THCudaCheck FAIL file=/opt/conda/conda-bld/pytorch_1513368888240/work/torch/lib/THC/generic/THCStorage.c line=82 error=2 : out of memory

Hi,

i'm trying to run demo_server.py and i get this

```
THCudaCheck FAIL file=/opt/conda/conda-bld/pytorch_1513368888240/work/torch/lib/THC/generic/THCStorage.c line=82 error=2 : out of memory
Segmentation fault (core dumped)
```

What should I do?

Regards,
Huy

Start by reproducing the failure when running demo_server.py and compare the reported THCStorage.c line 82 error with the available GPU memory and runtime environment. Done means identifying the cause of the out-of-memory failure and documenting a verified way to run the demo without the subsequent segmentation fault.
