Is there any tools for changing the hyperparameter of the mujoco environment? Such as changing the gravity of the hopper-v3 environment?

>>> import gymnasium
>>> env = gymnasium.make("Hopper-v5")
>>> env.unwrapped.model.opt.gravity  # change this

We have launched gymnasium, a fork of Gym by the maintainers where all maintenance and improvements will happen moving forward.
