[Numpy-discussion] Bilateral filter
Sun Mar 1 13:36:33 CST 2009
1. "dimensions" is a field in the C struct, that describes the array object.
2. Is there a chance that the header file numpy/arrayobject.h belongs to a
different numpy version that you run?
I am not very experienced with cython (I suppose that Stefan has some experience).
As you said, probably the cython list is a better place to look for an answer. I would be happy to see how this issue resolved.

Yeah... and I just tried that again, with the same results. I have no
idea what could be going wrong. E.g. why would 'cimport numpy as np'
not add np to the namespace on my machine whereas it does so on yours...
Also, I assume that constructs like:
cdef int i, dim = data.dimensions
are some special numpy-support syntax that's supposed to be added by
the cimport numpy line? (Because numpy arrays don't expose a
'dimensions' attribute to python code...) It's like for some reason on
my machine, cython isn't building its numpy support correctly. Which
is understandable in the light of the fact that cython can't pass the
numpy tests on my machine either. Odd indeed. Maybe I'll try on the
cython list, since you guys seem to have demonstrated that the problem
isn't in the bilateral code!
