have you installed torch http://torch.ch?

[bemoregt]

Yes, of course.

[szagoruyko]

what is the output of which luarocks

[bemoregt]

$ which luarocks
/Users/sgi/torch-cl/install/bin/luarocks

Thanks~

[szagoruyko]

you should try with official torch distro, I'm not sure why torch-cl doesn't know about cv. cc @hughperkins

Hi @bemoregt Can you raise an issue at https://github.com/hughperkins/distro-cl/issues/new please?

[hughperkins]

Note that luarocks install cv runs for me. Or at least, finds something, clones it, tries to install it, fails because sudo apt-get install opencv installs 2.4.9.1. this is on ubuntu 16.04.

I'll see if I can get hold of opencv 3.1, and at least confirm it installs on ubuntu.

But... osmseting that occurs to me. should the quotes not be around the OpenCV_DIR assignment? something like perhaps:

"OpenCV_DIR=/usr/local/Cellar/opencv3/3.1.0/share/OpenCV" luarocks install cv

[hughperkins]

(Also, did you make sure to do source ~/torch-cl/install/bin/torch-activate just before running hte luarocks install command?)

On ubuntu 16.04 it builds ok for me. What I did:

# downloaded opencv
# unzipped
mkdir build
cd build
ccmake ..
# 'c' for configure
# set pretty much everything to 'OFF', except 'ml' and 'img' https://gist.github.com/hughperkins/c2ee47a0a6629d7a96969f12ec6c01da
# quit out from ccmake 
cmake ..
make -j 4
source ~/torch-cl/bin/activate
OpenCV_DIR=/home/user/Downloads/opencv-3.1.0/build luarocks install

Thats it!

So, it does install ok, on ubuntu. In your case... I think maybe an enviornment issue? But ...as for what .... ???

Thanks a lot.
