Have problem when setup.

@fqnchina thanks for share the great paper and code.
Machine environment is ubuntu16.04; torch 7; cuda 8.
When I set up the environment to run this command
th test_smooth.lua
I got the error message:

torch/install/share/lua/5.2/nn/EdgeComputation.lua:17: attempt to call field' EdgeComputation_updateOutput' (a nil value)
stack traceback:
~/torch/install/share/lua/5.2/nn/EdgeComputation.lua:17: in function <~/torch/install/share/lua/5.2/nn/EdgeComputation.lua:9>

Edited file ~/torch/extra/nn/init.lua

require('nn.Jacobian')
require('nn.SparseJacobian')
require('nn.hessian')
require('nn.test')

require('nn.EdgeComputation')
require('nn.EdgeDetector')
require('nn.SmoothAndEdgeTerm')

return nn

If I add "TH_API" before "void" , then will receive another error.

I can't find the solution for this, could you help me? Thanks a lot.

I write in this way , it seems work.

TH_API void  THNN_(SmoothAndEdgeTerm_updateGradInput)(
		THCState *state, 
		THCudaTensor *input_cnn, 
		THCudaTensor *smooth_mask, 
		THCudaTensor *target_edge_mask, 
		THCudaTensor *weight, 
		THCudaTensor *gradInput, 
		float sigma_color, 
		int window_size, 
		float lp, 
		int w_L2);

Is there anyone who successfully run this code? I try to run it but failed due to environmental setup.
