Carla simulator crashes while connecting about carla-autoware

[joel-mb]

Hi @pirate-lofy,
One issue I've seen in your log is that the ego_vehicle node is not receiving the world_info topic on time. Can you try setting the map first and then running autoware.

1. Start the server:

./CarlaUE4.sh -windowed -ResX=800 -ResY=600 -carla-server

2. Change to Town01 (the config.py in under the PythonAPI/util folder).

python config.py -m Town01

3. Run the carla-autoware agent.

Hi, @joel-mb , thanks for replying.
I tried to change the map many times using the config.py file but the simulator crashes after running the config.py file witth following error

4.24.3-0+++UE4+Release-4.24 518 0
Disabling core dumps.

and then I tried to change the map using the terminal parameter
/Game/Carla/Maps/Town01
but it doesn't change the map

@pirate-lofy which CARLA package are you using? Are you using 0.9.10.1?

[pirate-lofy]

Yes, I am using 0.9.10.1 pre-build release

Hi,
I am facing similar problem while trying to run Carla with Pylot. Following, is the full log of my Carla run:

The failure happened when I ran Pylot and I also confirmed that Pylot was successfully running, until it shutdown since it was not able to connect to Carla. Interestingly, Carla did not consume any GPU memory which is really odd!

I appreciate any help, if possible. Thanks.
