NPC vehicles not seen

[SunFishlike]

Your work is truly attractive and I am trying to reproduce the benchmark. However, I see no NPC vehicles when I run the benchmark, just the ego-vehicle navigating for each episode. Is that normal? Is the benchmark working without NPC vehicles?

I'm using Carla 0.8.2 by running ./CarlaUE4.sh -carla-server.

I tried to solve it by myself, and I found that each episode will reset the client with default CarlaSettings. The default CarlaSettings should at least generated 20 NPC vehicles (but I see None). Anyway, I tried to solve this, but I have no idea now. Thank you very much if you have any idea.
