AttributeError: module 'numpy' has no attribute 'object'. `np.object` was a deprecated alias for the builtin `object`. To avoid this error in existing code, use `object` by itself. Doing this will not modify any behavior and is safe. The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at: https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations

这个错误消息表明在代码中使用了`np.object`，但是在最新版本的NumPy中已经将其废弃并删除了。为了解决这个问题，你可以将`np.object`替换为`object`。这样做不会改变任何行为，并且是安全的。你可以参考NumPy 1.20的发布说明页面，获取更多详细信息和指导：https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations
