You should see the training file. He gets it correctly but just inverses the index. Here the main_train.py, line 162.
The index is [1] then [0]
batch_x, batch_y = batch_yx[1].cuda(), batch_yx[0].cuda()
@ngcthuong Thank you for your reply, but there are no 162 lines in the main_train.py file. I didn't find this code.
batch_x, batch_y = batch_yx[1].cuda(), batch_yx[0].cuda()
FYI
@ngcthuong I am referring to the keras version rather than pytorch here !
The network output is still noise, the only difference is the author subtracts noise from inputs to get the estimated clean image, as you can see in line 76:
x = Subtract(name = 'subtract' + str(layer_count))([inpt, x]) # input - noise
Actually there are no difference, since the idea of residual still resides here.

ok, I got it! Thanks! @bittergourd1224
noise = np.random.normal(0, args.sigma / 255.0, batch_x.shape) # noise
batch_y = batch_x + noise
yield batch_y, batch_x
Does these lines of code mean that the labels are clean pictures rather than noises? However, in the paper 'Beyond a Gaussian Denoiser: Residual Learning of Deep CNN for Image Denoising ', the noise are set as labels. Is the code correct?
