Question about carla env

[csufangyu]

I'm trying to run carla_env, I ran bash scripts/carlatrain.sh directly and encountered the problem:
pygame 2.1.2 (SDL 2.0.16, Python 3.8.18) Hello from the pygame community. https://www.pygame.org/contribute.html workspace: /raid/fangyu_data/RL-ViGen/exp_local/2024.01.29/164236_action_repeat=2,feature_dim=50,lr=1e-4,nstep=1,num_train_frames=1001000,save_snapshot=True,save_video=False,seed=3,task=carla,use_tb=False,use_wandb=False,wandb_group= Error executing job with overrides: ['task=carla', 'seed=3', 'action_repeat=2', 'use_wandb=False', 'use_tb=False', 'num_train_frames=1001000', 'save_snapshot=True', 'save_video=False', 'lr=1e-4', 'feature_dim=50', 'nstep=1', 'wandb_group='] Traceback (most recent call last): File "carlatrain.py", line 262, in main workspace = W(cfg) File "/raid/fangyu_data/RL-ViGen/carlatrain.py", line 51, in __init__ self.setup() File "/raid/fangyu_data/RL-ViGen/carlatrain.py", line 71, in setup self.train_env = carla_make(action_repeat=self.cfg.action_repeat) File "/raid/fangyu_data/RL-ViGen/wrappers/carla_wrapper.py", line 109, in carla_make env = make_env_10(action_repeat) File "/raid/fangyu_data/RL-ViGen/./wrappers/carlaenv/utils.py", line 34, in make_env_10 env = CarlaEnv10(cfg_dict) File "/raid/fangyu_data/RL-ViGen/./wrappers/carlaenv/carla_env_10.py", line 263, in __init__ self.world = self.client.load_world(cfg_dict['map']) # change map here RuntimeError: time-out of 500000ms while waiting for the simulator, make sure the simulator is ready and connected to localhost:2018
I followed carla_README.md and wrote the code:

from carlaenv.utils import make_env_10
action_repeat = 2
env = make_env_10(action_repeat)

I have encountered the same problem. Can you please help me to solve it? Thank you

Hi there,
Sorry for the late reply due to the paper submission lol. Have you tackled this issue now? I think it may be caused by port conflict. Could you change to another port number for both port and traffic port?

Thanks your reply! I changed the both port and traffic port number, but it is not usefull.

There are some potential reasons:

1. Do you start the Carla engine correctly? You should use the same in the config file.
2. I suppose you may not install some dependencies. Here is a list I installed in my docker container to run the code:

sudo apt-get install xdg-user-dirs

sudo apt-get install libpng16-16

sudo apt-get install libjpeg-turbo8

sudo apt install libtiff5

sudo apt-get install libxerces-c3.2

You can also check the official docs from CARLA: https://carla.org/2020/09/25/release-0.9.10/ to find out whether someone else met the same issue.
