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 customise project logging in conf/<env>/logging.yml using standard Kedro mechanisms for handling configuration. The configuration should comply with the guidelines from the logging library. Find more about it in the documentation for logging module.

Use logging

After reading and applying project logging configuration, 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")


The name of a logger corresponds to a key in the loggers section in logging.yml (e.g. kedro.io). See Python’s logging documentation for more information.

Logging for anyconfig

By default, anyconfig library that is used by kedro to read configuration files emits a log message with INFO level on every read. To reduce the amount of logs being sent for CLI calls, default project logging configuration in conf/base/logging.yml sets the level for anyconfig logger to WARNING.

If you would like INFO level messages to propagate, you can update anyconfig logger level in conf/base/logging.yml as follows:

        level: INFO  # change
        handlers: [console, info_file_handler, error_file_handler]
        propagate: no
