血泪教训，openpose安装了一周，才安装成功，接下来说一下如何成功地安装编译openpose。
由于我是在服务器上这个应用，系统的CUDA和Cudnn都已经事先安装好了，所以我接下来的教程都是在cuda和cudnn已经安装成功的基础上进行的。
根据openpose的官方guthub上的安装指南 https://github.com/CMU-Perceptual-Computing-Lab/openpose/blob/master/doc/installation.md 需要安装opencv和caffe，这里就有一个问题了，我就是在这块被困住了。大部分人会先分别安装opencv和caffe然后再编译安装openpose，问题就在安装caffe的时候，我们可能会到caffe的官方github地址https://github.com/BVLC/caffe 下载源码安装，但是如果到这里下载编译安装caffe，在后期运行Openpose提供的例./build/examples/openpose/openpose.bin --video examples/media/video.avi 时，会报错，因此在编译安装caffe的时候，一定要下载指定的caffe版本，地址为 https://github.com/CMU-Perceptual-Computing-Lab/caffe/tree/b5ede488952e40861e84e51a9f9fd8fe2395cc8a
如果下载这个版本的caffe编译安装就不会出现问题了。
家下来分三个部分写安装过程：
（1）安装opencv
（2）编译caffe
（3）编译openpose
一.安装opencv:
最好是安装3.几的版本，不要安装4.0及以后的版本。 https://github.com/opencv/opencv/tree/master 注意选择
版本下载后进入安装过程：
（1）安装一些依赖文件：
sudo apt-get install build-essential
sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
（2）解压压缩包，进入opencv解压后的文件夹：
mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..
make -j7
sudo make install
至此opencv已经安装完成，写一个小代码检测是否成功：
#include<iostream>
#include<opencv2/opencv.hpp>
using namespace std;
using namespace cv;
int main()
{
Mat img = imread("me.png");
imshow("ME",img);
waitKey(0);
return 0;
}
这是一个显示图片的小图片，如果能够显示图片，则说明Opencv安装成功。这个小程序文件名称为test.cpp 。编译语法为
g++ -std=c++11 test.cpp -o test `pkg-config --cflags --libs opencv`
编译后生成 test 文件，运行这个可执行文件 ./test
显示结果如图所示：
二.编译CAFFE
下载完成openpose指定的caffe源码后，解压这个压缩包，然后进入源码文件夹
新建一个文件 makefile.config 打开这个文件，将下面的代码复制粘贴进这个新建的文件，然后保存

Q ?= @这和文件里面涉及到CUDA和CUDNN是否使用的选择，因为我要使用这两个东西，所以都设置为使用，注意这里面的
CUDA_DIR := /usr/local/cuda-9.0
路径要设置为自己的CUDA路径，前缀/usr/local 应该都一样，就看看自己的CUDA版本是否一样，根据自己的进行改进就行。
然后运行
make all
make test
make runtset
在编译的过程中，如果出现 fatal error: ****.h: No such file or directory 的错误指令，那么就说明编译指令没找到****.h这个头文件，那么我们打开一个终端，运行 locate ****.h 查看这个文件在什么位置，然后到makefile.config 中找到INCLUDE_DIRS := 这个字段，将对应的目录加入到后面。
三.编译openpose
先进入openpose源码的文件夹，然后建立build文件夹：
make build
cd build
cmake -D CUDA_TOOLKIT_ROOT=/usr/local/cuda-9.0 -D BUILD_CAFFE=OFF -D Caffe_INCLUDE_DIRS=/home/tcr/test_caffe/caffe/include -D Caffe_LIBS=/home/tcr/test_caffe/caffe/build/lib/libcaffe.so ..
make -j `nproc`
