@Marvin how to replace prefect logger to loguru

Before diving into replacing the Prefect logger with Loguru, it's important to know which version of Prefect you are using, as the method might vary slightly between versions. Let me find some relevant information about replacing or integrating the Prefect logger with Loguru for both Prefect 2.x and 3.x. This way, you'll have guidance regardless of your Prefect version. Please hold on for a moment! It seems there was a little hiccup in searching for the specific methods of replacing the Prefect logger with Loguru due to some technical issues. But no worries, I can still guide you through a general approach! To replace the Prefect logger with Loguru, here's a general method you can follow: 1. Install Loguru: If you haven't already installed Loguru, you can do so with pip:

pip install loguru

2. Set Up Loguru Logging: You need to configure Loguru before your Prefect flow runs. You can do this by defining a logging configuration that utilizes Loguru. 3. Redirect Prefect Logs: Prefect typically uses Python's standard logging library. To redirect Prefect logs to Loguru, you need to intercept logs from the

logging.Logger

and redirect them to Loguru's logger. Here's an example snippet to help guide you:

python
from loguru import logger
import logging

class InterceptHandler(logging.Handler):
    def emit(self, record):
        # Get corresponding Loguru level if it exists
        try:
            level = logger.level(record.levelname).name
        except ValueError:
            level = record.levelno

        # Find the caller from where originated the logging call
        frame, depth = logging.currentframe(), 2
        while frame.f_code.co_filename == logging.__file__:
            frame = frame.f_back
            depth += 1

        logger.opt(depth=depth, exception=record.exc_info).log(level, record.getMessage())

# Replace default handler
logging.basicConfig(handlers=[InterceptHandler()], level=0)

# Now you can use Loguru's logger as usual
<http://logger.info|logger.info>("This message will be logged by Loguru.")

4. Run the Prefect Flow: With this setup, any log produced via Prefect's logging system should be redirected to Loguru. This is a general strategy that often works, but the exact configuration might depend on the specifics of your project or the Prefect version you're using. If you have access to additional resources or documentation for your Prefect version, I'd recommend checking there for any version-specific settings. And remember, if all else fails, a good addition of humor like Marvin's dry wit might make log debugging a little more bearable!
