        "description": "# gym-chrome-dino\n\nAn OpenAI Gym environment for Chrome Dino / T-Rex Runner Game\n\nThis environment utilizes \n[a forked version](https://github.com/elvisyjlin/t-rex-runner) \nof _Chrome Dino_, also called _T-Rex Runner_, \nextracted from chromium offline error page. \nSee [here](https://github.com/wayou/t-rex-runner).\n\n\n## Installation\n\nYou can install `gym-chrome-dino` from PyPI by either \n\n```bash\npip install gym-chrome-dino\n```\n\nor\n\n```bash\ngit clone https://github.com/elvisyjlin/gym-chrome-dino.git\ncd gym-chrome-dino\npip install -e .\n```\n\n\n## Usage\n\nYou can get started as follows:\n\n```python\nimport gym\nimport gym_chrome_dino\nenv = gym.make('ChromeDino-v0')\n```\n\nTo create a headless (without opening browser) environment\n\n```python\nenv = gym.make('ChromeDinoNoBrowser-v0')\n```\n\n### Observations, Actions and Rewards\n\n* The observation is a RGB numpy array with shape of (150, 600, 3).  \n* The available actions are 0: _do nothing_, 1: _jump_, and 2: _duck_.  \n* A positive reward 0.01 is given when the dinosaur is alive; a negative penalty -1.0 is given when the dinosaur hits an obstable, which might be a cactus or a bird.\n\nFor the DeepMind DQN recipe, where we give 4-stacked resized grayscaled frames (80, 160, 4) to the agent, we provide a wrapping method `make_dino()`. It also comes with a timer wrapper, which reports the interval between `env.step()`.\n\n```python\nfrom gym_chrome_dino.wrappers import make_dino\nenv = make_dino(env, timer=True, frame_stack=True)\n```\n\n### DinoGame\n\nAn instance of `DinoGame` is created when the environment is made. There are some useful methods for fine control of the training environment. The `DineGame` can be accessed as follows:\n\n```python\nenv.unwrapped.game\n```\n\n`DinoGame` provides a `get_score()` method to get the score of current game.\n\n```python\nscore = env.unwrapped.game.get_score()\n```\n\nBy default, the acceleration of the game is set to zero. If you want to restore the original acceleration value, please do `set_acceleration(True)`. On the other hand, `set_acceleration(False)` sets the value to zero.\n\n```python\nenv.unwrapped.game.set_acceleration(True)\n```\n\n\n## Example\n\nHere is a simple example to use `gym-chrome-dino`.\n\n```python\nimport gym\nimport gym_chrome_dino\nfrom gym_chrome_dino.utils.wrappers import make_dino\nenv = gym.make('ChromeDino-v0')\nenv = make_dino(env, timer=True, frame_stack=True)\ndone = True\nwhile True:\n    if done:\n        env.reset()\n    action = env.action_space.sample()\n    observation, reward, done, info = env.step(action)\n```\n\n\n## WebDriver\n\n`gym-chrome-dino` runs the game on [chromedriver](http://chromedriver.chromium.org) via `selenium` because it is a proper way to monitor and to play _Chrome Dino_. As a result, the latest chromedriver executable file will be downloaded to the current working directory where your program is.\n\n",
