Good day all,
I know there have been many answers for similar questions, however I havn’t found a solution. My cuda_is_available() is returning False, but weirdly it used to return True with the same configuration. The code is running on a GPU cluster. I was wondering if any people wiser than me can identify anything wrong with the following configuration:
PyTorch version: 1.4.0
Is debug build: False
CUDA used to build PyTorch: 10.0
ROCM used to build PyTorch: N/A

OS: CentOS Linux 7 (Core) (x86_64)
GCC version: (GCC) 4.9.0
Clang version: Could not collect
CMake version: Could not collect

Python version: 3.6 (64-bit runtime)
Is CUDA available: False
CUDA runtime version: 10.0.130
GPU models and configuration:
GPU 0: Tesla V100-PCIE-16GB
GPU 1: Tesla V100-PCIE-16GB
GPU 2: Tesla V100-PCIE-16GB

Nvidia driver version: 418.40.04
cuDNN version: Could not collect
HIP runtime version: N/A
MIOpen runtime version: N/A
