Get Output From the logging Module in IPython Notebook

Question

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

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


        

Answer 1

Bear in mind that stderr is the default stream for the logging module, so in IPython and Jupyter notebooks you might not see anything unless you configure the stream to stdout:

import logging
import sys

logging.basicConfig(format='%(asctime)s | %(levelname)s : %(message)s',
                     level=logging.INFO, stream=sys.stdout)

logging.info('Hello world!')
