pagerank python implementation

I want to convert PageRank MATLAB/Octave implementation to python, but when it comes to:

a=array([[inf]])  
last_v = dot(ones(N,1),a)

there is a TypeError.

Traceback (most recent call last):
File "/home/googcheng/page_rank.py", line 18, in <module>
pagerank(0,0)
File "/home/googcheng/page_rank.py", line 14, in pagerank
last_v = dot(ones(N,1),a)
File "/usr/lib/python2.7/dist-packages/numpy/core/numeric.py", line 1819, in ones
a = empty(shape, dtype, order)
TypeError: data type not understood

The first argument to ones, the shape, should be a tuple. Change ones(N,1) to ones((N,1)).
