Introduction to OpenAI Gym (Gymnasium): Cart-Pole Environment – Reinforcement Learning Tutorial

OpenAI Gym is an open-source toolkit for developing and comparing reinforcement learning algorithms. It provides a set of environments for testing and benchmarking different algorithms. One of the most popular environments in Gym is the Cart-Pole environment.

Cart-Pole Environment

The Cart-Pole environment consists of a pole attached to a cart, which can move along a frictionless track. The goal of the agent is to balance the pole by moving the cart left or right. The state space of the environment includes the position of the cart, the velocity of the cart, the angle of the pole, and the angular velocity of the pole. The action space consists of two actions: move left or move right.

Reinforcement Learning Tutorial

To get started with the Cart-Pole environment in OpenAI Gym, you can follow these steps:

  1. Install OpenAI Gym using the following command in your terminal:
  2. pip install gym

  3. Create an instance of the Cart-Pole environment using the following code:

  4. import gym
    env = gym.make('CartPole-v1')

  5. Reset the environment and retrieve the initial state using the reset() method:
  6. state = env.reset()

  7. Interact with the environment by taking actions using the step() method:

  8. action = env.action_space.sample()
    next_state, reward, done, info = env.step(action)

  9. Repeat steps 3 and 4 until the episode is terminated (done = True).

By following these steps, you can start experimenting with reinforcement learning algorithms in the Cart-Pole environment. OpenAI Gym provides a variety of tools and resources to help you develop and evaluate your algorithms.

Overall, the Cart-Pole environment is a simple yet challenging environment for testing reinforcement learning algorithms. It is a great starting point for beginners in the field of reinforcement learning and provides a solid foundation for building more complex algorithms in the future.

I just found out your channel. You seem to have updated and great content!

I'm doing my master thesis where I need to use RL for my work, so I appreciate your youtube videos and your website a lot. Thank you!!
