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?

In executable scripts, we are using the shebang #!/usr/bin/env python. This is calling python2 in most systems.

As of now, the simplest solution to run using python3 is to call the opensfm using as

python3 opensfm command path/to/dataset

You can edit the opensfm_run_all script to do so as

#!/usr/bin/env bash

set -e

DIR=$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )
