After installing:

!pip install --quiet langchain_aws langchain_community

Then, running:

from langchain_aws import ChatBedrockConverse

messages = [
    (
        "system",
        "You are a helpful assistant that shapes sentences into poetic form. Translate the user sentence.",
    ),
    ("human", "I love programming."),
]

llm = ChatBedrockConverse(
    model='us.anthropic.claude-3-sonnet-20240229-v1:0',
    temperature=0,
    max_tokens=None,
    client=bedrock_runtime,
)

print(llm.invoke(messages).content)

I am getting the error:

---------------------------------------------------------------------------
