Hi, A similar issue is open on the gym repo. But I think that box2d is only used for lunarlander environment so you should be able to use MuZero without box2d, (just remove it from requirements.txt).

@gWOLF3 I ran into the same issue too, If you do want to have box2d can just run brew install swig beforehand and the error goes away
