Hi,<br><br>I would like to use the MuJoCo implementation of Hopper, which has obs_dim=11 and action_dim=3. However, when making the environment with gym.make('HopperMuJoCoEnv-v0'), it returns the PyBullet implementation (HopperPyBulletEnv-v0) which has obs_dim=15 and action_dim=3. How can I access the MuJoCo implementation (<a href="https://github.com/benelot/pybullet-gym/blob/master/pybulletgym/envs/mujoco/envs/locomotion/hopper_env.py" class="postlink">https://github.com/benelot/pybullet-gym ... per_env.py</a>)?<p>Statistics: Posted by <a href="https://pybullet.org/Bullet/phpBB3/memberlist.php?mode=viewprofile&amp;u=13652">garcieri</a> — Wed Jul 08, 2020 11:20 am</p><hr />
