This looks like a numpy bug. It seems that float32_arrtype's name is incomplete. Its tp_name field should start with a module name, but since it doesn't, Python assumes that it is a builtin type: >>> import numpy >>> numpy.float32.__module__ '__builtin__' You should report this bug either to the numpy list: https://lists.sourceforge.net/lists/listinfo/numpy-discussion or to their bug tracker: http://projects.scipy.org/scipy/numpy Ziga -- http://mail.python.org/mailman/listinfo/python-list
