train.lua cannot find cutorch

When I'm trying to run the training in the base image, I get the following issue:

Hi,

cutorch is the CUDA version of the library.
This base image is for CPU only, so you have to append
-gpu -1
on the command line (train.lua, sample.lua) to force CPU only mode.
See https://github.com/jcjohnson/torch-rnn/blob/master/doc/flags.md
