前言

使用CUDA开发AI项目必然离不开CUDA和CUDNN的安装，今天这篇文章就是教你怎么验证CUDA和CUDNN是否安装成功和验证版本是不是安装对了。

一、安装

怎么安装CUDA和CUDNN这里就不多说了，随便都能搜到。简而言之就是显卡驱动->CUDA->CUDNN这种安装顺序。其中，显卡驱动又可以通过普通安装、CUDA附带安装和DKMS安装，这几种方式。具体的请自行查阅其它博主文章。

二、关键指标

显卡驱动和CUDA版本有对应关系，CUDA版本和CUDNN版本又有对应关系，这里简单通过CUDA-11.2来说明这种关系，从而防止小白踩坑。请认真往下看：

1.驱动版本和CUDA版本对应

CUDA-11.2官网说明

进去之后点击Release Notes标签，之后往下看找到驱动项。

1.最适配版本

仔细看，主要是Windows和Linux。其中，Windows就不说了，Windows10或Windows11。Linux包括我们常用的Ubuntu、Debian、CentOS等等。这里，我们只讨论Ubuntu，因为其它系统我没装，理论上是一样的，你只需要在操作系统选择里选择对应的下载就行了。

这里只做下演示，按照你的操作系统版本选就行了，没什么难度，等待下载好安装。

回到刚才的驱动版本，CUDA-11.2版本对Linux驱动要求是>=460.27.04；Windows是>=460.89。这个驱动是版本最匹配的版本，当然只要大于这个版本都行。有时候，你可能还会遇到比较特殊的一种版本要求。请继续往下看：

2.最低支持版本

以CUDA-11.8版本为例，这个CUDA版本官方标注了最低版本驱动要求，
CUDA-11.8官网说明

同样，进去之后点击Release Notes标签，之后往下看找到驱动项。

如何判断是否安装hbase 如何判断是否安装cuda_deep learning_03

从图片中看到从CUDA-11.0到CUDA-11.8家族都是支持这种最小化驱动需求的。这意味着我们的程序可以跑起来，但是难道这意味着Minimum和Compatiable没有区别吗？答案当然是非也，请看官方说明：

From CUDA 11 onwards, applications compiled with a CUDA Toolkit release from within a CUDA major release family can run, with limited feature-set, on systems having at least the minimum required driver version as indicated below. This minimum required driver can be different from the driver packaged with the CUDA Toolkit but should belong to the same major release.

看不懂没关系，关键在这一句：with limited feature-set。简而言之，核心功能能用，一些新特性可能不能用，简单来说，尽量安装Compatiable版本的驱动，Minimum是无奈之举。当然，驱动怎么升级这里就不说了，可以自行检索。

总结，驱动向下兼容，尽量安装高版本。

2.CUDA版本和CUDNN版本对应

一般来说，每个CUDA版本都至少有一个版本的CUDNN和它对应。注意：是至少一个版本，可以是多个版本。以CUDA-11.2为例，我们看下官网：

如何判断是否安装hbase 如何判断是否安装cuda_ubuntu_04

图片有点长，我们简略看一下。从8.1.0版本开始，CUDNN开始支持CUDA-11.2。简而言之，如果你安装了CUDA-11.2，CUDNN至少安装8.1.0，当然可以根据需要安装后续的支持版本，包括11.x。还是建议如果不是特殊需求，尽量不要过度追求高版本，可能带不来实质性的性能提升。

