Your origin image size is 96x96?
Your origin image size is 96x96?
train->original's image size is 256x256, after run scripts/run.py, the image in train->GT is 128x128. I think is imgproc.py->random_crop_torch to crop the image to 96
Generally speaking, If GT image size is a multiple of 3, there is no problem.

I change
lr_top = random.randint(0, lr_image_height - lr_patch_size)
lr_left = random.randint(0, lr_image_width - lr_patch_size)
to
lr_top = random.randint(0, lr_image_height - lr_patch_size - 1)
lr_left = random.randint(0, lr_image_width - lr_patch_size - 1)
and it can work with scale==3,although i dont know why
There is a problem with the dismantling script, which has now been fixed
Hello,
The code worked well for me when the upscale factor was a multiple of 2. Thank you for providing these solutions. However, when I changed it to 3, I encountered some issues.
Firstly, in the
model.py
file, within the_UpsampleBlock
class, I noticed that the parameters ofnn.PixelShuffle
need to be changed from2
to theupscale_factor
.Furthermore, I encountered a problem related to
pixel_loss = pixel_criterion(sr, gt)
. The error message "The size of tensor a (96) must match the size of tensor b (95) at non-singleton dimension 2" might be due to the image cropping process when the upscale factor is 3. It's possible that the cropping process introduces some floating-point discrepancies. However, the code structure is quite complex, and I'm unsure if I have the ability to fix it on my own.Could you possibly help me address this issue so that the code works seamlessly with an upscale factor of 3, thank you?
