Error in mujoco_multi.py

[Duke-Allen]

I notice that the function close is raise NoImplementedError at class MujocoMulti in mujoco_multi.py. I want to know if it is means to be implemented by ourselves? If so, how can I implement it? Could you help me please?
Thanks for your reply!

The Close Function closes the render window, you generally do not have to call it on MuJuCo based environments

This is the solution, if you want it anyway:
