[FIXED] Get Output From the logging Module in IPython Notebook

Issue

When I running the following inside IPython Notebook I don't see any output:

import logging
logging.basicConfig(level=logging.DEBUG)
logging.debug("test")

Anyone know how to make it so I can see the "test" message inside the notebook?

Solution

Try following:

import logging
logger = logging.getLogger()
logger.setLevel(logging.DEBUG)
logging.debug("test")

According to logging.basicConfig:

Does basic configuration for the logging system by creating a StreamHandler with a default Formatter and adding it to the root logger. The functions debug(), info(), warning(), error() and critical() will call basicConfig() automatically if no handlers are defined for the root logger.

This function does nothing if the root logger already has handlers configured for it.

It seems like ipython notebook call basicConfig (or set handler) somewhere.
