Unsupported structured space 'gymnasium.spaces.dict.Dict'

I am trying to run your code with stable-baselines3 (code under examples->train_push.py), it seems like stable-baselines does not support the observation space structure defined in gymnasium. How am I suppose to solve this problem?

` Traceback (most recent call last): File “/home/wxia612/panda-gym/examples/train_push.py”, line 10, in <module> model = DDPG(policy=“MultiInputPolicy”, env=env, replay_buffer_class=HerReplayBuffer, verbose=1) File “/home/wxia612/.local/lib/python3.8/site-packages/stable_baselines3/ddpg/ddpg.py”, line 85, in init super().init( File “/home/wxia612/.local/lib/python3.8/site-packages/stable_baselines3/td3/td3.py”, line 103, in init super().init( File “/home/wxia612/.local/lib/python3.8/site-packages/stable_baselines3/common/off_policy_algorithm.py”, line 111, in init super().init( File “/home/wxia612/.local/lib/python3.8/site-packages/stable_baselines3/common/base_class.py”, line 179, in init env = self._wrap_env(env, self.verbose, monitor_wrapper) File “/home/wxia612/.local/lib/python3.8/site-packages/stable_baselines3/common/base_class.py”, line 228, in _wrap_env env = DummyVecEnv([lambda: env]) File “/home/wxia612/.local/lib/python3.8/site-packages/stable_baselines3/common/vec_env/dummy_vec_env.py”, line 29, in init self.keys, shapes, dtypes = obs_space_info(obs_space) File “/home/wxia612/.local/lib/python3.8/site-packages/stable_baselines3/common/vec_env/util.py”, line 67, in obs_space_info assert not hasattr(obs_space, “spaces”), f"Unsupported structured space ‘{type(obs_space)}’" AssertionError: Unsupported structured space ‘<class ‘gymnasium.spaces.dict.Dict’>’
