Question in darts _compute_hessian

[hroken]

In the darts trainer.py, which function is _compute_hessian, shows :
"hessian = (dalpha { L_trn(w+, alpha) } - dalpha { L_trn(w-, alpha) }) / (2*eps)"
but the below is written by this :
hessian = [(p - n) / 2. * eps for p, n in zip(dalpha_pos, dalpha_neg)]
Is that wrong?

Hi @hroken , thanks for your suggestion. I think you are quite right. Could you kindly submit a PR for this?
