调用huggingface上的mistral模型遇到下面的问题

TypeError: unsupported operand type(s) for |: '_UnionGenericAlias' and '_UnionGenericAlias'

出现问题的原因是我用的是python3.9，但是要python3.10才能解决问题，我用gpt-4o+search功能解决了这个问题

The error message TypeError: unsupported operand type(s) for |: '_UnionGenericAlias' and '_UnionGenericAlias' typically arises when attempting to use the bitwise OR operator (|) between two type hints in Python versions prior to 3.10. In these versions, the | operator isn't supported for combining type hints, leading to this TypeError.

Understanding the Issue:

In Python 3.10 and later, PEP 604 introduced the ability to use the | operator to denote union types in type hints. For example:

def process_data(data: int | str) -> None:
    ...

However, in earlier versions of Python, this syntax isn't recognized, and attempting to use it results in the aforementioned TypeError.

Upgrade to Python 3.10 or Later:

If possible, upgrading your Python environment to version 3.10 or newer will allow you to use the | operator in type hints without encountering this error.
Use the Union Type Hint from the typing Module:

If upgrading isn't feasible, you can achieve the same functionality using the Union type hint from the typing module, which is compatible with Python versions 3.5 and above. Here's how you can rewrite the function signature:
```
from typing import Union

def process_data(data: Union[int, str]) -> None:
    ...
```
This approach ensures compatibility across Python versions that support the typing module.
