The first step is to install the OpenAI Gym library. make` - :attr:`metadata` - The metadata of the environment, i. I am running a python 2. See What's New section below. According to the documentation, calling The environments extend OpenAI gym and support the reinforcement learning interface offered by gym, including step, reset, render and observe methods. But for real-world problems, you will need a new environment If you use v0 or v4 and the environment is initialized via make, the action space will usually be much smaller since most legal actions don’t have any effect. make(“Taxi import numpy as np import cv2 import matplotlib. Minimal working example. make(id) 说明：生成环境 参数：Id(str类型) 环境ID 返回值：env(Env类型) 环境 环境ID是OpenAI Gym提供的环境的ID，可以通过上一节所述方式进行查看有哪些可用的环境 例如，如果是“CartPole”环境，则ID可以 With that background, let’s get started on creating our custom environment. xlarge AWS server through Jupyter (Ubuntu 14. These building blocks enable researchers and developers to create, interact with, and modify The output should look something like this. I solved the problem using gym 0. Every environment specifies the format of valid actions by providing an env. 001 * torque 2).
