Small issue I think, but at the sixth step of cross-validation, there is a error when batch size is set at 2 and epoch at 1:

    bad argument #3 to '?' (torch.*Tensor expected, got nil)

Hi,
I have a problem with gnuplot at :

printing.lua:92: in function 'show_figure'
script.lua:94: in function 'train_Epoch'
script.lua:161: in main chunk

The error is :

cannot open </usr/bin/gnuplot -persist > /dev/null 2>&1> in mode w. This might be because eg the executable doesn't exist, but it could also be because you are out of memory. at /home/tim/torch/pkg/torch/lib/TH/THDiskFile.c:774

I reduced the batch size at 2.
I a m trying to figure out if it is a memory problem but with a batch size of 2 and 4 Go of video memory, it is strange.
Maybe a ram pb...

Do you have any idea? Maybe all the images should not be loaded at one time at the beginning of the program.
