取得" AttributeError:"ImageData"对象没有属性"data"在无头健身房jupyter Python 2.7中 [英] Getting " AttributeError: 'ImageData' object has no attribute 'data' " in headless gym jupyter Python 2.7

问题描述

我正在尝试在无头服务器中运行Gym，并在jupyter中进行渲染. Python版本2.7.

I am trying to run gym in headless server and render the same in jupyter. Python version 2.7.

我已经使用xvfb-run -a -s "-screen 0 1400x900x24" jupyter notebook

下面是我运行的Jupyte单元格.

Below is the Jupyte cell that I run.

import matplotlib.pyplot as plt
import gym
from IPython import display
%matplotlib inline

env = gym.make('CartPole-v0')
env.reset()

plt.imshow(env.render(mode='rgb_array'))
display.display(plt.gcf())    
display.clear_output(wait=True)
env.step(env.action_space.sample()) # take a random action

env.close()

但是我得到的错误如下:

But the error I get is as below :

AttributeError: 'ImageData' object has no attribute 'data'

我在论坛上进行了很多搜索，但找不到解决方案.在此先感谢您帮助我解决此错误，并让我在jupyter笔记本中渲染健身.

I have searched a lot in forums but could not find a solution. Thanks in advance to help me fix this error and make me to render gym in jupyter notebook.
