Installation of Openpose

Requirements:

Ubuntu 14/16
GPU 2GB/1.5GB (nvidia-smi view memory)
2GB RAM
8 core CPU

Very Important:
If you install the CUDA8 ubuntu14/16:
I. Needs: CUDA, CUDNN, OpenCV, Atlas
1.OpenCV:

sudo apt-get install Libopencv-dev

If OpenCV3 has been installed, modify the related makefile and change the corresponding line to: # Opencv_version: = 3
A opencv_contrib module is required. Installation method:

cmake-d cmake_build_type=release-d cmake_install_prefix=/usr/local-d Opencv_extra_modules_path=<path to Opencv_ Contrib/modules/>..

For example:

And then:

MAKE-J7
sudo make install

And in the makefile of libraries + = Opencv_core Opencv_highgui Opencv_imgproc finally plus Opencv_contrib
3.Atlas:

sudo apt-get install Libatlas-base-dev

You can also install Openblas or inter MKL and change blas: = Atlas to the appropriate.
two. Installation of Caffe and Openpose

chmod u+x install_caffe_and_openpose.sh
./install_caffe_and_openpose.sh

If you want to use CUDA7, install Caffe:

CD 3rdparty/caffe/# Select your desired file (run only one of the next 4 Makefile)  CP Makefile.config.Ubuntu14_cuda_7.example Makefile.config # Ubuntu, CUDA 7 CP Makefile.config.Ubuntu14.example
    Makefile.config # ubuntu, Cuda 8 cp Makefile.config.Ubuntu16_cuda_7.example Makefile.config # ubuntu, Cuda 7 CP Makefile.config.Ubuntu16.example Makefile.config # Ubuntu, 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} 

### Install openpose ###
    CD. /.. /models/
    ./getmodels.sh # It Just downloads the Caffe trained
    CD ...
    # Same file CP command as the one used for Caffe
    CP Makefile.config.Ubuntu14_cuda_7.example makefile.config
    # Chan GE any custom flag from the resulting makefile.config (e.g. OpenCV 3, ATLAS/OPENBLAS/MKL, etc.)
    Make All-j${number_of_cpus}

If you want to use your own caffe, install it according to the custom Caffe method.
If you need to modify something, please:

Make clean make
all-j$ (num_cores)

Tip:
There are altogether 2 makefile.config.ubuntu##.example, one of them in the ... In/3rdparty/caffe/, the configuration file in which the changes to two files are changed: OpenCV 3 flag, ATLAB/OPENBLAS/MKL flag, etc.
re-modified methods:

Make-Clean && CD-3rdparty/caffe && Make-clean

The

is then regenerated.

Solution:add "Opencv_imgcodecs" in Makefile. (Libraries + glog gflags protobuf leveldb snappy/lmdb boost_system hdf5_hl hdf5 m \ Opencv_core Opencv_highgui opencv_i Mgproc opencv_imgcodecs) If you input ' make all ', the problem is the same again. But If you delete all the file in Build (RM-RF./build/*) before ' Make all ' (I use ' make clean '), you'll success.

 For unfinished jobs .... Same solution by adding opencv_videoio into libraries in the Makefile

Similar problems, the solution is the same.
2. Opencv_contrib not found:
Replace it with some of the modules
