Can't verify installation when building from source

[shrimo-d]

Following the installation steps "From Source" as described in the README fails at step 7 (Verify installation (and download Menagerie): python -c "import mujoco_playground")

Doing so yields an AttributeError:

Traceback (most recent call last):

            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

AttributeError: type object 'mujoco._enums.mjtEnableBit' has no attribute 'mjENBL_SLEEP'

This problem stems from mujoco-mjx. I guess some changes were done, that aren't working properly, so I tried to change the dependencies in the pyproject.toml file to include a previous version of mujoco and mujoco-mjx, but it resulted in:

Because only mujoco-mjx==3.3.8 is available and mujoco-mjx==3.3.8 depends on mujoco>=3.3.8.dev0, we can conclude that all
      versions of mujoco-mjx depend on mujoco>=3.3.8.dev0.
      And because playground==0.0.5 depends on mujoco-mjx and mujoco>=3.3.6.dev0,<3.3.8, we can conclude that playground==0.0.5 cannot
      be used.
      And because only playground[all]==0.0.5 is available and you require playground[all], we can conclude that your requirements
      are unsatisfiable.

Any help would be appreciated!

Manually downgrading mujoco and mujoco-mjx to 3.3.7 fixed it
