cannot import g2o in my intepretor

[shaoxh]

I have finish the final installation: "python setup.py install".
The .so file have been added to the packages.
But when I import g2o, there is error like this: "malloc(): memory corruption".
When I debug an example called ba_demo.py, error message like this:
Traceback (most recent call last):
File "", line 971, in _find_and_load
File "", line 955, in _find_and_load_unlocked
File "", line 658, in _load_unlocked
File "", line 571, in module_from_spec
File "", line 922, in create_module
File "", line 219, in _call_with_frames_removed
ImportError: /usr/lib/python3/dist-packages/g2o.cpython-36m-x86_64-linux-gnu.so: undefined symbol: cs_di_schol
python-BaseException

But the thing is ".so" file have been sucessfully achieved. All is right.
I have no idea where this error come from.

I realize nobody ask this kind question. Is this because this project no longer fit to the current g2o codes?
