Segmentation fault when importing osmium and torch

[SBCV]

Running

import torch
import osmium

causes

Process finished with exit code 139 (interrupted by signal 11: SIGSEGV)

I'm running Ubuntu 18.04 with miniconda.
pip list shows me that I'm using osmium 2.15.3 and torch 1.3.1.

This is likely a similar issue like #116 with incompatible libraries. Try installing pyosmium from source with: pip install --no-binary :all: osmium (you need to have the prerequisites installed as mentioned in the README).

https://uwekorn.com/2019/09/15/how-we-build-apache-arrows-manylinux-wheels.html describes the issue in detail and also the solution. It comes down to restricting the exported symbols.

Digging more into this: torch is heavily exporting all kinds of stuff from the stdlibc++, pyosmium doesn't export any symbols. So maybe the symbols are not the issue.

pybind/pybind11#1262 mentions that two modules using pybind11 might clash. For that issue an update to pybind11 2.4 would help. The latest release is still shipped with 2.3.

Fixed with manylinux2010 binary wheels. Please be aware that a recent version of pip is needed. The version shipped with Ubuntu is too old.
