在Azure 申请了一台 K80的虚拟机,redhat7 系统。在安装cuda时,可以成功,但在执行nvidia-smi 时,总是报错:

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

以前经常在centos 上安装cuda ,已经非常熟悉,这次按照原来的讨论安装为什么总报错,排查后,发现:Azure给的系统为最小系统,缺少许多必要的基础环境包,所以必须自己手动安装,总结如下:


1、安装GCC,

yum install gcc*

2、装dkms

wget http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-9.noarch.rpm

 rpm -ivh epel-release-7-9.noarch.rpm

yum install --enablerepo=epel dkms

3、安装kernel 开发包等

yum install kernel*

4、安装cuda

5、挂载驱动:

modprobe nvidia

6、然后可以安装其他包了,anaconda,tensorfolw 等
