I’m using:
PyTorch 0.4
Cuda: 9.1
the error message:
RuntimeError: cuda runtime error (10) : invalid device ordinal at /opt/conda/conda-bld/pytorch_1524590031827/work/aten/src/THC/THCGeneral.cpp:70
Any idea how to fix it?
update:
torch.cuda.device_count()
returns  0
and it’s weird. here is my nvidia-smi:

Fixed by reinstalling CUDA/CUDNN/CONDA… good luck:)
