Localization stuck on "uninitialized"

[hatem-darweesh]

Can you check:
1-
"export PYTHONPATH=$PYTHONPATH:${CARLA_ROOT}/PythonAPI/carla/dist/carla-0.9.13-py2.7-linux-x86_64.egg"
you need to download the python egg for 3.10 from the mentioned link. and change the above export to the new egg name.

2- Download the Pointcloud PCD map and create a map folder contains both .osm and .pcd files.

I recommend you familiarize yourself with autoware.universe fist by running both the planning and rosbag simulation mentioned in the documentation.

Thanks for responding.

1. You helped me realise that this export does nothing, I don't have carla-0.9.13. It should have looked like this: export PYTHONPATH=$PYTHONPATH:${CARLA_ROOT}/PythonAPI/carla/dist/carla-0.9.15-py3.7-linux-x86_64.egg

This export causes this error:

The issue is that I can't seem to find the python egg for 3.10. The latest version I could find is the egg file for 3.7. If anyone has found it for 3.10 please let me know.

2. I'll will this suggestion

You need to follow the instruction from the "humble" branch

https://github.com/hatem-darweesh/op_bridge/blob/ros2-humble/README.md

Thanks for providing the link for the Python3.10 egg file. The homepage of op_bridge repo shows a different README.md than the one you linked above. I think that's why I couldn't find this egg file.

I retried again using export PYTHONPATH=$PYTHONPATH:${CARLA_ROOT}/PythonAPI/carla/dist/carla-0.9.15-py3.10-linux-x86_64.egg and getting similar errors as before:

Most of the errors are related to base_link and tf

I managed to partially resolve the issue above. Some errors I solved:

[map.map_hash_generator]: [/home/dbat/carla-0.9.15/op_agent/autoware-contents/maps/Town01/pointcloud_map.pcd] is neither file nor directory

Downloaded pcd map from carla simulator maps, moved it to the location it was searching for and renamed to pointcloud_map.pcd

pip install Werkzeug==2.2.0 fixed it.

I am able to see the map and set '2D goal pose'. :)

The only issue now is that I sometimes need to rerun the program since initialization is inconsistent. Relevant errors:

I'd love to be able to at least move the car with '2D Pose Estimate'.

After adding two files from this pr by @cfs4819, I can now successfully use '2D Pose Estimate' .

Thanks Hatem-darweesh and cfs4819
