monodepth2 added ARN

[Be997398715]

Thank you for your great project. I try to train monodepth2 with ARN module for tum dataset(most of sequences, every sequence for per 5 frame sampling, hw=640480, mono train mode with gt_depth), and I find the old monodepth2 could not handle this dataset well, cause every step the loss is 0, while monodepth2 with ARN could work a litter(loss could drop from 0.2 to 0.05 by ARN module loss funtion), where should I pay attention to when add ARN to monodepth2 as a seperate module in mono train mode?

I didn't try it directly on the monodepth2 framework. I suggest that you use our PyTorch lightning re-implementation https://github.com/JiawangBian/sc_depth_pl, where we have added the features of monodepth2 (minimum loss, auto-mask) into our baseline.

so sc_depth_pl includes all features in monodepth2 right? I will try later, thanks for your reply:)
