Check the code for `Humanoid-v5` for examples of using extra sensors The documentation for hopper can be found here: https://gymnasium.farama.org/main/environments/mujoco/hopper/#observation-space Note: We have launched [gymnasium](https://github.com/Farama-Foundation/Gymnasium), a fork of Gym by...

Can you try replacing the entire body of `def _reset_sim(self):` with a single [mj_resetData](https://mujoco.readthedocs.io/en/stable/APIreference/APIfunctions.html#mj-resetdata) ```py mujoco.mj_resetData(self.model, self.data) ```

1. your `test_same_env_determinism_rollout` is effectively a reimplementation of [`gymnasium.utils.env_match.check_environments_match`](https://github.com/Farama-Foundation/Gymnasium/blob/main/gymnasium/utils/env_match.py), I do not believe it has any additional utility, if you agree remove it. You can use this test instead, to...

1) yes bump all changed environments 2) deprecation warning are handled by `gymnasium.make` 3) yes, documentation should be changed in this PR

Since shadow envs are not be affected by the change we do not have to worry about them we should verify that they remain unchanged though

@rodrigodelazcano What is the policy for keeping old verisons of environments? In this case the change is practically small. And should not cause problems with comparing training performance, reusing policies...

@amacati waiting for `gymnasium==1.0.0a2` which should be out soon(ish)

Note: I changed the changelog in the documentation to be shorter

I can replicate the results on my machine, note: during testing we use `atol=0.00001` https://github.com/Farama-Foundation/Gymnasium/blob/72cfbc204beca309579681b1201990a3d706e070/gymnasium/utils/env_checker.py#LL57 I expanded the test to cover all robotics environments ```py import gymnasium import numpy as...

Seems to affect all `RobotEnv` environments ```py FetchSlide-v1 FetchSlide-v2 FetchPickAndPlace-v1 FetchPickAndPlace-v2 FetchReach-v1 FetchReach-v2 FetchPush-v1 FetchPush-v2 HandReach-v0 HandReach-v1 FetchSlideDense-v1 FetchSlideDense-v2 FetchPickAndPlaceDense-v1 FetchPickAndPlaceDense-v2 FetchReachDense-v1 FetchReachDense-v2 FetchPushDense-v1 FetchPushDense-v2 HandReachDense-v0 HandReachDense-v1 ```
