The global namespace in Python is actually a module-wide namespace. You have to put an import numpy at the top of every module that uses numpy. I lack the fantasy to imagine what exactly you have done that "global numpy" has the described effect. It's probably not pretty. Peter -- http://mail.python.org/mailman/listinfo/python-list
