I am new to python and streamlit and I am creating a bot to answer based on a vectorstore and i am using Langchain too. This is my part for the streamlit UI code and although I initialize the session state, I'm having an error related to it. if "generated" not in st.session_state: st.session_state["generated"] = [] if "past" not in st.session_state: st.session_state["past"] = [] if "stored_session" not in st.session_state: st.session_state["stored_session"] = [] def get_text(): input_text = st.text_input("You: ", st.session_state.get("input", "Hello, how are you?"), key="input", placeholder="Your Notion bot, ask me anything") return input_text def new_chat() save = [] for i in range(len(st.session_state['generated'])-1, -1, -1): save.append("User:" + st.session_state["past"]) save.append("Bot:" + st.session_state["generated"]) st.session_state["stored_session"].append(save) st.session_state["generated"] = [] st.session_state["past"] = [] st.session_state["input"] = "" st.sidebar.button("New Chat", on_click=new_chat) user_input = get_text() if user_input: result = chain({"question": user_input}) output = f"Answer: {result['answer']}" #output = f"Answer: {result['answer']}\nSources: {result['sources']}" st.session_state.past.append(user_input) st.session_state.generated.append(output) if st.session_state["generated"]: for i in range(len(st.session_state["generated"]) - 1, -1, -1): message(st.session_state["past"], is_user=True, key=str(i) + "_user") message(st.session_state["generated"], key=str(i)) The error i get is : AttributeError: st.session_state has no attribute "past".
