AttributeError: module 'faiss' has no attribute 'read_index'

Hi all,

I used the FAISS library to create a persisted vector db of the documents i’d like my model to answer questions on.

I created a custom function load_vectordb to load the vectordb that I have saved in my github repo.

jemyap91/LLM-for-good/blob/main/app3.py

import os
import tempfile
import requests
import streamlit as st
from langchain.chat_models import ChatOpenAI
from langchain.document_loaders import PyPDFLoader
from langchain.memory import ConversationBufferMemory
from langchain.memory.chat_message_histories import StreamlitChatMessageHistory
from langchain.embeddings import HuggingFaceEmbeddings
from langchain.callbacks.base import BaseCallbackHandler
from langchain.chains import ConversationalRetrievalChain
from langchain.vectorstores import DocArrayInMemorySearch
from langchain.text_splitter import RecursiveCharacterTextSplitter
from langchain.vectorstores import Chroma, FAISS
from langchain.embeddings.openai import OpenAIEmbeddings


st.set_page_config(page_title="LangChain: Chat with Eric the E-Teacher", page_icon="🤓")
st.title("🤓 Chat with Eric the Econs E-Teacher about Economics!")

This file has been truncated. show original

However, it has been returning an AttributeError: module ‘faiss’ has no attribute ‘read_index’.

The full error log can be found here:

Would appreciate advice on this please! Many thanks.

faiss-cpu==1.7.4

Use the following version of FAISS in the requirements.txt file
