搞了一大堆还是搞不出来放弃了
最后用matplotlib画出来看
import gym
import matplotlib.pyplot as plt
from IPython import display
import numpy as np
%matplotlib inlineenv = gym.make('CartPole-v1', render_mode="rgb_array")
observation = env.reset()
a = 0
for _ in range(100):img = env.render()if img is not None:if _ % 10 ==0: # 加速动画if isinstance(img, list):img = img[0]img = np.array(img)img = img.squeeze()plt.imshow(img)display.display(plt.gcf())display.clear_output(wait=True)action = env.action_space.sample()step_result = env.step(action)env.close()
