GPU安装制定kernel路径

在centos7.2 安装cuda-8 出现报错：

that the kernel source packages are installed and set up correctly.
If you know that the kernel source packages are installed and set up correctly, you may pass the location of the kernel source with the '--kernel-source-path' flag.

解决方法：

sudo yum install epel-release
yum install --enablerepo=epel dkms
