Issue with running train_trials.py due to unsupported 'gym.spaces.dict.Dict'

[selenak666]

stable-baselines3 does not support '<class 'gym.spaces.dict.Dict'>', so when I run trials/scripts/train_trials.py, I get the following error

assert not hasattr(obs_space, "spaces"), f"Unsupported structured space '{type(obs_space)}'"

AssertionError: Unsupported structured space '<class 'gym.spaces.dict.Dict'>

How can the code be executed?

@selenak666 hi, I am also trying, being debug for a while for several issues and still can not train successfully.
could you try to use stable-baselines3 1.6.2 version?
