No MultiLabelMarginCriterion about cunn HOT 6 OPEN

Had written this code a long time ago, just made a PR for it now:
#153

I don't have a good unit test for it though. If someone can write a quick one that would be great.

@clementfarabet Hi, I really want to use the MultiLabelMarginCriterion on GPU. I have found your fork of cunn, however, I do not know how to use it. I mean I only know installing packages using luarocks install... Could you please tell me how to use your code?

from cunn.

hey Jireh,

You can do:

git clone https://github.com/clementfarabet/cunn -b master
cd cunn
luarocks make rocks/cunn-scm-1.rockspec

Then you will get his version of cunn that has GPU MultiLabelMarginCriterion

@soumith Thank you for your reply. However, I just tried exactly the same command you suggested, but failed with this error:

make[1]: *** [CMakeFiles/cunn.dir/all] Error 2
make: *** [all] Error 2

Do you know the possible reasons?
Yesterday I have installed iTorch using the similar way, and succeeded.
