Hi Ilia, That's a warning from the standard Python library "logging". I guess that PyOpenGL (I presume you're using version 3) is sending a message to be logged, but there is not logging handler installed for it. To use the logging module's default logging settings, call the following at the start of your program: import logging logging.basicConfig() Otherwise, you could disable the warning and any logging output by using the following, but you may miss some relevant information that way: import logging logger = logging.getLogger('OpenGL') logger.setLevel( logging.CRITICAL ) ilia ivanov wrote: > Hello guys, > > Whenever I`m trying to run the .py demos or import from VisionEgg.Core I > got a nasty error message "No handler could be found for logger > "OpenGL.ctypes"... > Im running Windows XP, Python 2.5.4, and all the packages that are > required for visionegg are installed. > Any suggestions? > Thanks. > > -- Dr. Andrew D.
