Obstacle Detector class in Carla 0.9.11

Hello to all,

I am contacting you today because I have a problem with the implementation of the obstacle detector using the python API on Carla. Indeed, after configuration of the sensor, no car or pedestrian is detected during the simulation and if an object is detected the distance returned is always 0. I tried to debug by setting LINE-TRACE -DEBBUG to true but it is not visible.

Is there anyone in the community who has a solution to this problem?

I thank you in advance for your collaboration
