how to install and configure libboost and dlib for python 3.6 on CentOS 7

  • 772

I have this setup

  • CentOS 7 64bit
  • Python 2.7 and 3.6
  • pip and pip3.6
  • dlib 19.3
  • libboost 1.53

I've dlib 19.3.0 libboost 1.53 working properly with python 2.7

Now I need to run dlib and libboost with python 3. I tried several things but no luck. I get this error when i try to import dlib in python 3

import dlib
  File "/usr/lib64/python3.6/site-packages/dlib/__init__.py", line 1, in <module>
    from .dlib import *
ImportError: libboost_python3.so.1.64.0: cannot open shared object file: No such file or directory

Reason it says libboost_python3.so.1.64.0 because i tried many things to make it work even trying to build dlib and libboost from source (which i've no idea what i was doing) but no luck.

I really appreciate any help you can provide to make dlib and libboost work with python 3.

  1. Dlib is not looking in the correct location for Boost. There is a workaround for this by using an environment variable (LD_LIBRARY_PATH) to tell Python how to find the libboost SO. Assuming your libboost SO has been dropped in /usr/local/lib,

    export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
