Is there any way to change a rospy node's log level while it is running? says that you must pass in a parameter to rospy.init_node(), which means you need to kill and restart the node...

Also, I am curious why rxloggerlevel doesn't work for python nodes.

Not much hacking is required to accomplish this:

import rospy
import logging

def set_rospy_log_lvl(log_level):
    logger = logging.getLogger('rosout')

You can use this function wherever you want (after rospy.init()) to change the log level. Works in Melodic.

Example usage:

rospy.init("my_node", anonymous=True)

You currently can't do this in rospy without some severe internal API hacking. This would make a good feature request ticket (or patch).

rxloggerlevel works against an API that was developed solely for roscpp. I've been meaning to add it to rospy, but the API needs some cleanup and it's been lower priority.

You can also use rosrun rqt_logger_level rqt_logger_level
