### # - Author: Jaelin Lee, Abhishek Dutta # - Date: Mar 23, 2024 # - Description: Streamlit UI for mental health support chatbot using sentiment analsys, RL, BM25/ChromaDB, and LLM. # - Note: # - Updated to UI to show predicted mental health condition in behind the scence regardless of the ositive/negative sentiment ### from dotenv import load_dotenv, find_dotenv import pandas as pd import streamlit as st from q_learning_chatbot import QLearningChatbot from xgb_mental_health import MentalHealthClassifier from bm25_retreive_question import QuestionRetriever as QuestionRetriever_bm25 from Chromadb_storage_JyotiNigam import QuestionRetriever as QuestionRetriever_chromaDB from llm_response_generator import LLLResponseGenerator import os from llama_guard import moderate_chat # Streamlit UI st.title("MindfulMedia Mentor") # Define states and actions states = [ "Negative", "Moderately Negative", "Neutral", "Moderately Positive", "Positive", ] actions = ["encouragement", "empathy", "spiritual"] # Initialize Q-learning chatbot and mental health classifier chatbot = QLearningChatbot(states, actions) # Initialize MentalHealthClassifier # data_path = "/Users/jaelinlee/Documents/projects/fomo/input/data.csv" data_path = os.path.join("data", "data.csv") print(data_path) tokenizer_model_name = "nlptown/bert-base-multilingual-uncased-sentiment" mental_classifier_model_path = "mental_health_model.pkl" mental_classifier = MentalHealthClassifier(data_path, mental_classifier_model_path) # Function to display Q-table def display_q_table(q_values, states, actions): q_table_dict = {"State": states} for i, action in enumerate(actions): q_table_dict[action] = q_values[:, i] q_table_df = pd.DataFrame(q_table_dict) return q_table_df # Initialize memory if "entered_text" not in st.session_state: st.session_state.entered_text = [] if "entered_mood" not in st.session_state: st.session_state.entered_mood = [] if "messages" not in st.session_state: st.session_state.messages = [] if "user_sentiment" not in st.session_state: st.session_state.user_sentiment = "Neutral" if "mood_trend" not in st.session_state: st.session_state.mood_trend = "Unchanged" if "predicted_mental_category" not in st.session_state: st.session_state.predicted_mental_category = "" if "ai_tone" not in st.session_state: st.session_state.ai_tone = "Empathy" if "mood_trend_symbol" not in st.session_state: st.session_state.mood_trend_symbol = "" if "show_question" not in st.session_state st.session_state.show_question = False if "asked_questions" not in st.session_state: st.session_state.asked_questions = [] # Check if 'llama_guard_enabled' is already in session state, otherwise initialize it if "llama_guard_enabled" not in st.session_state: st.session_state["llama_guard_enabled"] = False # Default value to False # Select Question Retriever selected_retriever_option = st.sidebar.selectbox( "Choose Question Retriever", ("BM25", "ChromaDB") ) if selected_retriever_option == "BM25": retriever = QuestionRetriever_bm25() if selected_retriever_option == "ChromaDB": retriever = QuestionRetriever_chromaDB() for message in st.session_state.messages: with st.chat_message(message.get("role")): st.write(message.get("content")) section_visible = True # Collect user input user_message = st.chat_input("Type your message here:") # Modify the checkbox call to include a unique key parameter llama_guard_enabled = st.sidebar.checkbox( "Enable LlamaGuard", value=st.session_state["llama_guard_enabled"], key="llama_guard_toggle", ) # Update the session state based on the checkbox interaction st.session_state["llama_guard_enabled"] = llama_guard_enabled # Take user input if user_message: st.session_state.entered_text.append(user_message) st.session_state.messages.append({"role": "user", "content": user_message}) with st.chat_message("user"): st.write(user_message) is_safe = True if st.session_state["llama_guard_enabled"]: chat = [ {"role": "user", "content": user_message}, {"role": "assistant", "content": ""}, ] guard_status = moderate_chat(chat) if "unsafe" in guard_status[0]["generated_text"]: is_safe = False print("Guard status", guard_status) if is_safe == False: response = "Due to eithical and safety reasons, I can't provide the help you need.
