I am on Ubuntu 18.10. When I got my GPU (RTX 2070), I did "sudo ubuntu-drivers autoinstall". This installed the drivers. When I do "nvidia-smi" in terminal, I get this:

+-----------------------------------------------------------------------------+
| NVIDIA-SMI 415.25       Driver Version: 415.25       CUDA Version: 10.0     |

, claiming that CUDA is installed. But when I do "nvcc -V", it can't find nvcc, so I don't think I installed CUDA correctly. To be safe that I don't run into issues later, how do I remove CUDA from nvidia-smi?

  • I believe it is the way the 415.25 driver reports. I am running the same driver without CUDA installed and it shows the exact same thing. It might be a bug in nvidia-smi. – Terrance Jan 5 at 23:11

Be aware that the CUDA VERSION displayed by nvidia-smi associated with newer drivers is the DRIVER API COMPATIBILITY VERSION. It does not indicate anything at all about what CUDA version is actually installed. For example: A 410.72 driver will display CUDA VERSION 10.0 even when no CUDA toolkit is installed.
