This works fine on Windows and Mac; the problem only seems to happen on Linux:

Can you import flib module directly? That is, what happens if you execute cd .../PyMC PYTHONPATH=. python -c 'import flib'

It gives a "no module named flib" error.

Dear list, I'm using old numarray C api with numpy. It seems that there is a bug when using the PyArray_FromDims function. for example, if I define : acc = (PyArrayObject *) PyArray_FromDims(pos->nd,pos->dimensions,pos->descr->type_num); where pos is PyArrayObject *pos; (3x3 array) when using return PyArray_Return(acc); I get array([], shape=(3, 0), dtype=float32) It is possible to make everything works if I use the following lines instead : int ld[2]; ld[0]=pos->dimensions[0]; ld[1]=pos->dimensions[1]; acc = (PyArrayObject *) PyArray_FromDims(pos->nd,ld,pos->descr->type_num); So, the problem comes from the pos->dimensions. Is it a known bug ? (I'm working on a linux 64bits machine.) Cheers, yves

Hi,

What type is pos->dimensions in your case ? It may be long (64bits long) instead of the expected int (32bits) or something like that ?

yes, pos->dimensions is a 64bits long while PyArray_FromDims expects 32bits int. Why is it so ?

Dear list,

I'm using old numarray C api with numpy. It seems that there is a bug when using the PyArray_FromDims function.

for example, if I define : acc = (PyArrayObject *) PyArray_FromDims(pos->nd,pos->dimensions,pos->descr->type_num);

where pos is PyArrayObject *pos; (3x3 array)

when using return PyArray_Return(acc); I get array([], shape=(3, 0), dtype=float32)

It is possible to make everything works if I use the following lines instead : int ld[2]; ld[0]=pos->dimensions[0]; ld[1]=pos->dimensions[1]; acc = (PyArrayObject *) PyArray_FromDims(pos->nd,ld,pos->descr->type_num);

So, the problem comes from the pos->dimensions.

Is it a known bug ?

Cheers,

yves

PyArray_FromDims is backward compatible Numeric API which did not support 64-bit correctly.

PyArray_SimpleNew is the equivalent that accepts 64-bit dimensions information and is what you should be using.

ok, excellent ! thanks for the answer. yves
