I've adopted this package and repurposed it. It now installs the original Lua/Torch7-based waifu2x. The C++ rewrite seems to have been discontinued, and the original is still being maintained. If you want to use the C++ version, install waifu2x-converter-cpp-git instead.

Cannot compile successfully with encountering this problem:

Can't install because torch7-cunn-git requires gcc54, which is not available anymore.

==> Error: Could not find all required packages: gcc54 (Wanted by: waifu2x-git -> torch7-cunn-git)

After trying again a few times (not sure what I changed exactly) I don't get this error anymore, but I could not compile torch7-cutorch-git unless I installed gcc5.

Fortunately, I found gcc-4.9 on the manjaro repos and used that to compile torch7-cutorch.

Alternatively, one could use the gcc shipped with cuda in /opt/cuda/bin/gcc I guess...

After all the trouble of compiling these deps, it works fine.

Thank you kindly!

eigengrau: I've added torch7-cudnn-r7-git as an optdepend. Haven't looked into model training myself yet, but I've added those packages you say are required for it as optdepends as well for now. Perhaps I'll put up a PKGBUILD for lua51-csnappy later too if I have time.

The data conversion step requires lua51-cjson and lua51-csvigo-git. lua-csnappy appears to be required, as well. Unfortunately it’s not provided by any AUR package currently.

Additional note: this is currently missing the torch7-optim-git dependency, which is required to train models.

Thanks for maintaining this! Would it make sense to add torch7-cudnn-r7-git as an optdepend? This seems to be what’s required to use the CUDNN backend (-force_cudnn 1).

BTW, I’m not quite sure as to what the supposed differences between the CUDNN and the default backend are. The regular backend seems to utilize CUDA as well, but CUDNN gives me slightly better performance. Not sure if this is uniformly the case though.

You are right, it is only a library now. To use waifu2x directly we may use `waifu2x-converter-cpp`.

I will remove `provide: waifu2x-converter-cpp` in the future.
