目前系统安装的nvidia驱动版本是390.116

CUDA sample编译完成，执行到./deviceQuery时报错:CUDA driver version is insufficient for CUDA runtime version

查看CUDA toolkit releaseNote,发现CUDA版本对显卡驱动版本有要求:https://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html
CUDA 10.1.105     >= 418.39
CUDA 9.1 (9.1.85)     >= 390.46

解决方案：升级了显卡驱动或者降低CUDA版本
CUDA 9.1要求gcc版本在ubuntu17.1下使用，需要把gcc和g++降级到6.x版本。所以没搞

安装了418.56
