Expected 'Iterator' as the return annotation for `__iter__` of SMILESParser, but found typing.Any

This error message means that in the `SMILESParser` class, the `__iter__` method should have a return annotation of `Iterator`, but instead it has been annotated with `typing.Any`.

To fix this error, you should change the return annotation of the `__iter__` method to `Iterator`. Here's an example:

from typing import Iterator

class SMILESParser:
    def __init__(self, smiles: str):
        self.smiles = smiles
    
    def __iter__(self) -> Iterator:
        # implement your iterator here
        yield ...

By annotating the `__iter__` method with `Iterator`, you are indicating that this method returns an iterator object.

TypeError: Expected 'Iterator' as the return annotation for `__iter__` of SMILESParser, but found typing.Any

我不确定我是否理解您的问题，请问您可以再解释一下吗？如果您在使用SMILESParser时遇到了TypeError，请检查是否在定义__iter__方法时正确地使用了迭代器作为返回注释。如果您仍然无法解决问题，请查看错误消息以获取更多信息。

报错如下“ Expected 'Iterator' as the return annotation for `__iter__` of SMILESParser, but found typing.Any”，是什么问题应该如何修改

这个报错是因为你在定义 `SMILESParser` 类时，使用了 `typing.Any` 作为 `__iter__` 方法的返回注解，但是实际上应该使用 `typing.Iterator`。

要修复这个问题，你需要将 `typing.Any` 替换为 `typing.Iterator`，代码示例如下：

import typing

class SMILESParser:
    def __init__(self, smiles: str):
        self.smiles = smiles
    
    def __iter__(self) -> typing.Iterator:
        # your implementation here

这样修改后就不会再出现这个报错了。
