This package provides the cli version of waifu2x-caffe. A readme for all of the flags is located in /usr/share/docs/waifu2x-caffe/README. The models are located at /usr/share/waifu2x-caffe/models.

@sommio Feel free to alter the PKGBUILD to have the older versions of cuda and cudnn on your local system. Once you have cloned this repository, make the necessary changes by updating the fields in the depends section to the older versions. Then you can commit that change to your local git repo. What this will do is allow for any changes in the future to be merged with the changes you added and you may not need to make them every time I release an update.

If the older versions work let me know.

Not only is this compatible with older nvidia gpu's, but caffe has higher performance in cudnn7 than cudnn8!

Can you make a waifu2x-caffe pkgbuild that uses cuda10 and cudnn7? Thanks!

@ginnokami The first time I tried to use this program, it seems that my graphics card does not work with the latest CUDA...

@sommio Has this application ever worked for you or is this the first time you are trying to use it? Taking a look at CUDNN Capability Matrix shows that your CUDA capability may no longer be supported on the newer CUDNN releases.

Are you able to run the tool without CUDNN and just CUDA? That would be just removing the -cudnn option.

@ginnokami I tried using the makechrootpkg build, but it still doesn't work

mkarchroot $CHROOT/root base-devel
makechrootpkg -c -r $CHROOT

my log and pkg: Google Drive

@ginnokami Yes, I am using the latest version of cudnn and cuda and pkgbuild, but my nvida driver version is 470xx.

@sommio are you on the latest version (my last compile was on 2/7 when I updated to support building in chroot)? I am able to successfully run using cudnn using the following command:

waifu2x-caffe -p cudnn --gpu 0 -m noise_scale -n 2 -c 256 -h 1440 -i in.jpg -o out.jpg | nkf
