NYI call return type in cv.imread

[achsvg]

Hello,

When I try to call cv.imread, I get the following error:

torch/install/bin/lua: ...ng/torch/install/share/lua/5.1/cv/imgcodecs/init.lua:27: NYI: call return type

Can anyone tell me where this might be coming from?

Thanks

Hi!

What are your OS and CPU architecture?

[achsvg]

OS is ubuntu 14.04 and CPU is 64 bit.

Hmm.

1. Do other functions also crash? Have you tried running th demo/flann.lua or th demo/SVM.lua? Do they run correctly?
2. Looks like you're running torch/install/bin/lua. Did you install Torch with Lua instead of LuaJIT? Try running torch/install/bin/th or luajit instead

None of the functions work, the demo does not work for me either with the same error :(

I am running the scripts with th and compiled torch with luajit too, even though I did install torch with Lua5.1 previously, I re-compiled it since then with luajit...
Will try with a fresh install, let me know if you have any more ideas, thanks.

Thanks, will be waiting for your result. I'll see if I can do something with FFI. That's really a strange error.

Ok it works now, I must have screwed up something in my torch installation...
Thanks!

Hey I am also facing a similar error. Can you tell how you rectified this?

[arunpatala]

I installed torch using Lua5.2 instead of LuaJIT
TORCH_LUA_VERSION=LUA52 ./install.sh
Can that cause the problem

i also meet the same poblem so do you have any solutions

@ganliqiang Try installing Torch with LuaJIT instead of Lua 5.x, or see #189.
