----------------------
The
chat_repl()
function is designed to be an interactive chat Read-Eval-Print Loop (REPL) that allows you to have a conversation with the chat engine. It's designed to be used in a console or terminal environment where it can take input from the user, generate a response, and then wait for the next user input. This function maintains the context of the conversation, which allows it to refer back to previous questions or statements.
However, when you use the
chat()
function, it processes a single message and returns a response. If you want to maintain the context of the conversation, you need to ensure that you're using the same instance of the chat engine for each message and not resetting or recreating the chat engine between messages.
Here's an example of how you might use the
chat()
function in a conversation:
chat_engine = index.as_chat_engine(chat_mode="best" , verbose = True )
response1 = chat_engine.chat("Question 1 asked by the user.")
response2 = chat_engine.chat("Question 2 asked by the user.")
In this example, the chat engine should maintain the context between
response1
and
response2
, allowing it to refer back to "Question 1" when processing "Question 2".
If you want to start a new conversation, you can use the
reset()
function:
chat_engine.reset()
response = chat_engine.chat("Start of a new conversation.")
In this case, the chat engine won't have any context from before the
reset()
call.
Please note that the
chat_repl()
function is not designed to be used in a web application like Streamlit. It's designed for console or terminal use and it uses the
input()
function to read input from the user, which won't work in a web application. In a web application, you would typically use the
chat()
function to process individual messages from the user.
