Crash in training #21

I attempted training (kgs data) with train.sh I installed most recent version of torch, and cuda 8.0. Training seem to end soon with error as below:

rl.Dataset.__init(): #forward model = 2048, batchsize = 256
| IndexedDataset: loaded ./dataset with 26814 examples
rl.Dataset.__init(): #forward model = 2048, batchsize = 256
rl.Dataset.__init(): forward_model_init is set, run it
