compile error: 'bpy::numeric' has not been declared

I am trying to build PyOpenPose on Ubuntu 16.04

~/work/PyOpenPose/build$ cmake ..

any ideas?

This looks like a boost-python version issue, can you try it with boost 1.58 (the default boost for ubuntu 16.04)?

[olimoser]

boost 1.58 is (also) installed
How can I force cmake/make to use this version?

[padeler]

Add the boost version in the find_package line in CMakeLists.txt, i.e. for python3 use:

find_package(Boost 1.58 EXACT COMPONENTS system python-py35 REQUIRED)  

[olimoser]

I still get the same error.
I installed boost 1.58 from source into a seperate folder.

my cmake command is:
cmake -DBOOST_ROOT=/home/user/work/boost_1.58/ -DBOOST_LIBRARYDIR=/home/user/work/boost_1.58/lib/ ..

cmake ..

Did you delete the cmake cache after the changes in the CMakeLists and rerun cmake?

[olimoser]

yes. I deleted the build folder including the cmake cache.

[padeler]

Did you find a solution for the issue? I was not able to reproduce it.

[christian-lanius]

I fixed the issue running with boost 1.66 as well. A dockerfile containing my build process can be found here. As far as I can tell PyOpenPose works with the latest master commit from openpose ( f6ade54)
I had the additional problem that the numpy headers were not added correctly by cmake. Because I wasn't sure if this problem is due to my setup, I haven't included the fix in the pull request. The fix can be seen in the commit 16695cc
