In the above notebook, there is small bug where we are importing ChatOpenAI class from deprecated version of LangChain langchain.chat_model not from langchain_openai.

Had to change:

from langchain.agents import AgentType, initialize_agent
from langchain.chat_models import ChatOpenAI
from langchain.memory import ConversationBufferWindowMemory

llm = ChatOpenAI(model="gpt-3.5-turbo-1106")

To

from langchain.agents import AgentType, initialize_agent
from langchain_openai import ChatOpenAI
from langchain.memory import ConversationBufferWindowMemory

llm = ChatOpenAI(model="gpt-3.5-turbo-1106")
