在AI Studio 的脚本模式运行DQN例程报错
我在run.py中重新安装依赖库
import os
import train
myCmd = 'pip uninstall -y parl'
os.system(myCmd)
myCmd = 'pip uninstall -y gym'
os.system(myCmd)
myCmd = 'pip uninstall -y pandas scikit-learn'
os.system(myCmd)
myCmd = 'pip install gym'
os.system(myCmd)
myCmd = 'pip install parl'
os.system(myCmd)
myCmd = 'pip list --format=columns'
os.system(myCmd)
train.main()
但执行失败。例程代码在我个人电脑上运行没有问题，所以想问是不是AISTUDIO的配置有些问题呢？

hello，看起来像是gym版本的问题，你确认下本地的gym版本和aistudio上的版本，看下是否一致。

hi，按照您的指点我查看了gym版本
aistudio的gym和我本地的gym版本是一样的 都是0.25.2
parl都是2.0.5
我之前用我自己按照example改的程序会报找不到DQN的错误，所以我在想是不是我的AISTUDIO的操作哪里有问题
DQN例程的AISTUDIO项目地址 https://aistudio.baidu.com/aistudio/clusterprojectdetail/4482076
Hi，你可以尝试在运行 python train.py 之前执行以下安装操作
pip install gym==0.18.0
pip install paddlepaddle==2.3.1
pip install parl==2.0.5
python train.py
或者也可以体验一下我们整理的AIStudio例程（DQN解决CartPole问题） https://aistudio.baidu.com/aistudio/projectdetail/4375697
