AIstuido 用notebook跑PARL的DQN程序报错

---------------------------------------------------------------------------
ImportError Traceback (most recent call last)

ImportError: cannot import name 'DQN' from 'parl.algorithms' (/opt/conda/envs/python35-paddle120-env/lib/python3.7/site-packages/parl/algorithms/__init__.py)

说找不到DQN，可是我已经通过

!pip uninstall -y parl
!pip install parl

把PARL库换成2.0.5版本了啊
