Logging

Note: This documentation is based on Kedro 0.14.0, if you spot anything that is incorrect then please create an issue or pull request.

Kedro uses, and facilitates the use of Python’s logging library, by providing a default logging configuration. This can be found in conf/base/logging.yml in every project generated using Kedro’s CLI kedro new command.

Configure logging

You can configure the logging by simply adding the following lines at the entry point of your application (e.g., src/<package_name>/run.py):

from logging.config import dictConfig
from kedro.config import ConfigLoader

conf_paths = ['conf/base', 'conf/local']
conf_loader = ConfigLoader(conf_paths)
conf_logging = conf_loader.get('logging*', 'logging*/**')
dictConfig(conf_logging)

The configuration should comply with the guidelines from the logging library. Find more about it here.

Use logging

After configuring the logging using the example above, kedro will start emitting the logs automatically. To log your own code, you are advised to do the following:

import logging
log = logging.getLogger(__name__)
log.warning('Issue warning')
log.info('Send information')
