Breaking Change to LangChain Caused Error in NLQ Application #32

Closed garystafford-aws closed 11 months ago

Based on the LangChain Issue: This is likely due to SQLDatabaseChain being migrated over to langchain_experimental package. See related PR: https://github.com/langchain-ai/langchain/pull/8425

The package can now be imported using:

from langchain_experimental.sql import SQLDatabaseChain

Error:

ImportError: cannot import name 'SQLDatabaseChain' from 'langchain.chains'
