Import error

[mertmzk]

Hi @schroeder-dewitt

Thanks for your effort. I am trying to run your code without docker. I have compiled the orbslam.cpp using the build.sh file. It does not give any error while compiling but when I try to import it in python it gives following errors:
with python 2.7:

undefined symbol: _ZTIN5boost6python15instance_holderE

with python 3.5m

Segmentation fault (core dumped)

Has anyone got any solution for that?

Thanks in advance.

Hi Mertmzk,

Thanks a lot for your issue! I have just pushed an update to the Dockerfile which should allow you try the example as follows:

(Note: You require nvidia-docker plugin on host, as Pangolin2 requires OpenGL support)
sudo ./run.sh
(It will take a while to compile OpenCV3)
(SSH password: source)

Now, inside the container SSH shell, simply do:
(ensure build and bin folders are deleted to force CMake to update properly)
/orbslam/src/build.sh
export PYTHONPATH=/orbslam/src/build:$PYTHONPATH

Now you should be able to try the test example inside the container:
python3 /orbslam/src/test/test.py
(press key for GUI windows to open)

Let me know if the above recipe works! I have only tested python3, if you need python2.x support, then just let me know, should be easy to adapt.

All the best!

Having the exact same issue. Unable to get ORBSLAM2 importing properly outside of the container. I guess this was not intended in the repo anyway, but it would be good if this was also easy to do.
