Cant get depth supervision to work

[juuso-oskari]

Hi @ashawkey,

I'm trying to get the depth supervision to work, but so far its only making perfomance worse for me. I'm wondering why the depth is not normalized with the weights_sum? Because depth is calculated as weighted sum timestep_i * weight_i, shouldn't it be divided with weights_sum, since we can't be sure that weights_sum is 1?
