When running the code

#@title test virtual display

#@markdown If you see a video of a four-legged ant fumbling about, setup is complete!

import gym
from cs285.infrastructure.colab_utils import (
    wrap_env,
    show_video
)

env = wrap_env(gym.make("Ant-v4", render_mode='rgb_array'))

observation = env.reset()
for i in range(100):
    env.render()
    obs, rew, term, _ = env.step(env.action_space.sample() )
    if term:
      break;

env.close()
print('Loading video...')
show_video()

It shows:

Wish to know whether the code still can run on the colab
