Questions about MAMujoco #23

Hi, I'm very instersted in your work, and I want to test your MAT for MAMujoco. So, Do you have any experimental results or config of the MAMujoco Envirionment other than "HalfCheetah"?

hiya, thank you for your interesting, but we don't have results on other ma-mujoco map w.r.t MAT, since we use ma-mujoco mainly to simulate robot failure scenarios (for Table 3)....thus only choose the simplest case~

@morning9393 , thanks for your reply.

Can I ask one more question? I want to know whether get_obs_agent() in your MAMujoco is globally observable or partially observable, because there is differences between the obsk.py of original MAMujoco and that of yours.

@kaiyama12345679 hiya, Questions are always welcome~~ :))

in the file "train_mujoco.sh", you may find that we set agent_obsk=0, which means each agent obs returned by get_obs_agent() contained only the information corresponding to its own node, without neighbors, which is different from the original MA-Mujoco settings (usually agent_obsk=1 or agent_obsk=2, means it will contain information from the current node and all the nearest neighbor nodes with distances 1 or 2).

you can also change the agent_obsk if you would like to include more information into the agent obs~

hoping it might help you~

@morning9393, I'm sorry I didn't make the question clear enough. I would like to know why there is a difference between "build_obs()" in obsk.py and that of original MAMujoco, which seems to be the same as the commented out part in yours.
