When does this happen?

IF ImportError: cannot import name 'BaseCache' from 'langchain' when using older versions of llama-index with LangChain.

How others solved it

THEN Use the correct import path 'from langchain.schema.cache import BaseCache' instead of the deprecated path. Alternatively, downgrade langchain to version 0.0.340 or upgrade llama-index to the latest version to align dependencies.

from langchain.schema.cache import BaseCache
