Old version of Mujoco?

[ElRoberto538]

Hi, I was curious why the mujoco package is set to "mujoco>=2.3.7,<3.0.0"? This errors on install on macos, but the newest release installs fine and seems to work fine, is there a reason not to bump it to 3.3.5?

Indeed, I am experiencing the same problem also for gym-aloha and gym-xarm, probably the <3.0.0 upper bound was added to avoid possible breaking changes in mujoco 3.*, but as mujoco 3.* seems to work fine, we can probably raise that to <4.0.0. The main downside is that this results in a really old mujoco version being installed if one installs lerobot[all].

On the gym-xarm, I opened a PR to propose relaxing the upper bound: huggingface/gym-xarm#13 .
