Use object arrays.

In [1]: from numpy import array

In [2]: class A(object):
   ...:     def __init__(self, x):
   ...:         self.x = x

In [3]: some_As = array([A(1), A(2), A(3)], object)

In [4]: some_As
array([<__main__.A object at 0x212af70>, <__main__.A object at 0x212ae30>,
       <__main__.A object at 0x212ac90>], dtype=object)

You can't.
