在 Linux 主机上配置了很多次 Cuda/CuDNN 的运行环境，在此记录下用到的脚本命令以复用。
特别提醒，先了解清楚 GPU 卡的型号，查清与主机 Linux 内核兼容的驱动程序、Cuda 和 CuDNN 的发行版。

1. NVIDIA 驱动安装
# WIKI: https://download.nvidia.com/XFree86/Linux-x86_64/375.20/README/installdriver.html wget http://us.download.nvidia.com/tesla/384.145/NVIDIA-Linux-x86_64-384.145.run && chmod u+x NVIDIA-Linux-x86_64-384.145.run && ./NVIDIA-Linux-x86_64-384.145.run --silent --dkms --accept-license
2. 打开持久模式
nvidia-smi -pm ENABLED # WIKI https://docs.nvidia.com/deploy/driver-persistence/index.html
4. GPU 设备信息查看
