gymgrid2 1.2.5

No project description provided

Gymgrid

This is a fork from https://github.com/wsgdrfz/gymgrid. The original implementation does no longer work in the latest versions of gym due to the change from the pyglet renderer to pygame.

The gridworld environment contains simple environments in RL book and compatible with OpenAI-gym.

Installation

pip install gymgrid2

Usage

import gym
import gymgrid2
env = gym.make('cliff-v0')
for i_episode in range(20):
    observation = env.reset()
    for t in range(100):
        env.render()
        print(observation)
        action = env.action_space.sample()
        observation, reward, done, info = env.step(action)
        if done:
            print("Episode finished after {} timesteps".format(t+1))
            break
env.close()
print("env closed")
