Run train_sac.py in map(a), and the car gets stuck in circling around the start location

[YYan99]

How can i solve it ? And how to train the car by using DQN, DDPG ? Thank you

This phenomenon of circling around also happened during my experiments but after some update times (maybe half an hour, or longer), the agent can jump out from this phenomenon.

I have a similar issue, the car hits the boundary and gets stuck for quite a while before moving back to road center, and in some cases gets stuck forever and couldn't get back to the road.
but I see additional error msg from terminal:
AttributeError: 'HUD' object has no attribute 'notification'.

I checked the file carla_tools.py from line 502 to 523, indeed there's no 'notification' attribute defined for the class 'HUD'. Could it be removed during certain commit?

Traceback pointing to /code/carla_tools.py line 726, which says
self.hud.notification("Collision with %r" % actor_type)
, see snapshot below.

Edit: I'm running train_sac.py with the train map (./CarlaUE4.sh /Game/Carla/ExportedMaps/train), the vehicle takes a right turn and hits the road boundary, then the error message above seem to loop endlessly.

@Yan81192 Hi Yan, how did you find the maps. I can't find any file related to the maps in this repository. Thank you for your help!

Hi, you can download this version CARLA, it contained the maps.
