UnboundLocalError: local variable 'eval_manager' referenced before assignment about opencda HOT 13 CLOSED

I met the same problem. And i also met another problem:

RuntimeError: time-out of 10000ms while waiting for the simulator, make sure the simulator is ready and connected to localhost:2000

from opencda.

When you saw this issue, the root cause is not exactly this issue. Typically, it is caused by some other problems that happened before the evaluation manager is created, and when the codes go to the finally block this issue will raise as evaluation manager hasn't been created yet. So please paste the full error message here so I can help you.

Because I have not install carla in canda, and then I did it ,but now the question is changed as below..

Can you show me your running command, OS system version and Carla version?

from opencda.

Also, did you install opencda with the yaml file we provided?

from opencda.

@DerrickXuNu Thanks a lot. It seems I have find the root cause.Because in the environment.yaml and requirements.txt, the open3d has no version information, so pip default install 0.13.0. when I install open3d not higher than 0.10.x, The Porblem has solved.So Maybe there is some incompatibility problem..

from opencda.

I am using 0.13.0 and it works fine. I guess there is incompatibility between your system and Open3d. Anyway, please let me know if you have further questions

I met the same problem. And i also met another problem:

徐博士，我跑这个代码的时候也遇到了这个问题，local variable 'eval_manager' referenced before assignment，但好像不是上述的问题。
1、当时安装的时候，export CARLA_HOME=/path/to/your/CARLA_ROOT，这里面CARLA_ROOT就是CARLA_0.9.11的地址吗。
2、完整报错信息：(opencda) user@user-ThinkStation-P520:/lihaoming/OpenCDA$ python opencda.py -t single_2lanefree_carla -v 0.9.11

Did you start Carla simulators first?

我运行：
‘/CarlaUE4.sh'
4.24.3-0+++UE4+Release-4.24 518 0
Disabling core dumps，能正常启动的。
我运行您上述的python opencda.py-t single_town06_carla --apply_ml，会出现Town06 is not found in your CARLA repo! Please download all town maps to your CARLA repo! 这样的报错，我已经下载了那个additional map也替换到了原来的文件夹里。
