Update requirements.txt #43

Closed jimburtoft closed 11 months ago

jimburtoft commented 11 months ago

Description of changes:

Updated version requirements for langchain and boto3 to versions that have Bedrock support. (only important if you are using the Bedrock/Claude retriever). This fixes the error from langchain that says, "Error raised by bedrock service: 'Bedrock' object has no attribute 'invoke_model'"

There are other proposed changes to the requirements.txt, but there are also other issues with different versions of langchain. Better to only have the Bedrock users update, so I changed the REadme.
