Deep Q-learning for Playing Flappy Bird: A Guide

Feb 3, 2024 | Data Science

Welcome to the world of Reinforcement Learning! In this article, we will explore how you can train an agent to play Flappy Bird using Deep Q-learning through a simple Python script. This is a basic yet engaging example of how AI can learn through experience, much like humans do when they practice a game.

Introduction

This tutorial presents a Python source code designed to train an agent to master the game of Flappy Bird. The essence of Reinforcement Learning shines here as the agent learns to navigate the game environment through rewards and penalties.


Result of Training

How to Use My Code

Using the code is straightforward, and follows two main steps:

  • Train Your Model from Scratch: To initiate the training process, you need to run the command:
  • python train.py
  • Test Your Trained Model: After training, you can evaluate the model’s performance by executing:
  • python test.py

Trained Models

Once you have successfully trained your model, you can find it stored in the directory trained_models/flappy_bird. It’s like having a trophy at hand, ready to demonstrate your success!

Requirements

Before diving into running the code, make sure you have the following prerequisites installed:

  • Python: Version 3.6
  • Pygame: A library for creating games and multimedia experiences.
  • cv2: An Open Source Computer Vision Library.
  • PyTorch: A powerful framework for machine learning.
  • NumPy: Library for scientific computing with Python.

Understanding the Code: An Analogy

Think of training a Flappy Bird agent as teaching a young child to ride a bicycle. Initially, the child will fall over several times, learning through each crash that they must keep their balance. Just like the child, our agent will go through multiple trials in the game, each time adjusting its strategy based on whether it received a reward (successfully navigating) or a penalty (crashing into a pipe). This is how reinforcement learning operates—it’s all about learning from feedback and continuously refining strategies!

Troubleshooting

Should you encounter issues while running your code, here are a few troubleshooting ideas to consider:

  • Ensure all required libraries are installed correctly. You can install them using pip:
  • pip install pygame opencv-python torch numpy
  • If the training process doesn’t start, double-check your Python version; it should be 3.6.
  • For any persistent errors, you can check the console for more specific error messages and refer to respective documentation.
