我收到 Pydantic 导入错误：即使使用 ydata 分析后，基本设置也已移动

Question

这是我的代码。

from ydata_profiling import ProfileReport as pf

这是错误

我唯一尝试的就是导入 ydata-profiling 库。我希望这个库能够通过使用 ydata-profiling 来工作，因为 Pandas-profiling 已经过时，并且 Pydantic 已经推出了其版本 2。 我正在尝试对其进行探索性数据分析（EDA）。

Answer 1

您的 ydata_profiling 版本仅适用于较旧的 pydantic 版本。从堆栈跟踪中的链接： https://docs.pydantic.dev/2.3/errors/usage_errors/#import-error

当您尝试导入曾经存在的对象时，会引发此错误 在 Pydantic V1 中可用，但在 Pydantic V2 中已被删除。

请参阅迁移指南了解更多信息。

如果将 ydata_profiling 升级到最新版本无法修复问题，则需要降级 pydantic-version。如果你的代码库中需要这样的技巧，我强烈建议使用

venv

来管理你的 python 包。
