nvidia-cuda-toolkit install and uninstall nvidia-smi

apt install nvidia-cuda-toolkit

# apt install nvidia-cuda-toolkit

but after that, the nvidia-smi cannot be working.

(launcher) root@ip-172-31-33-152:~# nvidia-smi
Failed to initialize NVML: Driver/library version mismatch

So, I delete nvidia-cuda-toolkit again.

(launcher) root@ip-172-31-33-152:~# sudo apt-get purge --auto-remove nvidia-cuda-toolkit

nvidia-smi can work now.
