def get_response(user_query, chat_history):
# Initialize the Hugging Face Endpoint
llm = HuggingFaceEndpoint(
huggingfacehub_api_token=api_token,
repo_id=repo_id,
process=process
)
chain = immediate | llm | StrOutputParser()
response = chain.invoke({
"chat_history": chat_history,
"user_question": user_query,
})
return response
- get_response operate: It’s the core of Yatra Sevak.AI’s response technology course of.
- Initialization: Yatra Sevak.AI connects to Hugging Face’s fashions utilizing credentials (api_token) and specifies the mannequin particulars (repo_id and process) for textual content technology.
- Interplay Circulate: Utilizing LangChain’s instruments (ChatPromptTemplate and StrOutputParser), it manages consumer queries (user_question) and retains observe of dialog historical past (chat_history).
- Response Technology: By invoking the mannequin , Yatra Sevak.AI processes consumer inputs to generate clear and useful responses, enhancing interplay for travel-related queries.
Step7: Managing Chat Historical past
# Initialize session state.
if "chat_history" not in st.session_state:
st.session_state.chat_history = [
AIMessage(content="Hello, I am Yatra Sevak.AI How can I help you?"),
]
# Show chat historical past.
for message in st.session_state.chat_history:
if isinstance(message, AIMessage):
with st.chat_message("AI"):
st.write(message.content material)
elif isinstance(message, HumanMessage):
with st.chat_message("Human"):
st.write(message.content material)
- Initializes and manages the chat historical past inside Streamlit’s session state, displaying AI and human messages within the consumer interface.
Step8: Dealing with Consumer Enter and Displaying Responses
# Consumer enter
user_query = st.chat_input("Kind your message right here...")
if user_query will not be None and user_query != "":
st.session_state.chat_history.append(HumanMessage(content material=user_query))
with st.chat_message("Human"):
st.markdown(user_query)
response = get_response(user_query, st.session_state.chat_history)
# Take away any undesirable prefixes from the response u ought to use these operate however
#earlier than utilizing it I requestto[replace("bot response:", "").strip()] mix 1&2 to run with out error.
#1.response = response.exchange("AI response:", "").exchange("chat response:", "").
#2.exchange("bot response:", "").strip()
with st.chat_message("AI"):
st.write(response)
st.session_state.chat_history.append(AIMessage(content material=response))
