require 'cunn' and 'cutorch' in CPU mode

[NightFury13]

The eval.lua script expects a gpuid (-1 for CPU) option, but running in CPU model also requires loading the 'cutorch' and 'cunn' packages. This leads to an error on startup itself and simply commenting those out and running the code in CPU mode fails on loading the pretrained_model_lstm.t7 file. I am expecting there is a workaround for this?

PS : I have cunn and cutorch packages installed (no GPU though)
