To create a weak reference to an object, you use the weakref.ref function. Got it working when I replaced Python 2.7 with Python 2.6.4 as suggested.Is there a way to keep different version of Python? The Houdini system requirements still read as though Python 2.6.4 is the latest supported version.Maybe Houdini can't find the new Python library and executable paths. Can you please give me more of an idea about what I am looking for?
