Example Code

import langchain from langchain_community.chat_models import ChatHunyuan from langchain_core.messages import HumanMessage

print(langchain.version) hunyuan_app_id = "**" hunyuan_secret_id = "****" hunyuan_secret_key = "***" llm_tongyi = ChatHunyuan(streaming=True, hunyuan_app_id=hunyuan_app_id, hunyuan_secret_id=hunyuan_secret_id, hunyuan_secret_key=hunyuan_secret_key) print(llm_tongyi.invoke("how old are you"))
