About log operator in LMC equation

Thank you! but I still have a question... in line 280, the code is: ``` net_grad = data['points_2d'].grad.detach() loss_per_pix = loss_per_pix.detach() net_grad = net_grad / ((grad_scaler._scale * (correction * loss_per_pix).unsqueeze(1))+...

About log operator in LMC equation

Here is my understanding: 1. approximate correction(x) = Q(x) thus → ▽log(Q(x)) = ▽Q(x)/Q(x) = ▽correction(x)/correction(x) I dont know why to multiply loss_per_pix again given that there is `loss_per_pix.mul_(correction)` in...
