When training multi-agent(train_all_copo_dist.py), observation type is not a Dictionary but a Box

[hyoonsoo]

When execute 'train_all_copo_dist.py', I was watching the process of generating train data.
in this project, because it is multi-agent observation, I think observation should be gym.Dict. (as wrote in ,annotation:
'metadrive/manager/agent_manager.py' )
but I checked obs_space generated in Box type.
and It was executed normally.(no errors)

How can I fix this problem? Or is this not a problem?

As you can see, the obs space here is single agent's obs space, so it's Box naturally.

Thank you for your kind answer.
I got mixed up.
