When python applications look for the python library I often do it using:

python3
Python 3.6.1 (default, Mar 23 2017, 13:04:44) [GCC] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from distutils import sysconfig
>>> sysconfig.get_python_lib(standard_lib=True)
'/usr/lib/python3.6'
>>> sysconfig.get_config_var('LIBPL')
'/usr/lib64/python3.6/config-3.6m-x86_64-linux-gnu'
>>>

For this case there is a symlink in python2:

/usr/lib64/python2.7/config/libpython2.7.so -> ../../libpython2.7.so

This symlink doesn't exist for python3.

ll /usr/lib64/python3.6/config-3.6m-x86_64-linux-gnu

Please add the symlink to libpypthon3.6.so. Thanks!
