I want to implement stop generation button in my streamlit app please help. If the user clicks on the stop generation button the processing of response must stop. This is my code, please help!

User-provided prompt

if prompt := st.chat_input():
st.session_state.messages.append({“role”: “user”, “content”: prompt})
with st.chat_message(“user”):
st.session_state.user_prompt_count += 1
st.write(prompt)

# Add a button to allow the user to stop generation
if st.button("Stop Generation"):
    st.session_state.generation_enabled = False

Generate a new response if last message is not from assistant

if st.session_state.messages[-1][“role”] != “assistant” and st.session_state.generation_enabled:
with st.chat_message(“assistant”):
with st.spinner(“Thinking…”):
response = generate_llama2_response(prompt)

        placeholder = st.empty()
        full_response = ''

        if "error" in response:
            # Handle the error case
            error_message = response["error"]
            # Display the error message in a red background
            st.markdown(f'<div style="background-color: #ff0000; color: #ffffff; padding: 10px;">Error: {error_message}</div>', unsafe_allow_html=True)
        else:
            for item in response:
                # Convert the dictionary to a JSON-formatted string
                item_str = json.dumps(item, indent=2)
                full_response += item_str
                # Use st.json to display the JSON data
                placeholder.json(full_response)


message = {"role": "assistant", "content": full_response}
st.session_state.messages.append(message)

Try this implementation:

import streamlit as st

if "app_stopped" not in st.session_state:
    st.session_state["app_stopped"] = False 
elif st.session_state["app_stopped"]:
    st.session_state["app_stopped"] = False


def Running():
    with st.spinner("running"):
        time.sleep(60)

def stopRunning():
    st.session_state["app_stopped"] = True

if st.session_state["app_stopped"]:
    st.stop()

st.button("run", on_click=Running)

st.button("Stop", on_click=stopRunning)

In your case just add:

if not st.session_state.generation_enabled:
    st.stop()
