For multi-robot warehouse (RWARE) environment, the version of gym is suggeted to be 0.21 according its the offcial instruction (https://github.com/semitable/robotic-warehouse/blob/master/setup.py)..

Hence, when you run this environment with XuanCe, you should downgrade the version of gym by typing pip install gym==0.21 That will help you solve the problem.
