When does this happen?

IF When importing AmazonTextractPDFLoader or other langchain_community document loaders, an AttributeError: module 'sqlalchemy' has no attribute 'Select' occurs.

How others solved it

THEN Upgrade SQLAlchemy to version 2.0.0 or later. This ensures the `sa.Select` reference used in the `SQLDatabaseLoader` type hint resolves correctly. Run `pip install sqlalchemy==2.0.0` or `pip install -U 'SQLAlchemy>=2'`.

pip install -U 'SQLAlchemy>=2'
