No MultiLabelMarginCriterion

[korkinof]

Hi guys,
I noticed there is no cunn implementation of this criterion.
Do you plan to implement that any time soon?
We could try implementing it ourselves otherwise or just keep the criterion on CPU.
Best,
D.

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?

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.
