Hey guys,

I installed mapnik from source and tried to install the python bindings as well. When I import mapnik I get an error. Can anyone help me?

I have a same problem

I discovered that is due to the inconsistency of the libboost-python libraries and the python version for which mapnik is building. In my case, docker container python:3.6-strech had python3.5 as system and, accordingly, libboost-python1.62 but build for python3.6. Therefore, mapnik needs to be built for python3.5 or update libboost-python to version 1.67. I was build mapnik in a debian:buster container and it's work fine. But you can don't build mapnik and just take from ppa. In buster system python is 3.7 and mapnik in ppa build for it.
