ImportError: /usr/lib/libboost_python.so.1.66.0: undefined symbol: PyString_InternFromString

Hello,
I am using python3 as default. I am able to build setup.py successfully without any error, but while I try to execute ./bin/opensfm_run_all data/berlin I got this error:

Traceback (most recent call last):
File "/home/gary/project/OpenSfM/bin/opensfm", line 10, in

ImportError: /usr/lib/libboost_python.so.1.66.0: undefined symbol: PyString_InternFromString

Seems like it is using python2's boost instead of python3's. Is there any suggestion on how to fix this?

Start by reproducing ./bin/opensfm_run_all data/berlin, then inspect setup.py, opensfm/features.py, and the import of opensfm.csfm shown in the traceback. Determine why the built extension loads /usr/lib/libboost_python.so.1.66.0 with the wrong Python symbols; done means the command starts without the undefined-symbol ImportError.