好了，对应版本介绍完了，下面说下验证安装的问题。

三、验证有效性

显卡驱动+CUDA+CUDNN三者缺一不可。验证方法也不是只有一种，我介绍几种给你做参考。

1.驱动验证

如果正常显示出来，而且检测出显卡就说明驱动没问题。

说下几个主要指标：

NVIDIA-SMI 460.27.04：工具版本
Driver Version: 460.27.04：显卡驱动版本
CUDA Version: 11.2：参考CUDA版本，具体以官网为准 GPU：显卡序号，0是第一块显卡，以此类推，可以混插不同型号（少见），具体以实际为准
Name：显卡名字，Geforce RTX 2080 Ti ，类似这种
Fan：风扇转速比例，如果核心温度上升风扇会转的更快
Temp：显卡核心温度（摄氏度），温度过高会降频，从而引发显卡效率下降
Pwr：当前功耗/热设计功耗，一般不会超过功耗墙，除非手动调整
Memory-Usage：显存占用/显存总量，爆显存会严重影响效率，或者导致任务被kill
GPU-Util：显卡性能占用百分比，如果是100%意味着显卡性能吃满了
Processes：目前正在使用显卡的应用程序，包括AI和编解码

2.CUDA验证

这个比较简单，最常用的方法就是nvcc

1.nvcc

nvcc -V
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2020 NVIDIA Corporation
Built on Mon_Nov_30_19:08:53_PST_2020
Cuda compilation tools, release 11.2, V11.2.67
Build cuda_11.2.r11.2/compiler.29373293_0

只要可以打印，而且版本是对的就行了。

2.sample

这个方法要复杂点，一般不用。需要安装CUDA的时候勾选CUDA Sample。

只要编译源代码，然后执行示例程序，没报错就是可以的。方法虽然复杂了点，但是比nvcc更靠谱，专业！

3.CUDNN验证

由于CUDNN是个纯的库，默认的CUDNN没有什么BIN文件，所以验证起来也不如CUDA那么容易。当然，并不意味着没办法，方法也有两种：

1.头文件验证法

可能的安装路径是/usr/include/cudnn.h或/usr/local/include/cudnn.h

whereis cudnn_version.h
cudnn: /usr/include/cudnn_version.h

我的在这个目录下，接下来通过连续命令来确认CUDNN版本。

cat /usr/include/cudnn_version.h | grep -A 5 MAJOR
#define CUDNN_MAJOR 8
#define CUDNN_MINOR 1
#define CUDNN_PATCHLEVEL 0

#define CUDNN_VERSION (CUDNN_MAJOR * 1000 + CUDNN_MINOR * 100 + CUDNN_PATCHLEVEL)

#endif /* CUDNN_VERSION_H */

grep -A 5是查到MAJOR字段后再往下展示5行。可以看到CUDNN版本有3个部分组成，组合起来就是8.1.0。

注意，这个方法其实是有漏洞的，它只能说明你这个目录下有CUDNN文件，并不能说明CUDNN就一定安装成功了。如果非要抬杠的话，如果库被误删了呢？还能说明CUDNN是完整的吗？

当然，绝大多数情况下只要CUDNN正常安装就没有问题。

2.sample验证法

前提是，你安装了CUDNN的sample，请看下图：

如何判断是否安装hbase 如何判断是否安装cuda_ubuntu_05

8.1.0版本CUDNN包有三个部分组成，其中Runtime是必须的，Dev是开发环境，Smaple是示例代码，建议3个都装，一步到位。请看下面操作：

cd /usr/src/
ls
cudnn_samples_v8

要么在/usr/src/下，要么在/usr/local/src下。我们接着操作：

cd cudnn_samples_v8/
cd mnistCUDNN/
./mnistCUDNN
Executing: mnistCUDNN
cudnnGetVersion() : 8100 , CUDNN_VERSION from cudnn.h : 8005 (8.0.5)
Host compiler version : GCC 7.5.0

Result of classification: 1 3 5

Test passed!

重点是：cudnnGetVersion() : 8100，这个就是程序检测到的CUDNN版本，以这个为准。
最后：Test passed!，出现这个说明成功了，包括驱动+CUDA+CUDNN全部成功了。如果失败了，你需要再检查下安装环境了！

总结

1、方法还有很多，两个就够了
2、如果环境有问题，大概率测试程序是跑不完的
