Bedrock models are no longer available (version 2.20.0)

[DzmitrySudnik]

Description

Bedrock modules are not available in UI, if I try to start jupyterlab with my old config where I have "default_language_model": "bedrock-chat:anthropic.claude-3-5-sonnet-20240620-v1:0", I'm getting an error on startup:

ValueError: No language model is associated with 'bedrock-chat:anthropic.claude-3-5-sonnet-20240620-v1:0'.

On version 2.19.1 Bedrock models are there.

Reproduce

1. Open settings on UI for the latest jupyter-ai and Bedrock models are not there

Expected behavior

Context

• JupyterLab version: 2.20.0

@DzmitrySudnik Hey Dzmitry! This is due to the recent migration to langchain-aws from langchain-community, as the AWS code in langchain-community is no longer maintained. To access Bedrock & SageMaker Endpoint models, you now have to install langchain-aws via:

pip install langchain-aws

in your Jupyter AI environment.

@dlqqq Ah.. Let me try that. I'll close the issue if it's resolved. Thanks for a quick response!

[DzmitrySudnik]

Yep, that was it. Closing the issue. Thanks again!
