I get the same error. Any solution on that?

I am afraid that link is g2o written in C++, does that work well with my project written in python?

[ptrem]

As described in: miquelmassot/g2o-python#40

I used this repo: https://github.com/miquelmassot/g2o-python
and the pymem branch from https://github.com/RainerKuemmerle/g2o.git.
Worked for me. I also use it inside my Python Project.
