The error you're encountering typically occurs when you're trying to access the `__all__` attribute of the `sqlalchemy` module. However, the `sqlalchemy` module does not have an `__all__` attribute.
It seems like there might be a misunderstanding or incorrect usage of the `__all__` attribute. The `__all__` attribute is used to define the public interface of a module, specifying which names should be imported when using the `from module import *` syntax. It is not a general attribute available in all modules.
To resolve this issue, you can do the following:
1. Remove or modify the code that tries to access the `__all__` attribute of the `sqlalchemy` module. It is not necessary and may not be applicable in this context.
2. Ensure that you are using the correct syntax when importing from the `sqlalchemy` module. For example, to import the `create_engine` function from `sqlalchemy`, you would use:
```python
from sqlalchemy import create_engine
```
If you provide more details or code snippets related to the issue, I can assist you further in resolving the problem.
