no support CPUS without AVX?

That's exactly what waifu2x-opt is.

I can't get it work, it always terminates with this error
terminate called after throwing an instance of 'ZimgError'
Aborted (core dumped)


My script
import vapoursynth as vs
core = vs.get_core()
ret = core.imwri.Read('foo.jpg')
ret = core.waifu2x.Resize(ret)
ret.set_output()

32- or 64-bit? It uses an enormous amount of memory, in 32-bit it might be exceeding the limit with a large input.

I'm running it on Linuxmint x64, Vapoursynth and it's plugin are installed from djcj's PPA.

What's the format, width and height of your input image?
it's some problem related to the zimg part, and in this case only the chroma is processed with zimg, so you can try a GRAY clip to see if the error still exists.
By the way, this plugin should be deprecated since Waifu2x-w2xc (http://forum.doom9.org/showthread.php?t=172390) is a better choice. The latter is faster even in pure CPU mode, with much less memory consumption.
