When does this happen?

IF ImportError related to missing classes when using langchain with third-party libraries like llama-index

How others solved it

THEN Ensure version compatibility either by downgrading langchain to 0.0.340 or 0.0.148, or by upgrading llama-index to its latest version. Conflicting dependencies between langchain and llama-index can cause import errors for classes like BaseCache or Document.

pip install langchain==0.0.340
