Ops, this seems a bug with your numpy version:
In [46]:array1 = numpy.zeros((10,10),int)
In [47]:array1.itemset((5,5),9)
In [48]:array1
Out[48]:
array([[0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[0, 0, 0, 0, 0, 9, 0, 0, 0, 0],
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0]])
In [49]:array1.item(5,5)
Out[49]:9
In [50]:numpy.__version__
Out[50]:'1.0.2.dev3546'
So, this seems solved in SVN.
