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

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

print "a2 shape", a2.shape

print "einsum dot product over higher dimensions"

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

print a2_e
