[Question]: Correct way to converse with agent with Python api

[val-life]

Describe your problem

I follow the Python API Reference but does not work. What should be the correct way to do so.

My Code:

from ragflow_sdk import RAGFlow
api = "<my api key>"
url = "http://<my ip>:9222"
rag_object = RAGFlow(api_key=api, base_url=url)

from ragflow_sdk import Agent
AGENT_ID = "4f1464d0b6ba11efb3570242ac120006"
session = Agent.create_session(AGENT_ID,rag_object)

while True:
    question = input("\n===== User ====\n> ")
    if question.lower() == "end":
        break
    print("\n==== Miss R ====\n")
    
    cont = ""
    for ans in session.ask(question, stream=True):
        print(ans.content[len(cont):], end='', flush=True)
        cont = ans.content

Error:

      7 cont = ""
----> 8 for ans in session.ask(question, stream=True):
      9     print(ans.content[len(cont):], end='', flush=True)
     10     cont = ans.content
