OpenCV / Cuda Version

[xiangdonglai]

Yes, we do use 2 version of OpenCV.

OpenCV 2.4.13 was compiled from source with CUDA 9.0, CUDNN 7.0. It is used in our C++ code.

OpenCV for python 3.5 was installed via pip3; the exact version is 3.4.2.17. This version is used in python code.
pip3 install opencv-contrib-python==3.4.2.17

I was using g++ 5.4.0 for all the C++ dependencies.

Unfortunately I don't remember the order of installation, but clearly OpenCV must be installed before OpenPose, Eigen3 must be installed before Ceres; other than these, the order does not seem to matter too much.

Thanks, this is really helpful!
Can you also let us know the version of gcc?
Did you use same gcc for compiling OpenCV, openpose, Ceres-Solver and libigl?

Also, in which order did you compile the dependencies? I don't think the order should matter, but it can give the hint of using wrong version of something to users in early stages.
In my case, with gcc-6 and CUDA 10.1, I could install everything but OpenCV 2.4.13.
And now I am installing from the beginning with CUDA 9.0 and CUDNN 7.5 (and trying different versions of gcc).

I cannot compile openpose current master with g++ 5.5.
However, it can be compiled with g++ 6.5. Could you please confirm your openpose version?

Never mind. I finally succeeded to run run_pipeline.sh with dependencies compiled with different g++!
