@kshitij12345 I think it's because of the design of Python backward API in
MXNet. When you specify `variables=x`, MXNet will only compute

I don't think this part is correct.

@kshitij12345 I have some question about the equation `expected_head_grad =
(grad_op(x) * head_grad_grads).asnumpy()` in your test.

I did some more probing. I think the reason that head_grads.grad being all
zeros is the variable head_grads was not specified during the
