Cannot run facedetector about demos

[soumith]

the face detector might be a little outdated. try the ones in this repo:
https://github.com/e-lab/torch7-demos

Ah yes it seemed to be a little old. Thank you.
Btw if now I do from terminal (in the face-detector-elab folder) :

qlua run.lua
==> processing options
qlua: /usr/local/share/lua/5.1/torch/File.lua:232: read error: read 1 blocks instead of 25602
stack traceback:
[C]: at 0x7f699fd06620
[C]: in function 'read'
/usr/local/share/lua/5.1/torch/File.lua:232: in function </usr/local/share/lua/5.1/torch/File.lua:163>

And if I run it inside qlua :

==> processing options
/usr/local/share/lua/5.1/pl/lapp.lua:321: attempt to get length of local 'arg' (a nil value)
stack traceback:
/usr/local/share/lua/5.1/pl/lapp.lua:321: in function 'lapp'
run.lua:26: in main chunk

Actually there are errors like that for every demo.

i removed the face detector demo, it was broken and not working.

Ok, sorry for opening too much issues but I was searching for some working demo for face detection to actually looking at the code and learn some trick.

When I was TA for Davi's class I copied Clement's face-detector demo and fixed it so it runs on the new torch / lua:

you can take a look at person-detector demo which is almost the same as face-detector. The network there doesn't perform well but there are many tricks.

Thanks @Aysegul @jonathantompson
I'll take a look at both

Ok @soumith the code works, I had something old for sure.
Apart from that, are this and the person-detector good for learning how to use the multiscale pyramid technique? I mean for a newbie. Sure there are things more complex, like the road-net for example.

I think they are good. You can display the middle steps with image.display to see what pyramid does.
