Input: X, Y = getfake(50, 2, 0.3)

tmp [[ 0.41137779 1.77428079]] <NDArray 1x2 @cpu(0)>

X[i,:] [ 0. 0.] <NDArray 2 @cpu(0)>

X <NDArray 50x2 @cpu(0)>

`Y [ 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.

                                  1. 0.
                          1. 0.] <NDArray 50 @cpu(0)>`

Output: ValueError: operands could not be broadcast together with remapped shapes[original->remapped]: (1L, 2L) and requested shape (50L,)

I think the tmp should be modified as tmp = nd.random_normal(shape=dimensions).
