Can you do:
require 'fbcoco'
in the interpreter and see if it gives a better error trace?
Hi guys, ahh, now I see, there are 2 "coco" modules required. Just to let you know the context, I am wrapping all the torch packages in the Gentoo ebuild system which are available ArchenRoot Gentoo Overlay. It is still very experimental and some of modules I had to install still manually as would like to have quickly Multipathnet available.
I can confirm that I can do:
th> require 'coco'
{
TensorTable : {...}
MaskApi :
{
merge : function: 0x406d7698

frPoly : function: 0x41b1d960
drawLine : function: 0x41b1d988
drawCirc : function: 0x415cdad0
}
CocoSeg : {...}
libmaskapi : userdata: 0x407a0d00
CocoApi : {...}
}
but when trying to test fbcoco (found in demo.lua), it is not available:
th> require 'fbcoco'

I didn't know there are 2 coco libraries, but understand first is standard one which consists of following files:
ares coco # ls
CocoApi.lua env.lua init.lua MaskApi.lua
and the second one -> fbcoco, which is only referenced directly in this repository and I was not able to find it anywhere else. When I look at fbcoco.lua file I understand it refers to some underlaying files. So what I tried to do now was install manually fbcoco related files as following into my lua subsystem, where all Torch modules are installed and working:
ares 5.1 # pwd
/usr/share/lua/5.1
ares 5.1 # tree fbcoco
fbcoco

├── BatchProviderROI.lua

I am now going to give it a try.
So when I try now to execute require I get:

I just finished the whole stack installation (half via ebuilds, half from sources) on Gentoo system. Thing is that any lua file I try to execute via th something.lua is ending as:
I think I am missing something in general, but the error doesn't not lead me to resolution...
Thanks for any hints.
