为了加快环境所需依赖的下载速度，首先更新 apt-get 源Ubuntu16.04[清华大学映像]

如何修改默认的更新源呢：

首先备份：$sudo cp /etc/apt/sources.list etc/apt/sources.list_backup

修改：$sudo gedit /etc/apt/sources.list

清空并替换为

# 默认注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security main restricted universe multiverse

# 预发布软件源，不建议启用
# deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-proposed main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-proposed main restricted universe multiverse

执行

$sudo apt-get update
$sudo apt-get upgrade
$sudo apt-get install python3-pip #安装pip

更新pip源

#在 ~/.config 下新建pip文件夹
#$cd ~/.config/pip
#$vim pip.conf

[global] 
index-url = https://pypi.tuna.tsinghua.edu.cn/simple 

保存退出

安装 numpy，是编译 tensorflow 和 opencv3 的依赖

$sudo pip3 install numpy

安装Nvidia驱动（也可在安装CUDA9同时安装驱动）

驱动版本查询Nvidia驱动程序

执行以下步骤

$sudo apt-get purge nvidia* #卸载所有显卡驱动 
$sudo add-apt-repository ppa:graphics-drivers/ppa #Personal Package Archives,也就是个人软件包集，添加驱动程序下载源
$sudo apt-get update && sudo apt-get install nvidia-384 nvidia-settings 

重启

$ nvidia-smi #输入命令，输出显卡信息及驱动程序版本

安装CUDA9

CUDA Toolkits download

选择CUDA9.0 ubuntu16.04 deb(local)

下载完成后执行

$sudo dpkg -i cuda-repo-ubuntu1604-9-0-local_9.0.176-1_amd64.deb
$sudo apt-key add /var/cuda-repo-<version>/7fa2af80.pub
$sudo apt-get update
$sudo apt-get install cuda

测试CUDA9.0

$nvcc -V #输出CUDA版本信息

测试Samples

$mkdir test
$cd test
$cp -r /usr/local/cuda-9.0/samples/ . 
$cd samples/ 
$make -j16
$cd ./1_Utilities/bandwidthTest
$./bandwidthTest 

查看最后结果，如果是Result = PASS，那就ok。

接着cd到根目录。编辑.bashrc文件

$sudo gedit .bashrc

在最后加上

#cuda9.0
export PATH=/usr/local/cuda/bin${PATH:+:${PATH}} 
export LD_LIBRARY_PATH=/usr/local/cuda/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}} 
export CUDA_HOME=/usr/local/cuda

保存退出。接着在命令窗口输入

$source .bashrc

让文件生效。

（请勿选择9.1，否则编译Tensorflow会出现问题）

如果误装了其他版本可通过以下方法卸载并重装

$sudo apt-get --purge remove cuda
$sudo apt autoremove
$sudo apt-get clean
$sudo dpkg -i cuda-repo-ubuntu1604-8-0-local-ga2_8.0.61-1_amd64.deb
$sudo apt-get update
$sudo apt-get install cuda-9-0

安装cudnn7

下载地址

注意自己的路径及cudnn版本

tar -zxvf cudnn-9.0-linux-x64-v7.tgz 
sudo cp cuda/include/cudnn.h /usr/local/cuda/include/ 
sudo cp -a cuda/lib64/libcudnn* /usr/local/cuda/lib64/ 
sudo chmod a+r /usr/local/cuda/include/cudnn.h 
sudo chmod a+r /usr/local/cuda/lib64/libcudnn*

注意上面第二条指令，这里多加了一个-a，在官方给的方案里面没有，我建议你这样做，否则会出现连接出错的问题。如果你忘记了，可以参考下面做法

#软链接至关重要
cd /usr/local/cuda/lib64/
sudo rm -rf libcudnn.so libcudnn.so.7.0  
sudo ln -s libcudnn.so.7.0.5 libcudnn.so.7.0  
sudo ln -s libcudnn.so.7.0 libcudnn.so 

安装Bazel

官方文档

配置Tensorflow1.4

获取源码

$git clone --recurse-submodules https://github.com/tensorflow/tensorflow
$cd tensorflow/

下面是我配置tensorflow的log,默认python3.5

Configuration finished

使用Bazel编译

bazel build --config=opt --config=cuda //tensorflow/tools/pip_package:build_pip_package

编译时间有点儿长。

bazel编译命令建立了一个名为build_pip_package的脚本。运行如下的命令将会在 /tmp/tensorflow_pkg路径下生成一个.whl文件。

$bazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/tensorflow_pkg

pip安装tensorflow

$sudo pip3 install /tmp/tensorflow_pkg/tensorflow-1.4.0-cp35-cp35m-linux_x86_64.whl

安装完毕 import tensorflow 进行验证。

安装opencv3.3

CUDA9.0只支持opencv3.3以上版本

1、下载opencv源码：https://github.com/opencv/opencv

2、下载 opencv_contrib 源程序https://github.com/opencv/opencv_contrib

下面开始安装

1、先将opencv和opencv_contrib解压到某个目录下，我的是在 /usr/opencv

2、依次执行下面的命令

$sudo apt-get update
$sudo apt-get upgrade

#opencv3.3的依赖
$sudo apt-get install build-essential cmake pkg-config
$sudo apt-get install libjpeg8-dev libtiff5-dev libjasper-dev libpng12-dev

$sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev

$sudo apt-get install libxvidcore-dev libx264-dev

$sudo apt-get install libgtk-3-dev

$sudo apt-get install libatlas-base-dev gfortran

$sudo apt-get install python3.5-dev python-numpy libtbb2 libtbb-dev  libdc1394-22-dev

进入opencv源代目录（如：/usr/opencv/opencv-master）,创建build目录

mkdir build
cd build

执行编译命令

sudo cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D PYTHON3_EXECUTABLE=/usr/bin/python3 -D PYTHON_INCLUDE_DIR=/usr/include/python3.5 -D PYTHON_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython3.5m.so -D PYTHON3_NUMPY_INCLUDE_DIRS=/usr/local/lib/python3.5/dist-packages/numpy/core/include -D INSTALL_PYTHON_EXAMPLES=ON -D INSTALL_C_EXAMPLES=OFF -D OPENCV_EXTRA_MODULES_PATH=/usr/opencv/opencv_contrib-master/modules -D PYTHON_EXECUTABLE=/usr/lib/python3 -D BUILD_EXAMPLES=ON ..

注意：在执行上面命令时，正常来说会到ippicv处时执行不下去，编译会退出，因为需要依赖 ippicv 的包编译时下载很慢，出现网络异常下载不下来。解决方法是建议先手动下载

ippicv_2017u2_lnx_intel64_20170828.tgz(github下载链接)

同时用该文件覆盖 /usr/opencv/opencv-master/ .cache(注意有“.”)目录下的 ippicv文件（文件名这里注意是一个很长的通过guid生成的名字，不能改变）。

如果编译通过当我没说 :）

$sudo make -j16
$sudo make clean
$sudo make install

$sudo ldconfig

如果没有问题的话就大功告成了。

配置完成之后，我们可以用搭建好的环境进行各种各样的视频Tracking.
