Building a Product Information Retrieval System with ChatGPT, Flask, and PyQt6

 Introduction:

In this article, we will explore how to train ChatGPT, a powerful language model, to retrieve specific product information. We will build a web API using Flask and create a user interface using PyQt6. Users will be able to enter questions about a product, and ChatGPT will generate responses with relevant product information.

Section 1: Setting up the Flask API

1. Install Flask and set up a new Flask project.
2. Define the necessary routes for handling API requests, such as /retrieve_info for retrieving product information.
3. Implement the logic for processing user questions and generating responses using ChatGPT.
4. Integrate the ChatGPT model into the Flask API by calling the model and generating responses based on user input.

Section 2: Creating the PyQt6 User Interface

1. Install PyQt6 and set up a new PyQt6 project.
2. Design the user interface using the appropriate PyQt6 widgets, including a QLineEdit for entering questions, a QPushButton to execute the question, and a QTextEdit to display the conversation history.
3. Connect the button's click event to a function that sends the user's question to the Flask API and updates the QTextEdit with the response from ChatGPT.
4. Implement error handling and display appropriate messages to the user in case of API failures or other issues.

Section 3: Running the Application

1. Launch the Flask API using a development server.
2. Start the PyQt6 application and display the user interface to the user.
3. Allow the user to enter questions and interact with ChatGPT to retrieve product information.
4. Continuously update the QTextEdit widget with the conversation history, including the user's questions and ChatGPT's responses.

Conclusion:

By combining the power of ChatGPT, Flask, and PyQt6, we have built a robust system for retrieving specific product information. Users can now enter questions through the PyQt6 user interface, and ChatGPT will generate informative responses based on the product data. This system can be further enhanced with more training data and improved user experience features.

Additional Considerations:

• It's important to handle security and authentication measures when deploying the Flask API to protect sensitive product information.
• Training the ChatGPT model specifically for product information retrieval may require a dataset containing relevant product details and associated questions.
• Implementing data caching or other optimization techniques can improve the response time of the API and enhance the user experience.

By following the steps outlined in this article, you'll be able to develop a product information retrieval system using ChatGPT, Flask, and PyQt6. Users can interact with the system through the PyQt6 user interface, and ChatGPT will provide accurate and helpful product information based on their queries.

Here is an example of a Python-Flask Program:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36

from flask import Flask, jsonify, request app = Flask(__name__) # Sample product data products = [ { 'id': 1, 'name': 'Product 1', 'description': 'Description of Product 1', 'price': 10.99 }, { 'id': 2, 'name': 'Product 2', 'description': 'Description of Product 2', 'price': 19.99 } ] # Endpoint to retrieve all products @app.route('/products', methods=['GET']) def get_all_products(): return jsonify(products) # Endpoint to retrieve a specific product by ID @app.route('/products/<int:product_id>', methods=['GET']) def get_product_by_id(product_id): product = next((product for product in products if product['id'] == product_id), None) if product: return jsonify(product) else: return jsonify({'message': 'Product not found'}), 404 if __name__ == '__main__': app.run(debug=True)

In this example, we define two endpoints: /products to retrieve all products and /products/{id} to retrieve a specific product by ID. We use a simple list of dictionaries to store the product data.

To run the example, save the code in a file (e.g., app.py) and execute it using Python. The API will be available at http://localhost:5000. You can access the endpoints using tools like curl or Postman.

Here are a few example requests you can make:

• GET http://localhost:5000/products: Retrieves all products.
• GET http://localhost:5000/products/1: Retrieves the product with ID 1.
• GET http://localhost:5000/products/3: Returns a "Product not found" message as there is no product with ID 3.

Feel free to modify the code according to your specific requirements and integrate it with your trading platform's existing infrastructure.

And Lastly, here is the Python-Pyqt6 program:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73

import sys from PyQt6.QtWidgets import QApplication, QWidget, QVBoxLayout, QLabel, QLineEdit, QTextEdit, QPushButton from PyQt6.QtGui import QTextCursor import requests class ChatGPTApp(QWidget): def __init__(self): super().__init__() self.setWindowTitle('ChatGPT Product Information') self.setGeometry(100, 100, 400, 400) self.question_label = QLabel('Enter your question:') self.question_input = QLineEdit() self.chatlog_label = QLabel('Chat Log:') self.chatlog_output = QTextEdit() self.chatlog_output.setReadOnly(True) self.ask_button = QPushButton('Ask') self.ask_button.clicked.connect(self.process_question) layout = QVBoxLayout() layout.addWidget(self.question_label) layout.addWidget(self.question_input) layout.addWidget(self.ask_button) layout.addWidget(self.chatlog_label) layout.addWidget(self.chatlog_output) self.setLayout(layout) self.base_url = 'http://127.0.0.1:5000/products' def process_question(self): question = self.question_input.text() if question: product_id = self.extract_product_code(question) if product_id: response = self.get_product_info(product_id) if 'message' in response: answer = response['message'] else: print(response) answer = response['description'] else: answer = 'Invalid question format. Please enter a valid product code.' self.update_chatlog(question, answer) self.question_input.clear() def extract_product_code(self, question): # Extract numeric product code from the question product_code = ''.join(filter(str.isdigit, question)) if product_code: return product_code return None def get_product_info(self, product_id): url = f'{self.base_url}/{product_id}' response = requests.get(url) if response.status_code == 200: return response.json() elif response.status_code == 404: return {'message': 'Product not found'} else: return {'message': 'Error occurred'} def update_chatlog(self, question, answer): log = f'User: {question}\nChatGPT: {answer}\n\n' self.chatlog_output.insertPlainText(log) self.chatlog_output.moveCursor(QTextCursor.MoveOperation.End) if __name__ == '__main__': app = QApplication(sys.argv) chatgpt_app = ChatGPTApp() chatgpt_app.show() sys.exit(app.exec())

To run this program, make sure you replace 'YOUR_OPENAI_API_KEY' with your actual OpenAI API key. Save the program in a Python file, for example, chatgpt_product_info.py, and execute it. You will see a PyQt6 window with an input field to enter questions, a "Ask" button to send the question to ChatGPT, and a chat log area to display the conversation history between the user and ChatGPT.

The program only answers the question "What is the description or product 1?", Feel free to modify the program to return the price, etc. Also it only detects numeric numbers in the question, so it is not really that intelligent, you need to create a Machine Learning Model to identify intelligently the product id in the question. But in this example, users are like having conversation with a human.

Note: The Python Codes in this article is generated by ChatGPT and I have yet to verify if the program is working. But do note that it is very useful already and it is meant to give an idea on how to create the program
