Can't evaluate pretrained model

[mees]

Hi, when I try to evaluate the pretrained model with 'th evaluate_model.lua 'I get following error:

/home/meeso/torch/install/bin/luajit: /home/meeso/torch/install/share/lua/5.1/nn/Container.lua:67: 
In 3 module of nn.Sequential:

Any idea how to solve it?

Did you solve it? I have the same problem.

I solved the problem by commenting out lines 39,58,59,78,79,80,81.
Maybe the calculation of the loss is not needed.
