I've install mujoco-200 following the instruction, and I run "python launch_experiment.py ./configs/cheetah-dir.json". It should work as it is mentioned in Readme("For the task distributions in which the reward function varies (Cheetah, Ant, Humanoid), install MuJoCo200."), but still report lacking dependencies of Mujoco131. In fact, I think the code contains a mandatory check on the version of mujoco. Maybe the README is inconsistent with the actual situation.
