Hi All, Do PyObject arrays works, more specifically Numeric arrays of Numeric arrays? I've tried: from Numeric import * mat = zeros([2, 2], PyObject) mat[0, 0] = zeros([2, 2]) which gives ValueError: array too large for destination. It seems to be calling PyArray_CopyObject; I noticed that there was some special code to make arrays of strings work, but not for other objects. This is on Python 2.3.4 and Numeric 23.3 thanks, Garnet Chan
