### win10安装cuda10.2和CUDNN ###

*  一、更新英伟达显卡驱动
 *  二、下载CUDA并安装
 *   *  开始安装cuda
 *  三、下载并安装cudnn

# 一、更新英伟达显卡驱动 #

打开英伟达控制面板——>系统信息——>组件：

查看是否支持CUDA10.2，大于支持，小于不支持，如果小于，则需要更新驱动，打开设备管理器  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L21hb19odWlfZmVp_size_16_color_FFFFFF_t_70 1]  
自动更新驱动即可。

# 二、下载CUDA并安装 #

下载地址：  
[https://developer.nvidia.com/cuda-toolkit-archive][https_developer.nvidia.com_cuda-toolkit-archive]

[windows版本cuda10.2下载地址][windows_cuda10.2]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L21hb19odWlfZmVp_size_16_color_FFFFFF_t_70 4]

## 开始安装cuda ##

★如果本机已经有了Visual Studio Integration文件，要取消勾选，避免冲突了。  
★如果本机没有的话，要勾选！！！  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L21hb19odWlfZmVp_size_16_color_FFFFFF_t_70 5]

如果本机的驱动版本(当前版本)小于cuda对应的版本（新版本），则选择，否则不选。如果当前版本小于新版本，并且不覆盖安装，之后电脑会频繁蓝屏或死机

记住安装路径：

等待一段时间，结束即可。  
安装两个补丁：选择自定义安装。

测试是否安装成功：

# 三、下载并安装cudnn #

下载地址：[CUDNN][]  
找到自己cuda对应的cudnn版本，下载  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L21hb19odWlfZmVp_size_16_color_FFFFFF_t_70 10]  
压缩包解压,下载后发现其实cudnn不是一个exe文件，而是一个压缩包，解压后，有三个文件夹，把三个文件夹拷贝到cuda的安装目录下，如果cuda安装的时候用的是默认路径，则为C:\\Program Files\\NVIDIA GPU Computing Toolkit\\CUDA\\v10.0，现在大家应该可以理解，cudnn其实就是cuda的一个补丁而已，专为深度学习运算进行优化的。

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L21hb19odWlfZmVp_size_16_color_FFFFFF_t_70 11]  
还记得我们前面安装的路径吗？，如果忘了，回去看一下。一般我们是默认安装在下面这个路径下的。

> C:\\Program Files\\NVIDIA GPU Computing Toolkit\\CUDA\\v10.2

当然后面那个v10.2是你自己的版本号。

找到这文件夹后，你需要把cuDNN里面的三个文件夹复制过来，不用担心，一起复制，没有重复文件，不会把里面的某些文件替换掉.

然后再参加环境变量，一般四个：

C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.2\bin
    C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.2\include
    C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.2\lib
    C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.2\libnvvp

测试是否安装成功，进入如下文件夹

> C:\\Program Files\\NVIDIA GPU Computing Toolkit\\CUDA\\v10.2\\extras\\demo\_suite>

运行下面命令

C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.2\extras\demo_suite>bandwidthTest.exe
