@lopuhin I also tried to implement UNet 187 unfortunately I don’t have any convergence (neither for image-to-image transforms nor for multi-class pixel-wise segmentation).
Do you have any idea what the problem could be? Do you think it maybe because of missing Batch Norm layers?
What is your experience with the different UNet models you provide? How do e.g. SmallNet, OldNet, … compare to each other?
