crucial, it's no substitute for having a good cup of tea while debugging!
