I'm using vscode to remotely connect to a linux server, doing some experiments with controlling carla using python. But encountered an error: RuntimeError: time-out of 5000ms while waiting for the simulator, make sure the simulator is ready and connected to localhost:2000. My python codes that encounter this error are as follows: 'try: self.world = self.client.get_world() except RuntimeError:

subprocess.Popen(self.carla_path) time.sleep(5)

self.client = carla.Client('localhost', 2000) self.client.set_timeout(5.0) self.world = self.client.load_world("Town04") self.spectator = self.world.get_spectator()'

does anyone encounter the same problem

[LandoFan]

yes, I am facing the same problem

[Youngzipper]

yes, I am facing the same problem

Have you got a solution? Or can you restart CARLA when crashes? I added the codes "subprocess.Popen(carla_path)" in my Python script to restart CARLA but failed.

[Youngzipper]

yes, I am facing the same problem

Oh sorry, more details I will provide. I encountered the crash when my RL codes reached about 35 epoches (40 mins). Complete error information is : (base) working_station:~/Carla$ ./CarlaUE4.sh 4.26.2-0+++UE4+Release-4.26 522 0 Disabling core dumps. Signal 11 caught.

Good bye. Segmentation fault (core dumped)

I am sorry, I am searching for solution too.

I am sorry, I am searching for solution too. @ Maybe we can have each other emails and communicate on CARLA later. My email is yzy.atom@gmail.com

carlaue4.exe may already be running in the background. End the carlaue4.exe task in Task Manager (Ctrl+Alt+Del) and try to run the script again.

@Youngzipper @LandoFan Hi, I encounter the same problem. My hardware is Ubuntu 20.4, Anaconda virtual environment for Python 3.7, Carla 0.9.11, with SSH remote connection to the computer. Here is my solution: Step1: Move to the root directory of carla (run it in your terminal/cmd): cd carla Step2: Run carla server before call it in your code: Importantly: you should explictly assign a port for it (see command-line options in the official document (search for "command-line" in the page) https://carla.readthedocs.io/en/latest/start_quickstart/#running-carla (run it in your terminal/cmd) ./CarlaUE4.sh -carla-rpc-port=3000 Step3: Run your code by(run it in your terminal/cmd): cd path_of_your_code_dir python yourcode.py Important: In your code, the port should be 3000! Do not close/kill carla server until your code ends.
