Problems running the script run_bridge.py

[Hffmann]

I can't run the script with any python version, running with python 2 outputs incompatibilities with the generated egg (python 3.8 in my case) and running with python 3 generates incompatibility errors when using importlib.

In which version did you build the PythonAPI ?

Hi! There are different versions of the carla python api egg files. One for python2 and one for python3. You need to use python2 for compatibility with the cyber python api.

It worked perfectly !. Now i am facing an issue when running dreamview, when i attempt the connection and open dreamview i receive the log:

E1006 12:01:20.078724 6825 file.cc:73] [dreamview] Failed to open file /apollo/modules/map/data/carla_town03/default_end_way_point.txt in text mode.

In dreamview theres no presentation of the map and the task bar sensors are disabled.

It may be related to the use of the latest carla version, i'd appreciate your opinion.

That dreamview error is normal and shouldn't cause any issues. Things will remain greyed out and you won't see the map until apollo receives localization from the simulator. If you're following the step-by-step guide, that should happen when you run the manual_control.py script.

Sorry for extending this thread with so many points, but i followed all steps and i end up with the following results:

As seen, carla, apollo and the bridge seem to be working accordingly although the logs in the right (first image) indicate an error managing the lidar sensor (run_bridge script), and the manual control script outputs the following one, right down below.

When enabling the sim control i end up with the map presentation with a random location:

I am using carla0.9.10.

[AngelJA]

Not sure, but this could be related to the Carla version. I've only tested this up to 0.9.9 so try that. It makes sense that you don't see the map until you turn on sim control, since the bridge script is crashing.

I see there were some Lidar related changes in 0.9.10 so the bridge may need to be updated if that is what's causing your error.

HI @AngelJA, could you please tell me which CARLA versions work with this cyber bridge 5.0 you have set?

I am testing just 0.9.6 with Docker, because the 0.9.6 installation from source is too old and the rquired libraries and compilers conflicts are crashing my ubuntu 20.04...

Does the bridge works with the simulator running locally too? and which versions of CARLA does it work:

1. Simulator in Docker?

2. Simulator Locally?

3. To work with simulator locally...must Apollo Stack and Carla-Apollo bridge be installed locally? Or an image from Apollo container and Carla-Apollo bridge container (Docker) are enough to communicate with CARLA simulator locally?

Thanks in advance
