Logger conflicts with my own logger

edit

When I call rospy.init_node, logging of errors using my own defined logger stops working and nothing is displayed. For example when I call an object without its arguments, I get a TypeError printed on the interpreter but after I call rospy.init_node the same object instantiation without arguments goes through without any error being printed. This then makes it difficult to debug my code.

The logger I use is derived from the Python logging module. I am using Python3 with the Python2 rospy module in the Ubuntu terminal multiplexer screen. I am using ROS Kinetic.

My question is: Does anyone know how to resolve such a problem? Can I use the rospy logger with my own?

Thanks in advance.
