Prerequisites

To complete this tutorial, you’ll need:

• Python 3.x installed on your computer
• The PyQt or PySide package installed on your computer

Step 1: Install PyQt or PySide

To install PyQt or PySide, you can use pip, the Python package manager. Open a terminal or command prompt and run one of the following commands:

For PyQt:

Copy codepip install pyqt5

For PySide:

Copy codepip install pyside2

Step 2: Set up the project

Create a new Python file named main.py in a directory of your choice. Open the file in your favorite code editor.

In this example, we will use the OpenAI API to generate a greeting message using GPT-3. To use the API, you’ll need an API key. If you don’t have one already, you can sign up for one on the OpenAI website.

Add the following code to the top of your main.py file to import the necessary modules:

pythonCopy codeimport openai
from PySide2 import QtWidgets

Next, add the following code to set up the OpenAI API:

pythonCopy codeopenai.api_key = "YOUR_API_KEY_HERE"
model_engine = "davinci" # We'll use the "davinci" engine for this example

Step 3: Create the GUI

Add the following code to create a simple GUI with a button:

pythonCopy codeclass HelloWorld(QtWidgets.QWidget):
    def __init__(self):
        super().__init__()

        self.button = QtWidgets.QPushButton("Generate Greeting")
        self.button.clicked.connect(self.generate_greeting)

        layout = QtWidgets.QVBoxLayout()
        layout.addWidget(self.button)

        self.setLayout(layout)

    def generate_greeting(self):
        # Add code to generate greeting here
        pass


app = QtWidgets.QApplication([])
window = HelloWorld()
window.show()
app.exec_()

This will create a simple window with a button labeled “Generate Greeting”. When the button is clicked, the generate_greeting method will be called.

Step 4: Add code to generate a greeting

Add the following code to the generate_greeting method to generate a greeting using the OpenAI API:

pythonCopy codedef generate_greeting(self):
    prompt = "Say hello to the world"
    response = openai.Completion.create(
        engine=model_engine,
        prompt=prompt,
        max_tokens=50
    )
    greeting = response.choices[0].text.strip()
    QtWidgets.QMessageBox.information(self, "Greeting", greeting)

This will generate a greeting using the OpenAI API and display it in a message box.

Step 5: Run the app

Save the main.py file and run it using Python:

cssCopy codepython main.py

This should launch the GUI window. Click the “Generate Greeting” button to generate a greeting using GPT-3.

Congratulations, you’ve created a “Hello World” ChatGPT Python + PyQt/PySide app
