Evaluation in simulation报错

[JeffXu1]

使用python train.py命令评估模型时报如下错误 python train.py --task_mode stairstair --eval 1 --load data/model/StairStair_3_itr_960231.pt [10-20 10:50:54 MainThread @logger.py:242] Argv: train.py --task_mode stairstair --eval 1 --load data/model/StairStair_3_itr_960231.pt pybullet build time: Oct 11 2021 20:59:00 /home/xh/PycharmProjects/pythonProject2/venv/lib/python3.7/site-packages/rlschool-1.0.2-py3.7.egg/rlschool/quadrupedal/robots/a1.py:94: RuntimeWarning: invalid value encountered in arccos (2 * l_low * l_up)) Traceback (most recent call last): File "train.py", line 508, in main() File "train.py", line 309, in main enable_action_filter=args.enable_action_filter) File "/home/xh/PycharmProjects/pythonProject2/venv/lib/python3.7/site-packages/rlschool-1.0.2-py3.7.egg/rlschool/init.py", line 17, in make_env raise Exception("rlschool.make_env is deprecated.

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
