Hi, in dudenet you have done experiments for real noisy images also. However, when I provide grayscale images to model it shows below error
RuntimeError: Given groups=1, weight of size [3, 6, 1, 1], expected input[3, 4, 256, 256] to have 6 channels, but got 4 channels instead

so can you please let me know why this error occur or what need to be changed in the code
