TypeError: __init__() missing 1 required positional argument: 'observation_space' #15

Hi,

When I follow the usage

"" from gym_extensions.continuous import mujoco env = gym.make("HalfCheetahGravityHalf-v0") """

It shows the error:

TypeError: init() missing 1 required positional argument: 'observation_space'

I wonder is it caused by the version of gym? I used 'gym-0.25.2' for the experiment.

try this:

pip uninstall gym
pip install gym==0.23.1

According to setup.py in D4RL, gym version must be lower than 0.24
