Python – No handlers could be found for logger “OpenGL.error”

loggingopenglpyopenglpythonwxpython

Okay, what is it, and why does it occur on Win2003 server, but not on WinXP.

It doesn't seem to affect my application at all, but I get this error message when I close the application. And it's annoying (as errors messages should be).

I am using pyOpenGl and wxPython to do the graphics stuff. Unfortunately, I'm a C# programmer that has taken over this Python app, and I had to learn Python to do it.

I can supply code and version numbers etc, but I'm still learning the technical stuff, so any help would be appreciated.

Python 2.5, wxPython and pyOpenGL

Best Solution

Looks like OpenGL is trying to report some error on Win2003, however you've not configured your system where to output logging info.

You can add the following to the beginning of your program and you'll see details of the error in stderr.

import logging
logging.basicConfig()

Checkout documentation on logging module to get more config info, conceptually it's similar to log4J.
