centos 安装cuda cudnn

#禁用nouveau

[root@localhost cuda] # sudo vim /etc/modprobe.d/blacklist.conf

blacklist nouveau
options nouveau modeset=0

[root@localhost cuda]# sudo dracut --force
[root@localhost cuda]# reboot
# 查询是否成功禁用nouveau 如果没有结果说明禁用成功
[root@localhost cuda]# lsmod |grep nouveau

#cuda下载地址 ：https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&Distribution=CentOS&target_version=7&target_type=rpm_local

# 查看NVIDIA驱动安装情况
[root@localhost cuda]# nvidia-smi```

## cudnn

自身采用的方式 下载完cudnn，tar解压包，然后将解压的文件include，lib64复制到/usr/local/cuda-（你的版本）/include/   usr/local/cuda-（你的版本）/lib64/


# 报错1
error：unable to find the kernel source tree for the currently running kernel. please make sure you have installed the kernel source files for your kernel and that htey are properly configured; on red hat linux system, for example, be sure you have the ‘kernel-source’ or ‘kernel-devel’ RPM installed. if you know the correct kernel source files are installed ,you may specify the kernel source path with the ‘–kernel-source-path’ command line option

```bash
# 查询版本号
[root@localhost cuda]# uname -r
# yum install -y kernel-devel(对应版本号) 
[root@localhost cuda]# yum install -y kernel-devel-3.10.0-1160.31.1.el7.x86_64
