Python 3.9

Code to reproduce:

import os
# set env for prompt builder
os.environ["BEDROCK_PROMPT"] = "anthropic"
os.environ["AWS_REGION"] = "us-east-1"
os.environ["AWS_ACCESS_KEY_ID"] = "xxx"
os.environ["AWS_SECRET_ACCESS_KEY"] = "xxx"

from easyllm.clients import bedrock
from easyllm.schema.base import ChatMessage

response = bedrock.ChatCompletion.create(
    model="anthropic.claude-v2",
    messages=[
        ChatMessage(role="user", content="What is 2 + 2?"),
    ],
    temperature=0.9,
    top_p=0.6,
    max_tokens=1024,
    debug=False,
)
print(response)

Result:
