Problem About Train

[gnniaaa]

Hi! I wonder whether my running is true or not.
When I tried to run Main.py, I found that it finished quickly, that seems it didn't train. And when I made a debug, I found env.reset() always didn't work. And I got an error like this:
self.planner = Planner(self.scene.map_name)
AttributeError:map_name

This error didn't occur if I run carla_env.py directly.
Could you help me? Thank you so much!!!
