Looking at the definition of "ones":

def ones(shape, typecode='l', savespace=0):
    """ones(shape, typecode=Int, savespace=0) returns an array of the given
    dimensions which is initialized to all ones. 
    return zeros(shape, typecode, savespace)+array(1, typecode)

It looks like you could try a=zeros(shape)+initial_val instead.

Hm.. I might do some experimenting.
