[Numpy-discussion] NumPy on 64-bit Linux (Opteron)

[Bruce Southey]

Hi, 
Yes (Python 2.3.3 [GCC 3.3.3 (SuSE Linux)]) with Numeric 23.7 (clean install). 
 
It is to do with the function: 
extern PyObject * PyArray_Reshape(PyArrayObject *self, PyObject *shape) 
 
the variable s_known is not being assigned correctly (gets set to zero). I 
think that stems from this call that doesn't set the dimensions correctly: 
 
PyArray_As1D(&shape, (char **)&dimensions, &n, PyArray_LONG) 
 
dimensions in the second loop has value 0. 
 
Regards 
Bruce
