OS: Ubuntu 18.04.3
GPU: NVIDIA Quadro P2000
Installing GPU driver and CUDA worked last week. This week CUDA no longer works. The deviceQuery script fails with the following error:
./deviceQuery Starting...
CUDA Device Query (Runtime API) version (CUDART static linking)
cudaGetDeviceCount returned 101
-> invalid device ordinal
Result = FAIL
I believe Ubuntu installed some system updates this week which could perhaps have caused the problem?
