This is probably due to our update on RLSchool / MetaGym environment.
Starting from RLSchool 1.0.3, we are changing the entrance from

rlschool.make_env("XXX")

to

import gym
import metagym.quadrupedal
gym.make("XXX")

To make sure the current version of PaddleRobotics work for you, please ensure that your are installing rlschool==1.0.2 by using

pip install rlschool==1.0.2

If you are using the newest version of MetaGym.
please check https://github.com/PaddlePaddle/MetaGym/tree/master/metagym/quadrupedal
