An error when I compile DRL_graph_exploration

when I do the final step make, it occurs an error:

I don't know how to solve it

It looks like pybind11 has a problem with Point2 Class. Have you installed the newest GTSAM via their official website? If you installed the one from their website, please delete it:

sudo rm -r /usr/local/lib/libgtsam* /usr/local/include/gtsam*

, and use the link we provided to install GTSAM:

git clone -b emex --single-branch https://bitbucket.com/jinkunw/gtsam
cd gtsam
mkdir build && cd build
cmake ..
sudo make install

In the newer GTSAM version, there is no Point2 Class so pybind11 has the problem to convert Point2. If you have the correct dependencies, you will see these lines at the beginning to indicate that the configuration is correct:

-- GTSAM include directory:  /usr/local/lib/cmake/GTSAM/../../../include;/usr/include;/usr/local/include/gtsam/3rdparty/Eigen/
-- Found pybind11: /usr/local/include (found version "2.6.3" dev1)
-- Configuring done

First of all, thank you for your reply. I will try your method
But what puzzles me most is that it's not the first time that I report an error in the ss2d.cpp file. Why doesn't point2 report an error in the first place
