Btw, I just wanted to file a bug at PySide, but it might be alright at
their end, because I can do this:
from PySide import QtGui
image = QtGui.QImage('/home/peter/code/pyTools/sandbox/images/faceDemo.jpg')
a = image.bits()
del image
a

I probably did something wrong, but it does not work how I tried it. I
am not sure if you meant it like this, but I tried to subclass from
ndarray first, but then I do not have access to __array_interface__. Is
this what you had in mind?
from PySide import QtGui
import numpy as np
class myArra
Brilliant thanks, I will try out the "little class" approach.

Hi,
I as the title says, I am looking for a way to set in python the base of
an ndarray to an object.
Use case is porting qimage2ndarray to PySide where I want to do
something like:
In [1]: from PySide import QtGui
In [2]: image =
QtGui.QImage('/home/peter/code/pyTools/sandbox/images/faceDem
there isn't that much code in numpy that profits from modern x86
instruction sets, even the simple arithmetic loops are strided and thus
unvectorizable by the compiler. They have been vectorized manually in
1.8 using sse2 and it is on my todo list to add runtime detected avx
support.

We have such benchmark in Theano:

Jerome, Thanks for the swift response and tests. Crikey, that is a significant
difference at first glance. Would it be possible to compare a BLAS computation
eg. matrix-vector or matrix-matrix calculation? Thx!___

Probably a loaded question but is there a significant performance difference
between using MKL (or OpenBLAS) on multi-core cpu's and cuBLAS on gpu's. Does
anyone have recent experience or link to an independent benchmark?

Have you tried on an Intel CPU? I have both a i5 quad core and an i7 octo
core where I could run it over the weekend. One may expect some compiler
magic taking advantage of the advanced features, specially the i7.
