  5. Knowledge Assortment and Evaluation: Chatbots could collect helpful info from person interactions, giving firms an understanding of consumer preferences, needs, and ache spots. Utilizing this knowledge, enhance the services.

Let’s go on to the step-by-step breakdown of the code wanted to construct a bespoke chatbot utilizing OpenAI now that we’re conscious of some great benefits of chatbots.

Steps

Step 1: Importing the Required Libraries

We have to import the mandatory libraries. Within the offered code, we will see the next import statements:


!pip set up langchain
!pip set up faiss-cpu
!pip set up openai
!pip set up llama_index

# or you need to use

%pip set up langchain
%pip set up faiss-cpu
%pip set up openai
%pip set up llama_index

Be sure you have these libraries put in earlier than shifting on.

Step 2: Setting Up the API Key

To work together with the OpenAI API, you want an API key. Within the offered code, there’s a placeholder indicating the place so as to add your API key:

To seek out you API Key, go to openai web site and create a brand new open ai key.

import os 
os.environ["OPENAI_API_KEY"] = 'Add your API Key right here'

Change ‘Add your API Key right here’ along with your precise API key obtained from OpenAI.

Step 3: Creating and Indexing the Information Base

On this step, we’ll create and index the information base that the chatbot will discuss with for answering person queries. The offered code demonstrates two approaches: one for loading paperwork from a listing and one other for loading an present index. Let’s deal with the primary strategy.


from llama_index import GPTVectorStoreIndex, SimpleDirectoryReader
paperwork = SimpleDirectoryReader('/Customers/tarakram/Paperwork/Chatbot/knowledge').load_data()
print(paperwork)

Use the SimpleDirectoryReader class to load the paperwork from a particular listing.

Change ‘/Customers/tarakram/Paperwork/Chatbot/knowledge’ with the trail to your listing containing the information base paperwork. The load_data() operate masses the paperwork and returns them.

After loading the paperwork, we have to create an index utilizing the GPTVectorStoreIndex class:

index = GPTVectorStoreIndex.from_documents(paperwork)

This step creates the index utilizing the loaded paperwork.

Step 4: Persisting the Index

To keep away from the necessity for rebuilding the index each time the code runs, we will persist the index to disk. Within the offered code, the next line is used to save lots of the index:


# Save the index
index.storage_context.persist('/Customers/tarakram/Paperwork/Chatbot')

Make certain to switch ‘/Customers/tarakram/Paperwork/Chatbot’ with the specified listing path the place you need to save the index.

By persisting the index, we will load it in subsequent runs with out incurring extra token prices.

Step 5: Loading the Index

In case you need to load the beforehand saved index, you need to use the next code:

from llama_index import StorageContext, load_index_from_storage

# rebuild storage context
storage_context = StorageContext.from_defaults
                  (persist_dir="/Customers/tarakram/Paperwork/Chatbot/index")
# load index
index = load_index_from_storage(storage_context)

Make sure that you replace ‘/Customers/tarakram/Paperwork/Chatbot/index’ with the proper listing path the place you save the index.

Step 6: Creating the Chatbot Class

Now, let’s transfer on to creating the precise chatbot class that interacts with the person and generates responses. Right here’s the offered code:

# Chat Bot

import openai
import json

class Chatbot:
    def __init__(self, api_key, index):
        self.index = index
        openai.api_key = api_key
        self.chat_history = []

    def generate_response(self, user_input):
        immediate = "n".be a part of([f"{message['role']}: {message['content']}" 
                           for message in self.chat_history[-5:]])
        immediate += f"nUser: {user_input}"
        query_engine = index.as_query_engine()
        response = query_engine.question(user_input)

        message = {"position": "assistant", "content material": response.response}
        self.chat_history.append({"position": "person", "content material": user_input})
        self.chat_history.append(message)
        return message

    def load_chat_history(self, filename):
        attempt:
            with open(filename, 'r') as f:
                self.chat_history = json.load(f)
        besides FileNotFoundError:
            move

    def save_chat_history(self, filename):
        with open(filename, 'w') as f:
            json.dump(self.chat_history, f)

The Chatbot class has an __init__ technique to initialize the chatbot occasion with the offered API key and index.

The generate_response technique takes person enter, generates a response utilizing the index and OpenAI API, and updates the chat historical past.

The load_chat_history and save_chat_history strategies are used to load and save the chat historical past, respectively.

Step 7: Interacting with the Chatbot

The ultimate step is to work together with the chatbot. Right here’s the offered code snippet that demonstrates find out how to use the chatbot:


bot = Chatbot("Add your API Key right here ", index=index)
bot.load_chat_history("chat_history.json")

whereas True:
    user_input = enter("You: ")
    if user_input.decrease() in ["bye", "goodbye"]:
        print("Bot: Goodbye!")
        bot.save_chat_history("chat_history.json")
        break
    response = bot.generate_response(user_input)
    print(f"Bot: {response['content']}")

To make use of the chatbot, create an occasion of the Chatbot class by passing your OpenAI API key and the loaded index.

Change “Add your API Key right here ” along with your precise API key. The load_chat_history technique is used to load the chat historical past from a file (change “chat_history.json” with the precise file path).

Then, some time loop is used to repeatedly get person enter and generate responses till the person enters “bye” or “goodbye.”

The save_chat_history technique is used to save lots of the chat historical past to a file.

import json
import os

from llama_index import StorageContext, load_index_from_storage

os.environ["OPENAI_API_KEY"] = 'Add your API Key right here '

# rebuild storage context
storage_context = StorageContext.from_defaults
                 (persist_dir="/Customers/tarakram/Paperwork/Chatbot/index")
# load index
index = load_index_from_storage(storage_context)

# Create the chatbot
# Chat Bot 

import openai
import json

class Chatbot:
    def __init__(self, api_key, index, user_id):
        self.index = index

        self.chat_history = []
        self.filename = f"{self.user_id}_chat_history.json"

    def generate_response(self, user_input):
        immediate = "n".be a part of([f"{message['role']}: {message['content']}" 
                           for message in self.chat_history[-5:]])
        immediate += f"nUser: {user_input}"
        query_engine = index.as_query_engine()
        response = query_engine.question(user_input)

        message = {"position": "assistant", "content material": response.response}
        self.chat_history.append({"position": "person", "content material": user_input})
        self.chat_history.append(message)
        return message
    
    def load_chat_history(self):
        attempt:
            with open(self.filename, 'r') as f:
                self.chat_history = json.load(f)
        besides FileNotFoundError:
            move

    def save_chat_history(self):
        with open(self.filename, 'w') as f:
            json.dump(self.chat_history, f)
            
# Streamlit app

        bot = Chatbot("Add your API Key right here ", index, user_id)

        # Load chat historical past
        bot.load_chat_history()

        # Show chat historical past
        for message in bot.chat_history[-6:]:
            st.write(f"{message['role']}: {message['content']}")

        # Consumer enter
        user_input = st.text_input("Sort your questions right here :) - ")

        # Generate response
        if user_input:
            if user_input.decrease() in ["bye", "goodbye"]:
                bot_response = "Goodbye!"
            else:
                bot_response = bot.generate_response(user_input)
                bot_response_content = bot_response['content']
                st.write(f"{user_id}: {user_input}")
                st.write(f"Bot: {bot_response_content}")
                bot.save_chat_history()
                bot.chat_history.append 
                         ({"position": "person", "content material": user_input})
                bot.chat_history.append
                       ({"position": "assistant", "content material": bot_response_content})
