Noise Reduction High Error about waifu2x

[nagadomi]

Is that error in waifu2x.udp.jp? or your hosting server?

That error is being spit out through the WebUI on my own server.

Does command line tool work?

th waifu2x.lua

I don't know what’s happened. Maybe installation environment is broken.

Sorry for the late response.
I get the following when I enter that command.

What is your GPU? It seems failed to allocate video memory.
And, try

th waifu2x.lua -crop_size 32

nVidia 440GT with 1Gb VRAM

The command ends in the same result.

[nagadomi]

Maybe this issue is caused by old GPU or torch7(cunn) layer.
The simplest solution is to use a high-end GPU. 😢

[CharAznableLoNZ]

I was thinking that perhaps that was the issue.
When I can afford it, I'll get a better GPU for my server and see if that alleviates the issue.
As always, thanks for your hard work.

I have upgraded the card to a 550 TI and receive the following error.

The issue has been resolved, PCI VGA Palette Snooping was enabled on the BIOS by default. Disabling it fixes the issue.
