Hi all,
I try to use pytorch on the 2nd GPU,
`a = torch.ones(1).cuda(1)
 b = torch.ones(1).cuda(1)
 c = torch.cat((a,b),0)`

Then an error comes out:
RuntimeError: cuda runtime error (77) : an illegal memory access was encountered at /data/users/soumith/miniconda2/conda-bld/pytorch-0.1.7_1485444530918/work/torch/lib/THC/generic/THCTensorCopy.c:65
How can I fix this?
