環境和上一篇安裝caffe是一樣的，安裝openpose的難點主要是caffe的安裝。。
正文。。。
依賴： Ubuntu20.04 cuda10.1 cudnn7.6.0 OpenCV4.5.1 Python 3.8+Numpy
1. 下載源碼及模型
這一步下載速度可能很慢，除非你能xx，原因你們懂得。。。也可以百度一下提前下載好模型放到對應的位置
git clone https://github.com/CMU-Perceptual-Computing-Lab/openpose.git
cd openpose
cd models
./getModels.sh
cd ..
2. 下載第三方庫
因為里面的兩個第三方庫是空的
cd 3rdparty/ git clone https://github.com/CMU-Perceptual-Computing-Lab/caffe.git git clone https://github.com/pybind/pybind11.git
3. 手動編譯caffe
這里的安裝步驟和上一篇安裝caffe是一樣的，所以移步參考這一篇文章：
ubuntu20.04+cuda10.1+cudnn7.6.0+opencv4.5.1+python3.8安裝caffe
只不過在復制Makefile.config的時候更改一下
cp Makefile.config.Ubuntu16_cuda8.example Makefile.config
編譯成功后，會生成 caffe/build/lib/libcaffe.so 文件
4. cmake
打開cmake-gui界面
cmake-gui
點擊configure，然后默認選擇點擊finish
Unix Makefiles
Use default native compilers
然后更改成這樣
再點擊configure，然后再點擊generate
5. 編譯openpose
在openpose根目錄下
cd build make -j8
如果編譯過程中出現過一個錯誤 cannot find #include “caffe/proto/caffe.pb.h”
# 在caffe根目錄 protoc src/caffe/proto/caffe.proto --cpp_out=. mkdir include/caffe/proto mv src/caffe/proto/caffe.pb.h include/caffe/proto
然后在build目錄下重新編譯
make clean make -j8
6. 測試
在根目錄下
./build/examples/openpose/openpose.bin --video examples/media/video.avi
2021.4.5補充
由於python比較方便，補充了python接口
caffe編譯過程不變，只是在上面打開 cmake-gui 之后的過程有改動
由於cmake-gui 找到的python路徑有問題，一直沒能解決，因此使用cmake指定python路徑
按照正常流程編譯完openpose-caffe模塊后
在openpose根目錄下
mkdir build_py && cd build_py cmake -DCUDNN_LIBRARY=/usr/local/cuda/lib64/libcudnn.so \ -DBUILD_PYTHON=ON \ -DBUILD_CAFFE=OFF \ -DCaffe_INCLUDE_DIRS=/home/lhw/Gradute/collage/openpose/3rdparty/caffe/include \ -DCaffe_LIBS=/home/lhw/Gradute/collage/openpose/3rdparty/caffe/build_syspy/lib/libcaffe.so \ -DPYTHON_LIBRARY=/usr/lib/python3.8/config-3.8-x86_64-linux-gnu/libpython3.8.so \ -DPYTHON_INCLUDE_DIRS=/usr/include/python3.8 \ -DPYTHON_DEFAULT_EXECUTABLE=/usr/bin/python3 ..
-DPYTHON_LIBRARY 與 -DPYTHON_INCLUDE_DIRS一定要版本對應，否則后面會出現動態鏈接庫不對應的問題

無誤后編譯openpose
make -j8
sudo make install
無誤后測試python模塊，此時在build_py文件夾下
cd examples/tutorial_api_python/ python 01_body_from_image.py
# 或者在openpose根目錄下，測試python api
python /pybuild/examples/tutorial_api_python/python 01_body_from_image.py
#測試c++ api模塊
./pybuild/examples/tutorial_api_cpp/01_body_from_image_default.bin
