1.  一个失败的尝试

首先是跑一个例子试试，使用

https://github.com/CMU-Perceptual-Computing-Lab/openpose/

按照作者的指导，如下：

Training Steps

  • Run cd training; bash getData.sh to obtain the COCO images in dataset/COCO/images/, keypoints annotations in dataset/COCO/annotations/ and COCO official toolbox in dataset/COCO/coco/.
    • 　　这里建议开screen，因为要下载超级久
  • Run getANNO.m in matlab to convert the annotation format from json to mat in dataset/COCO/mat/.
  • Run genCOCOMask.m in matlab to obatin the mask images for unlabeled person. You can use 'parfor' in matlab to speed up the code.
    • 　　注意修改Matlab程序中的路径，在  im = imread(['dataset/COCO/', img_paths]);的COCO后面加上images/，原程序有点问题
    • 这里尝试开启了一下并行运算，速度特别快，将代码中第二个for循环改为parfor i = 1:L，然后使用Matlab的时候，先输入matlabpool open，然后再运行程序。关闭的方法为matlabpool close
      • 　　然后遇到了Subscripted assignment between dissimilar structures.问题，看代码也没有找到问题，参考 [1]
  • Run genJSON('COCO') to generate a json file in dataset/COCO/json/ folder. The json files contain raw informations needed for training.
  • Run python genLMDB.py to generate your LMDB. (You can also download our LMDB for the COCO dataset (189GB file) by: bash get_lmdb.sh)
  • Download our modified caffe: caffe_train. Compile pycaffe. It will be merged with caffe_rtpose (for testing) soon.
  • Run python setLayers.py --exp 1 to generate the prototxt and shell file for training.
  • Download VGG-19 model, we use it to initialize the first 10 layers for training.
  • Run bash train_pose.sh 0,1 (generated by setLayers.py) to start the training with two gpus.

2. 安装Caffe

这种跑一个例子失败之后，

转而使用最根本的方法从头按照步骤编译，不走捷径：参考下面的网址

因为电脑里已经安装过caffe的依赖环境了，所以把caffe编译一下就可以用了，参考下面的话 [3]

### Install Caffe ###

cd 3rdparty/caffe/

# Select your desired Makefile file (run only one of the next 4 commands)

cp Makefile.config.Ubuntu14_cuda7.example Makefile.config # Ubuntu 14, cuda 7

cp Makefile.config.Ubuntu14_cuda8.example Makefile.config # Ubuntu 14, cuda 8

cp Makefile.config.Ubuntu16_cuda7.example Makefile.config # Ubuntu 16, cuda 7

cp Makefile.config.Ubuntu16_cuda8.example Makefile.config # Ubuntu 16, cuda 8

# Change any custom flag from the resulting Makefile.config (e.g. OpenCV 3, Atlas/OpenBLAS/MKL, etc.)

# Compile Caffe
make all -j${number_of_cpus} && make distribute -j${number_of_cpus}

比如make all -j16（使用16个CPU同时运行）

                           3. 安装 OpenPose

cd ../../models/

bash ./getModels.sh # It just downloads the Caffe trained models

cd ..

# Same file cp command as the one used for Caffe

cp ubuntu/Makefile.config.Ubuntu14_cuda7.example Makefile.config

# Change any custom flag from the resulting Makefile.config (e.g. OpenCV 3, Atlas/OpenBLAS/MKL, etc.)

make all -j${number_of_cpus}

一定要严格按照顺序（实验室服务器用的是zsh，所以注意替换bash为zsh）

如果使用OpenCV 3版本的话，可以通过所有make，但是不能运行实际的例子

按照作者在某个Issue下的回答，应该使用OpenCV2.4，然后折腾很久，见另一篇博客 [7]

然后出现无法make，错误中关键行为这个

../lib/libcaffe.so: undefined reference to cv::imread(cv::String const&, int)'

搜索之后得到解答：[4]

open your Makefile with some text editor, locate line 164 (in my case), add opencv_imgcodecs behind.

