Failed on GPU with AWS EC2 g2 instance

1

I installed pytorch on AWS ec2 g2 instance ( with cuda 7.5)

Everything runs all right while on CPU, but when I tried to run on GPU. It threw the message below.
Tried to google the err msg but couldn’t find it
Thanks for any help!

torch.cuda.is_available()
THCudaCheck FAIL file=torch/csrc/cuda/Module.cpp line=108 error=30 : unknown error
Traceback (most recent call last):

Hai,
Yes. It used to work fine. No longer does due to driver change by NVIDIA.

This article explains the issue.

“GPU-accelerated OpenGL onAmazon Web Services (AWS G2 instances) with NVIDIA GRID K520/K340 No Longer Works”

This is a known issue.

NVIDIA GRID drivers introduced a change in build 340. Earlier NVIDIA drivers enabled OpenGL sharing but later versions do not. NVIDIA reports that the AWS behavior is as intended. NVIDIA OpenGL over RDP/ RDSH is only supported on workstation (Quadro) / NVS products. The GRID K520 card that is on Amazon’s G2 instances is not a workstation product unlike GRID K2.
Thanks,
Riya,
