linux验证cuda安装成功_linux # centos # 安装cuda

注意: 千万不要在虚拟机机中操作，不会成功的。因为目前不支持。

要想成功，需要在实体机中操作。

准备

确认版本

主要确认CUDA toolkit和nvidia的驱动版本。

经过实践之后，发现最靠谱的确定思路是:

首先根据本机的显卡版本，确定nvidia显卡的驱动版本，然后根据驱动版本确定CUDA toolkit的版本。

查看显卡的类型

可以看到显卡的类型为GeForce GTX 1060 3G

CUDA的core个数为: 1152个

确定显卡的驱动版本

https://www.geforce.com/drivers

然后可以查询到所有支持该显卡的驱动版本，最上边的为最新版本(除了beta版本)。

可看到当前nvidia显卡最新的驱动版本为: 390.87

确定CUDA toolkit的版本

CUDA toolkit对nvidia的版本有要求， 可参见https://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html中的CUDA Driver部分的说明:

linux平台下，由于nvidia driver的最新版本为390.87，所以无法选择CUDA 9.2, 因为它对driver的要求是>=396.26, 所以选择CUDA 9.1，它的要求是>=390.46, 满足要求。

查看系统和内核的要求

参见https://docs.nvidia.com/cuda/archive/9.1/cuda-installation-guide-linux/index.html中System Requirements部分的说明:

可见CUDA 9.1对各系统的要求。

比如CentOS 7.x，要求内核3.10， gcc版本4.8.5， GLIBC版本2.17等。

必要的查询

可参考https://docs.nvidia.com/cuda/archive/9.1/cuda-installation-guide-linux/index.html中的第2章。

(1) 查看是否存在支持CUDA的GPU

lspci | grep -i nvidia

可以在https://developer.nvidia.com/cuda-gpus查询本机的显卡是否支持CUDA。

(2) 查看当前linux版本是否支持

The CUDA Development Tools are only supported on some specific distributions of Linux.

$ uname -m && cat /etc/*release

You should see output similar to the following, modified for your particular system:

x86_64

Red Hat Enterprise Linux Workstation release 6.0 (Santiago)

The x86_64 line indicates you are running on a 64-bit system.

The remainder gives information about your distribution.

(3) 查看gcc的版本:

$ gcc --version

(4) 查看glibc版本

ll /lib64/libc.so.*

(5) 安装当前内核需要的kernel headers

这个步骤很重要。

sudo yum install "kernel-devel-uname-r == $(uname -r)"

安装显卡驱动和CUDA toolkit

Handle Conflicting Installation Methods中提到：

可见，同版本的显卡驱动和CUDA toolkit，如果再次安装时，需要卸载旧的版本。

如果CUDA toolkit已安装，可用如下途径卸载:

To uninstall the CUDA Toolkit, run the uninstall script in /usr/local/cuda-9.1/bin

To uninstall the NVIDIA Driver, run nvidia-uninstall

安装显卡driver

yum安装

大部分 Linux 发行版都使用开源的显卡驱动 nouveau，对于 nvidia 显卡来说，还是闭源的官方驱动的效果更好。

安装官方显卡驱动，可参考这个网址:https://blog.youkuaiyun.com/u013378306/article/details/69229919

里边介绍了一种简单的用yum安装nvidia显卡驱动的方法。

操作之前需要屏蔽默认带有的nouveau。

lsmod | grep nouveau

如果以上语句没有输出，则表示屏蔽默认带有的nouveau

成功。

这种方式，最后一步:

yum -y install kmod-nvidia

有时可能不成功，不过不妨碍使用

nvidia-detect -v

返回的结果去查找对应的驱动版本，进行安装。

源码安装

查找驱动的靠谱地址: https://www.geforce.com/drivers

安装过程可参考: https://blog.youkuaiyun.com/itaacy/article/details/72628792?utm_source=itdadao&utm_medium=referral

显卡安装成功后，可用如下命令查看显卡信息:

nvidia-smi

出现以上信息，说明显卡驱动安装成功。

卸载显卡驱动，可用如下指令:

nvidia-uninstall

安装 CUDA toolkit

注: 安装前应该关闭gnome。

获取CUDA toolkit下载地址:

CUDA toolkit 下载地址: https://developer.nvidia.com/cuda-toolkit-archive

下载CUDA 9.1。

安装CUDA:

sh cuda_9.1.85_387.26_linux.run

这种一般是nvidia显卡驱动的问题，需要安装最新的nvidia的驱动。

http://elrepo.org/tiki/tiki-index.php

rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org

rpm -Uvh https://www.elrepo.org/elrepo-release-7.0-3.el7.elrepo.noarch.rpm

然后按照https://blog.youkuaiyun.com/u013378306/article/details/69229919中用yum方式安装nvidia的驱动。

cudaGetDeviceCount returned 35

这种一般是cuda版本的问题。确定正确的版本，安装即可。

CUDA driver version is insufficient for CUDA runtime version就是说cuda runtime库的版本比driver的版本高了，要么装更高版本的驱动，要么就用低一点版本的cuda runtime库，所有的库都可以在这里面找到http://developer.download.nvidia.com/compute/cuda/repos/

Your kernel headers for kernel xxx cannot be found

图片发自简书App

The solution is likely to be found at this question the short version being, run

sudo yum install "kernel-devel-uname-r == $(uname -r)"

That will install the kernel headers for the version of the kernel you are currently running.