 LIBRARIES += glog gflags protobuf leveldb snappy \

  lmdb boost_system hdf5_hl hdf5 m \

  opencv_core opencv_highgui opencv_imgproc opencv_imgcodecs

在vim里使用

:se nu

然后回车，可以显示行号；使用

/opencv

可以快速定位到第一个出现的opencv字符串的位置

添加后可以make了，然后不出意料的还是不能运行实际的例子：

4. 运行一个例子

实际例子运行方法：[3]

1. Running on Video

# Ubuntu

./build/examples/openpose/openpose.bin --video examples/media/video.avi

# With face and hands

./build/examples/openpose/openpose.bin --video examples/media/video.avi --face --hand

会出现

zsh: abort (core dumped)  ./build/examples/openpose/openpose.bin --video examples/media/video.avi

再试试别的运行方法：

3. Running on Images

# Ubuntu

./build/examples/openpose/openpose.bin --image_dir examples/media/

# With face and hands

./build/examples/openpose/openpose.bin --image_dir examples/media/ --face --hand

会出现

Starting pose estimation demo.

Error:

Coming from:

- src/openpose/utilities/fileSystem.cpp:getFilesOnDirectory():186

- src/openpose/producer/imageDirectoryReader.cpp:getImagePathsOnDirectory():25

- src/openpose/utilities/flagsToOpenPose.cpp:flagsToProducer():133

terminate called after throwing an instance of 'std::runtime_error'

what():

zsh: abort (core dumped)  ./build/examples/openpose/openpose.bin --image_dir examples/media/

然后搜索后，根据 [5] DuinoDu的回答，去 [6] 里找答案，“install boost from src.”

根据user3715812的回答，输入以下命令行来安装BOOST：

wget -O boost_1_55_0.tar.gz http://sourceforge.net/projects/boost/files/boost/1.55.0/boost_1_55_0.tar.gz/download

tar xzvf boost_1_55_0.tar.gz

cd boost_1_55_0/

./bootstrap.sh --prefix=/usr/local     // 这里改成自己想要安装到的目录

./b2

./b2 install       // 没有SUDO权限但是也可以

然后再去运行

./build/examples/openpose/openpose.bin --image_dir examples/media/

这次的报错和上次不一样了，是

Starting pose estimation demo.

zsh: abort (core dumped)  ./build/examples/openpose/openpose.bin --image_dir examples/media/

然后在GITHUB 的ISSUE区准备提问的时候，根据提示

Note: add --logging_level 0 to get higher debug information.

在运行的命令行后加上了这个，即：

./build/examples/openpose/openpose.bin --image_dir examples/media/  --logging_level

于是得到了较为准确的信息：

姿势估计实验-Realtime_Multi-Person_Pose_Estimation-CMU

可以理解为又一个图形界面要展示但是出不来 [8]（X server相关),

查阅资料后根据 [9] 的xiaoyan的回答：

Add "export DISPLAY=your ip:0.0" in ~/.bashrc, source ~/.bashrc (ip is your host IP, where you wanna display plots or things like that. If you are using Windows, cmd-ipconfig, find your IP).

于是不再出现X server问题了，出现了下图的问题

姿势估计实验-Realtime_Multi-Person_Pose_Estimation-CMU

找了好久没找到问题，最后求助了组里的史博士，这里表示非常感谢！！！

原因是这个Demo默认使用所有探测到的CUDA 设备，而实验室的CUDA设备还有很多人在用，这会造成问题（可能是冲突或者资源不够，或者不被允许个人使用这么多个？）

所以在运行的命令行前面要加上一定的限制：

CUDA_VISIBLE_DEVICES= ./build/examples/openpose/openpose.bin --net_resolution "160x80" --video examples/media/video.avi

使得被探测到的设备数量只有两个。

然后发现还是运行不了，为什么呢？

因为OS X上的SHELL并不具备显示远程窗口的功能，

所以在史博士的推荐下使用了MobaXterm（在WIN10下），然后就成功了，因为这个软件直接内置了X server的接口

更新：如果想在Mac上运行，可以参考

[10] http://blog.csdn.net/dobell/article/details/55047811

安装XQuartz，
https://www.xquartz.org

按说明安装好

打开 mac terminal

ssh -X   {用户名}@{远程端ip}； （注意大写的X）

这次就可以了

实际运行截图如下：

姿势估计实验-Realtime_Multi-Person_Pose_Estimation-CMU

 

你也可以读一下我在GITHUB上的提问：
https://github.com/CMU-Perceptual-Computing-Lab/openpose/issues/184可能会有帮助

另外：

因为实验室的服务器出于安全考虑不允许使用

sudo pip install

, 所以使用

pip install --user

来替代。[2]
