I had a similar issue, but explicitly specifying the model directory with the -m flag fixed it. I'm getting garbled image outputs though.
My old issue:

fopen models-cunet/noise2_scale2.0x_model.param failed
fopen models-cunet/noise2_scale2.0x_model.bin failed
Segmentation fault

Tried adding -m, but issue don't change. Commands are:

>waifu2x-ncnn-vulkan -i i.jpg -o o.png -n 2 -s 2 -m models-cunet
>waifu2x-ncnn-vulkan -i i.jpg -o o.png -n 2 -s 2 -m models-upconv_7_anime_style_art_rgb

I encountered similar situation, and I fount that I have to cd to the path of the program to make it work under windows(Windows Server 2019 DC). And everything is fine under Linux.

[XCanG]

Wow, that really fix issue, it work for me if I call command in same folder with exe.

[symant233]

Same here, but I'd prefer call the .exe in another path, hope author could fix that soon... @nihui

This still happens to me, on Linux.
fopen models-upconv_7_photo/noise1_scale2.0x_model.param failed
fopen models-upconv_7_photo/noise1_scale2.0x_model.bin failed

When I cd in the directory containing models, instead, everything works.
This issue does not concern cunet's bins and params, which can be opened from anywhere.
I am using release 20200606.

Can confirm this still happens in Windows on 20200606 as well.

What I ended up doing is drop a batch script file as such in the folder:

@echo off
cd /d [>waifu program path<]
waifu2x-ncnn-vulkan -i %1 -o %2

This works from any command prompt window when added to PATH.

try the latest artifact build in CI

I tried the artifact from https://github.com/nihui/waifu2x-ncnn-vulkan/runs/909102954 and it seems to be working!
Here's the windows-2019 build: https://github.com/nihui/waifu2x-ncnn-vulkan/suites/962691968/artifacts/12130511

Still an issue for me with latest master on Linux:
