In this guide, we will walk through the process of creating a Deep Convolutional Neural Network (DCNN) that learns to play the Google Chrome offline game, Dino Run, using a model-less Reinforcement Learning algorithm. This article will provide you with a step-by-step approach to setting up the environment, installing necessary dependencies, and troubleshooting common issues.

Step 1: Cloning the Repository

The first step in our journey is to clone the repository that contains the necessary code for the tutorial. You can do this by running the following command:

$ git clone https://github.com/Paperspace/DinoRunTutorial.git

Step 2: Initializing the File System

Once you have cloned the repository, you need to initialize the file system to save your progress and be able to resume from where you left off. To do this, invoke the following function for the first time:

init_cache()

Step 3: Installing Dependencies

To ensure that everything runs smoothly, you will need to install several dependencies. This can be done using either pip or conda for your Anaconda environment. The key libraries required are:

• Python 3.6
• ML libraries (numpy, pandas, keras, tensorflow, etc.)
• Selenium
• OpenCV

Run the following command to install all necessary dependencies:

pip install -r requirements.txt

Step 4: Setting Up ChromeDriver

In order to automate the interaction with the Dino Run game, you will need to install ChromeDriver. Follow these steps:

1. Navigate to ChromeDriver Downloads.
2. Download the version that matches your Chrome installation. You can find your version by navigating to Chrome settings and clicking on “About Chrome.”
3. Change the path of ChromeDriver accordingly in the Reinforcement Learning Dino Run.ipynb file (Default = ..chromedriver).

Understanding the Code with an Analogy

Think of the Deep Convolutional Neural Network (DCNN) as a young child learning to navigate a maze. The child (the DCNN) has a set of senses (visual input) and must follow certain paths (action patterns) to reach the end of the maze (winning the game). At first, the child may take random paths and hit dead ends (wrong actions). However, with each attempt, the child starts to memorize which paths lead to success (reinforcement learning). Over time, the child becomes adept at finding the quickest routes (effective actions), ultimately mastering the maze and winning the game with ease.

Troubleshooting Common Issues

If you encounter any problems while setting up or running the code, here are some troubleshooting ideas to help you out:

• Make sure that all dependencies are installed correctly. If you face issues, try re-installing them or check for version conflicts.
• Ensure that ChromeDriver is compatible with your Chrome version. Also, confirm that the path in your code is set correctly.
• If the game does not start, make sure that permissions are granted for ChromeDriver to run the game.
