you can change your xosc file to test whether the `box` exists ``` ``` ===> ``` ```

In fact, py_trees version: 0.8.13 using `\u2713` a check sign in py trees indicates success,but in the new version `o` is used to indicate success

Perhaps you can try looking at the xodr information at https://odrviewer.io/ and determine the coordinates

I also use a loop on the scenario_runner layer for a multi-scenario call，I wonder if there's a better strategy？

You can first check whether the trafficManagerPort you set is used. If so, please kill the related process first. If not, try to restart carla and connect again

Try using world postion and then changing carla's get_waypoint method to position it to a custom location

Run python in your terminal, import xmlschema, and if it fails, install xmlschema using your package manager

Is there an error screenshot

Are you using npc vehicle control? if yes: Check the output :[code](https://github.com/carla-simulator/scenario_runner/blob/70426c198cc2c8ffa7a070445d6f2a9ac9f665f5/srunner/scenariomanager/actorcontrols/npc_vehicle_control.py#L107C1-L110C60)

l1 = headA l2 = headB while l1 != l2: l1 = l1.next if l1 else headB l2 = l2.next if l2 else headA return l1
