Question about the code

Hi , in your paper , there is no descriptions about the "unfold " operation, but I found in your code. Can you give me some guidance why using unfold operation? Looking forward to your reply, thanks!
Meta-SR-Pytorch/model/metardn.py
Line 129 in 8aec6e1
Hi, do you see any errors in meta.py, saying 'ValueError: only one element tensors can be converted to Python scalars'? Thanks!
Sorry, I haven't run meta.py. But I think there may be something wrong with your input data
Hi,
I think the unfold function is used for color channels. There are three color channels, so you have to select the tensors with a stride of three.
Hi, i think the unfold is to extract the k x k patch around every pixel in the up_x, so as to do the matmul with the local weight, just like the right bottom part of Figure 1 in the paper.
