ERROR select_flag_test.py - NameError: name 'Any' is not defined

这个错误通常是因为你的代码中缺少了对 `typing` 模块的导入语句，而 `Any` 是 `typing` 模块中的一种特殊类型。

要解决这个问题，你需要在你的代码中导入 `typing` 模块，并使用 `typing.Any` 替换 `Any`，例如：

import typing

def foo(x: typing.Any) -> None:
    pass

如果你只想导入 `typing` 模块中的 `Any` 类型，可以使用以下导入语句：

from typing import Any

这样你就可以在代码中直接使用 `Any` 类型而不需要加上前缀 `typing.`，例如：

def foo(x: Any) -> None:
    pass

总之，要解决这个错误，你需要导入 `typing` 模块并使用 `typing.Any` 或者 `Any` 类型。

It seems like you are encountering a "NameError" in your code. The error message "name 'adfuller' is not defined" is indicating that the function "adfuller" is not recognized. This error is commonly seen when a function or variable is not defined in the current scope or is not imported from a module.

To resolve this error, you need to import the necessary library that contains the "adfuller" function. The "adfuller" function is part of the statsmodels library, so you can add the following import statement at the beginning of your code:

from statsmodels.tsa.stattools import adfuller

This should import the "adfuller" function and make it available for use in your code.

cannot find reference 'imread' in '__init__'.py

The error message suggests that the function `imread` is not defined in the `__init__.py` file of the module you are trying to import.

Here are a few things you can try to resolve this error:

1. Check if the module you are trying to import has `imread` function defined in any of its files. If not, you may need to install a package that provides this function or write your own implementation.

2. If the `imread` function is defined in a different file, make sure that you are importing it correctly in your code. For example, if `imread` is defined in a file called `image_utils.py`, you should import it in your code as follows:

   from image_utils import imread

3. Check if you have misspelled the function name or used the wrong case. Python is case-sensitive, so `imread` is not the same as `Imread`.

4. If you are still having trouble, try restarting your Python interpreter or IDE. Sometimes, errors can occur due to cached modules or old runtime environments.
