I can't seem to be able to load packages in qlua:

nicholas@xps:~$ qlua -limage
qlua: module 'image' not found:
    no field package.preload['image']
    no file '/home/nicholas/nikopia/image/init.lua'
    no file '/usr/local/lib/lua/5.1/image.so'
stack traceback:
    [C]: at 0x7faf95d56a20
    [C]: at 0x7faf95b1def0

I installed qlua with

sudo luarocks install qtlua

I installed image with

sudo luarocks install image

Its not just the image package:

nicholas@xps:~$ qlua -ltorch
qlua: module 'torch' not found:
    no field package.preload['torch']
    no file '/home/nicholas/nikopia/torch/init.lua'
    no file '/usr/local/lib/lua/5.1/torch.so'
stack traceback:
    [C]: at 0x7fcc36901a20
    [C]: at 0x7fcc366c8ef0

qlua works fine otherwise:

nicholas@xps:~$ qlua
Lua 5.1  Copyright (C) 1994-2008 Lua.org, PUC-Rio

post your OS and other relevant details.
Also, let me know if you have other versions of lua and luarocks on your system.

soumith commented

also, post the output of "luarocks install qtlua"

your package.path is being initialized super wrong, as you see. I actually dont know why, and I cant reproduce your issue on Ubuntu 14.04, 14.10, RHEL 6.3, or OSX. I dont have a 12.04 machine, will see if someone else can comment.

In the meanwhile, you can start a qlua, and manually set the package.path and package.cpath to what th outputs.

nicholas-leonard commented

Okay that worked. Thanks @soumith.
Not sure if this is related, but there isn't any difference between :

image.display{image={image.lena(), image.lena()},gui=true}

and

image.display{image={image.lena(), image.lena()},gui=false}
soumith commented

closing because i cannot reproduce!

nk0307 commented

have the similar problem. though reset the LUA_PATH and LUA_CPATH, it is still not working. the thing might be the path of package of torch.
