openpose: how to install

1. how to build openpose

cmake -DOpenCV_INCLUDE_DIRS=/usr/local/include \
  -DOpenCV_LIBS_DIR=/usr/local/lib \
  -DCaffe_INCLUDE_DIRS=/home/"${USER}"/workspace/caffe3/distribute/include \
  -DCaffe_LIBS=/home/"${USER}"/workspace/caffe3/build/lib/libcaffe.so -DBUILD_CAFFE=OFF ..

cmake -Dpython_version=3 -DBUILD_PYTHON=1 -DCMAKE_INSTALL_PREFIX=/home/ninja/workspace/openpose/build/install ..

make all -j32

sudo make install

export PYTHONPATH=/home/ninja/workspace/openpose/build/install/python

2. how to run testing

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

CUDA_VISIBLE_DEVICES=0 ./build/examples/openpose/openpose.bin --net_resolution "160x80" --video examples/media/video.avi

3. how to use python library

ninja@pp-pc:~/workspace/openpose$ python build/examples/tutorial_api_python/01_body_from_image.py

(an output image will be shown)


4. how to use docker (failed)

docker run -it --rm --runtime=nvidia -e NVIDIA_VISIBLE_DEVICES=0 cwaffles/openpose-python

apt-get install xauth


docker run -it --rm --runtime=nvidia -e NVIDIA_VISIBLE_DEVICES=0 openpose:docker

modules/python_bindings_generator/pyopencv_generated_include.h' failed

1. cd to workspace/opencv

2.  then type,

python ./modules/python/src2/gen2.py ./build/modules/python_bindings_generator ./build/modules/python_bindings_generator/headers.txt

3.after that, continue as usual cmake and make 

/usr/lib/x86_64-linux-gnu/libunwind.so.8: undefined reference to `lzma_index_end@XZ_5.0'

may be python version is wrong, try

cmake -Dpython_version=3 ..

how to mount the host folder into docker folder

 docker run -it --rm --runtime=nvidia -e NVIDIA_VISIBLE_DEVICES=0 -v /home/ninja/tmp/:/openpose/tmp openpose:docker

-v host_folder:docker_folder

How to check the current cudnn?

dpkg -l | grep cudnn
