g2opy AttributeError: module 'g2o' has no attribute 'SparseOptimizer'

Installing with sudo (I was okay with that since I was using it in a container) seemed to work.

Naturally that would be in the system python. I don't quite understand the issue though? Do some modules under the Cmake file have permission requirements?

As discussed here, you need to build for the python version you're using. Remove the build folder and re-run cmake with:

cmake -DPYBIND11_PYTHON_VERSION=3.6 ..
make -j8

Note: don't run any export PYTHON_PATH=PATH-to-g2o/g2o:$PYTHONPATH because the g2o folder is in C++ and not what you want.
