About the meaning of level

[gemcollector]

I'm sorry I wanna ask 3 very simple questions:

1. what does the "level" mean? Different levels have different visual background?
2. So if I set up the "num_level=500" ,does that mean I will train an agent on 500 different visual background game?
3. And how can I change to the generalization mode? just let the "num_level=0"?

Thx for your reply!~

1. For many of the environments they don't have just different visual backgrounds, but also different maps (so like boxes in difference places, see coinrun for a good example)
2. Yeah, you can try this out with the interactive script, by setting num_level=1 or num_level=2.
3. I believe that is correct.
