ubuntu 18.04 安装CUDA + CUDNN + tensorflow-gpu_ubuntu18.04安装tensfrflow-gpu

预备条件: 安装2080Ti的驱动

直接参考这个Ubuntu 18.04安装NVIDIA（英伟达） RTX2080Ti显卡。但是请注意，里边有个地方命令中包含了中文，

#原文中这里的-no-opengl-files -no-x-check的 - 是中文的，我这边改成了英文，其他的没啥错误
sudo bash NVIDIA-Linux-x86_64-430.26.run -no-opengl-files -no-x-check

一. 查看tensorflow-gpu对应的python，CUDA以及CUDNN的版本

通过tensorflow-gpu配置，得到如下信息:

这里本人打算安装tensorflow-gpu 2.3版本的，所以采用的CUDA版本为10.1,CUDNN版本为7.6。

二. 安装CUDA

首先去官网地址

因为我们想要下载的CUDA的版本是10.1，截止目前2021/12/22最新版本是11.5。所以需要下载历史版本。你可以点击图中的历史版本的链接，也可以点击此链接去下载:

接着点击左侧的CUDA Toolkit 10.1 update2

按照上面的点击顺序可以得到下面这个图片:

图片中的文字就是安装步骤:

$ wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/cuda-ubuntu1804.pin
$ sudo mv cuda-ubuntu1804.pin /etc/apt/preferences.d/cuda-repository-pin-600
$ wget https://developer.download.nvidia.com/compute/cuda/10.1/Prod/local_installers/cuda-repo-ubuntu1804-10-1-local-10.1.243-418.87.00_1.0-1_amd64.deb
$ sudo dpkg -i cuda-repo-ubuntu1804-10-1-local-10.1.243-418.87.00_1.0-1_amd64.deb
$ sudo apt-key add /var/cuda-repo-10-1-local-10.1.243-418.87.00/7fa2af80.pub
$ sudo apt-get update
$ sudo apt-get -y install cuda

你如果想要安装不同于10.1版本的CUDA的话，你就按照上面图片点击后产生的安装步骤来（不要局限于我这个版本的）。

2.1 如何判断CUDA是否成功安装成功

这里介绍两种方式:

方法1:
$ cd /usr/local
$ ls #你会发现出现了cuda-10.1,切记因为我安装的是10.1版本的，所以你ls以后不一定是cuda-10.1
bin   cuda-10.1  etc    go       lib  sbin   src
cuda  doc        games  include  man  share  sunlogin
$ cd cuda-10.1
$ ls 
bin     include    libnvvp           nvml    samples  targets
doc     lib64      LICENSE           nvvm    share    tools
extras  libnsight  nsightee_plugins  README  src      version.txt
$ cat version.txt #这里就表示你安装成功了
CUDA Version 10.1.243

方法2: #还是在这个目录下
$ cd bin 
$ ./nvcc -V #出现下面这个也表示成功了
nvcc: NVIDIA (R) Cuda compiler driver

这样就表示我们安装成功了，当然可能见过如下测试方式:
$ nvcc -V
其实这个方法就是方法二，为啥我们这里不直接使用nvcc -V呢？因为，我们没有把nvcc进行环境配置，就是在别的目录下不能识别到这个可执行文件。下面是这个nvcc的环境变量配置:

$ sudo vim ~/.bashrc
#在末尾加上这两句话
export PATH=/usr/local/cuda-10.1/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-10.1/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
$ #保存并退出
$ source ~/.bashrc #使配置文件生效
#接着打开/etc/profile
$ sudo vim ~/.profile
#在末尾加上这两句话
PATH=/usr/local/cuda/bin:$PATH
export PATH
$ source ~/.profile #使之生效

$ nvcc -V #配置成功

三. 安装CUDNN

依然是打开CUDNN官网

选择Archived cuDNN Release去下载CUDNN历史版本。因为前面说了我们想要下载的tensorflow-gpu 2.3对应的CUDNN版本为7.6

我选择的是用deb方式安装的

3.1安装CUDNN

$  sudo dpkg -i libcudnn7_7.6.5.32-1+cuda10.1_amd64.deb

3.2 测试安装是否成功

$ cd $HOME/cudnn_samples_v7/mnistCUDNN

四安装 tensorflow-gpu

#首先安装python3,如果你ubuntu18.04 自带python3，就不用安装了（大部分都自动python3.6.9
$ sudo apt-get install python3
#首先安装pip3
$ sudo apt-get install python3-pip
#接着升级下你的pip3
$ pip3 install --upgrade pip
#换下pip的源
$ sudo mkdir ~/.pip
$ cd ~/.pip
$ sudo vim pip.conf  #把下面的内容加上
[global]
index-url = http://mirrors.aliyun.com/pypi/simple
[install]
trusted-host=mirrors.aliyun.com
#最后安装tensorflow-gpu
$ pip3 install tensorflow-gpu==2.3.2
#注意，虽然出现了这个错误，但是没有影响我最后的使用
