When I run the code torch.cuda.is_available(), I meet the error as below:
THCudaCheck FAIL file=torch/csrc/cuda/Module.cpp line=109 error=30 : unknown error
Traceback (most recent call last):

    if torch.cuda.is_available():
  File "/usr/local/lib/python2.7/dist-packages/torch/cuda/__init__.py", line 30, in is_available
    return torch._C._cuda_getDeviceCount() > 0
