RuntimeError: cuDNN error: CUDNN_STATUS_BAD_PARAM

[RaySunWHUT]

hi, Mr. sefibk,

Thanks for your work, and if I use the "Blind data generator" to generate degradation images, the kernelGAN can estimate the correct kernel. But if the use a self-created disk kernel, and I run the code this a low-resolution image that downscales with the disk SR kernel. The code will occur error like this:

the disk kernel I used can be visualized like this:

and the kernel details is this:

and by the way, if you can solve the last issue I mentioned, I will be very grateful!

I think it is related to the CUDNN issue. I can't think of a reason why the type of kernel should affect the run. In fact - the algorithm is unaware of the kernel itself...
