去修改aistudio上该项目的paddle环境，即在项目主界面的右边有“删除” “修改” “设置为公开”那里， 点击修改， 把通用框架修改为paddle 2.4.0版本或以上，保存，即可修复该import问题。

原因我猜是paddle新版的api兼容性问题，参考issue：import error

[akari0216]

经测试，最新版本的pgl运行模型会报bug，参见issueValueError: (InvalidArgument) argument (position 2) must be list of int, but got memmap at pos 0，建议是指定安装版本pip install pgl==2.2.4，paddle版本需2.2.0及以上即可

pip install pgl==2.2.4
Looking in indexes: http://mirrors.aliyun.com/pypi/simple
ERROR: Could not find a version that satisfies the requirement pgl==2.2.4 (from versions: 2.2.3)
ERROR: No matching distribution found for pgl==2.2.4
不知道为什么装不了2.2.4
