Amazon Bedrock Workshop - [Bug]

[codekiln]

Describe the bug
In the code cell below ### Invoke Langchain with Chain using BedrockChat class in 06_OpenSource_examples/05_OpenSource_agents/01_tools_agents.ipynb, there's a deprecation warning:

/Users/pnore/Library/Caches/pypoetry/virtualenvs/genai-langserve-IOUqE2kZ-py3.11/lib/python3.11/site-packages/langchain_core/_api/deprecation.py:119: LangChainDeprecationWarning: The class `BedrockChat` was deprecated in LangChain 0.0.34 and will be removed in 0.3. An updated version of the class exists in the langchain-aws package and should be used instead. To use it run `pip install -U langchain-aws` and import as `from langchain_aws import ChatBedrock`.

Also, in the code cell that contains llm_math_chain({'question': 'text 4**5'}) there's another more pressing deprecation:

LangChainDeprecationWarning: The method `Chain.__call__` was deprecated in langchain 0.1.0 and will be removed in 0.2.0. Use invoke instead.
  warn_deprecated(

In the cell ask_agent("can you check the weather in Marysville WA for me?", react_agent_llm) there's another langchain 0.2.0 deprecation warning:

LangChainDeprecationWarning: The function `initialize_agent` was deprecated in LangChain 0.1.0 and will be removed in 0.2.0. Use Use new agent constructor methods like create_react_agent, create_json_agent, create_structured_chat_agent, etc. instead.
  warn_deprecated(

Note: the code continues to function for now.

Other places in this notebook (correctly, for now) use from langchain_aws.chat_models.bedrock import ChatBedrock.

To Reproduce
Steps to reproduce the behavior (or some version of this):

1. Go to 06_OpenSource_examples/05_OpenSource_agents/01_tools_agents.ipynb
2. Run all cells above ### Invoke Langchain with \Chain` using BedrockChat class`
3. Run the code cell immediately before
4. See warning
