我在 env 渲染中遇到错误 - env.render()

Question

我试图在渲染时实现 Atari Games，但出现如下错误：

line 283, in render
    raise error.Error(
gym.error.Error: render(mode='human') is deprecated. Please supply `render_mode` when constructing your environment, e.g., gym.make(ID, render_mode='human'). The new `render_mode` keyword argument supports DPI scaling, audio, and native framerates.

我收到的完整错误的屏幕截图附在此处。

我的代码如下：

episodes = 5

for episode in range(1, episodes+1):
state = env.reset()
done = False
score = 0 

while not done:
    env.render()
    action = random.choice([0,1,2,3,4,5])
    n_state, reward, done, info = env.step(action)
    score+=reward
print('Episode:{} Score:{}'.format(episode, score))
env.close()

---

堆栈溢出中有一个类似的帖子，其中给出的解决方案是：

pip install pyglet==1.2.4

不幸的是这对我来说也不起作用。

Answer 1

我自己已经想出来了。render_mode='human'解决方案是通过更新来更改我们正在工作的环境env：

env = gym.make('SpaceInvaders-v0', render_mode='human')

完整代码：

 import gym
 import random
 import time
 env = gym.make('SpaceInvaders-v0', render_mode='human')
 height, width, channels = env.observation_space.shape
 actions = env.action_space.n
 env.unwrapped.get_action_meanings()
 episodes = 5
 for episode in range(1, episodes+1):
    state = env.reset()
    done = False
    score = 0 
 while not done:
    time.sleep(0.1)
    action = random.choice([0,1,2,3,4,5])
    n_state, reward, done, info = env.step(action)       
    score+=reward
print('Episode:{} Score:{}'.format(episode, score))
env.close()
