ros-bridge couldn't fit into the latest CARLA

description

I'm using the Carla 0.9.15 in ROS2-humble in Ubuntu22.04.

When I launch the ros-bridge, I faced to the following logs and ros-bridge didn't work.

[bridge-1] [INFO] [1720767764.270699081] [carla_ros_bridge]: Trying to connect to localhost:2000

I notice the FETAL log is

Does it mean that we stiil can't use the ros-bridge with the latest Carla ?

I think you only have to modify the following file https://github.com/carla-simulator/ros-bridge/blob/master/carla_ros_bridge/src/carla_ros_bridge/CARLA_VERSION

There are several forks of the bridge that work nicely with Carla 15 and newer ROS versions. You might find some help in these repos.

@GoesM Hello, I also do a project that involve in carla ros bridge. The version we use that like you (Ubuntu 22.04, Carla 0.9.15, Humble). However, the carla ros bridge is not working. Can you give me the instruction in order to use it. Thank you

@Hynh4u what about the issue you've met ?

I just modify the following file https://github.com/carla-simulator/ros-bridge/blob/master/carla_ros_bridge/src/carla_ros_bridge/CARLA_VERSION with following context:

0.9.15

and it works.

@GoesM I have run it successfully but now I have a problem that I don't know how to run carlaue4 with a discrete graphics card(Currently I am using an integrated graphics card Intel UHD Graphics 630 and a discrete card Radeon RX 5500/5500M/Pro 5500M). Can u help me?

[oliver-schumann]

@Hynh4u at first check with nvtop (if you are on Ubuntu) on which card Carla is actually running.
If you run the simulator from docker (which is the recommended way) check the following doc:

https://carla.readthedocs.io/en/0.9.8/build_docker/

In docker run you can specify with --gpus the visible gpus.

Hi @oliver-schumann, when i check with nvtop, its show: No GPU is monitor. I run CarlaUE4 with the 'make launch' command and when i find the GPU card in terminal, i found the line: LogVulkanRHI: Display: Device 1: Intel(R) UHD Graphics 630 (CFL GT2)

and i want to run my CarlaUE4 with this AMD card
