"'''...'''" Is designed to mean at this point, insert as many full slices (:) to extend the multi-dimensional slice to all dimensions.

print ""

a = np.arange(4).reshape(2,2)

print "a is"

print a

print "dot a"

print np.dot(a, a)

# Expand one axis in start, and tile up 2 times.

a2 = np.tile(a[None,:], (2, 1, 1))

print "a2 shape", a2.shape

a2_e = np.einsum('...ij,...jk', a2, a2)

print a2_e
