Ubuntu16.04 can NOT run Two-lane highway test

Hi, Thanks for the great work

I try to run the single_2lanefree_carla on Ubuntu 16.04, but it failed:

---

~/OpenCDA$ python opencda.py -t single_2lanefree_carla OpenCDA Version: 0.1.0 Traceback (most recent call last): File "opencda.py", line 56, in main() File "opencda.py", line 40, in main testing_scenario = importlib.import_module("opencda.scenario_testing.%s" % opt.test_scenario) ... import open3d as o3d File "/home/anaconda3/envs/opencda/lib/python3.7/site-packages/open3d/init.py", line 56, in _CDLL(str(next((_Path(file).parent / 'cpu').glob('pybind*')))) File "/home/anaconda3/envs/opencda/lib/python3.7/ctypes/init.py", line 364, in init self._handle = _dlopen(self._name, mode) OSError: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.27' not found (required by /home/anaconda3/envs/opencda/lib/python3.7/site-packages/open3d/cpu/pybind.cpython-37m-x86_64-linux-gnu.so)

I searched in google and found that it maybe the problem of open3d which uses glibc 2.27 Ubuntu16.04 seems to not be supported anymore. Ubuntu 16.04 use only glibc 2.23

so Am I must upgrade my Ubuntu to 18.04?

Hi, thanks for reporting this. Actually, I think you can just downgrade your open3d to a previous version to give a try first.

Hi, I downgrade the open3d to 0.9.0.0 It has another error:

File "/home/OpenCDA/opencda/core/sensing/perception/perception_manager.py", line 345, in init self.o3d_vis = o3d_visualizer_init(vehicle.id) File "/home/OpenCDA/opencda/core/sensing/perception/o3d_lidar_libs.py", line 104, in o3d_visualizer_init top=270) RuntimeError: [Open3D ERROR] GLFW Error: GLX: Failed to create context: GLXBadFBConfig

I think maybe the open3d version is too old. So I modified the "single_2lanefree_carla.yaml" line 20,  change lidar_visualize from true to false.   It worked.

What gpu and driver you are using?
