Re: can't find the code for ClassNLLCriterion_updateGradInput

[Jonghoon Jin]

The ClassNLLCriterion_updateGradInput is being triggered if input is CUDA tensor.

https://github.com/torch/nn/blob/master/ClassNLLCriterion.lua#L54

and it is defined here

https://github.com/torch/cunn/blob/master/ClassNLLCriterion.cu#L125

Hello!

In the ClassNLLCriterion.lua code, there's a call to a function ClassNLLCriterion_updateGradInput.
I though that I may found it in a file like ClassNLLCriterion.c but there is not. So I wonder what is executed during the call of ClassNLLCriterion_updateGradInput?

Can anyone open my eyes on this ?
