About the numeric scale of the dicriminator loss

[Muming-Zhao]

Dear author,

I was using this code for my project and I found the discriminator loss is further divided by 2. I am not very clear with GAN and could you please help explain why to divide 2?

AdaptSegNet/train_gta2cityscapes_multi.py

Line 362 in fca9ff0

loss_D1 = loss_D1 / args.iter_size / 2

Thanks a lot!
