Gym 1.0, according to the developers' roadmap, will introduce a number of breaking changes and deprecations that will necessitate appropriate changes to colabgymrender. The ones of concern are mainly:

• Updated render API requires render mode to be provided at environment initialization, rather than on step()
• Updated step API will soon return 5 outputs, that is, observation, reward, terminal, truncation, info
• Updated reset will always return info now, in addition to observation

As of right now, the plan for colabgymrender is to play along with these new changes by incrementing the major version of this package to avoid any strange surprises. We'll probably introduce colabgymrender==2.0.0 around the same time gym introduces its first major version.

UPDATE (10/02/22)

I have created a new branch gym-1.0. All pull requests targeted at resolving recent breaking changes in gym will be referred to this branch. Once gym version 1.0 is released, this branch will be merged with the base. See #8 and #9.

Feel free to discuss your opinion on this roadmap below. #

When I attempt to record an environment, it only records 1 second worth of video. What am I doing wrong?

import gym

env = gym.make("LunarLander-v2")
env.action_space.seed(42)

env = Recorder(env, './video')

observatio = env.reset()

# img = plt.imshow(env.render('rgb_array'))

observation = env.reset()
for _ in range(10000):
  # img.set_data(env.render('rgb_array'))
  # display.display(plt.gcf())
  # display.clear_output(wait=True)
  observation, reward, done, info = env.step(env.action_space.sample())

  if done:
      observation = env.reset()

env.release()
env.play()
env.close()

Legacy gym has migrated to Gymnasium. This package is not compatible.

in recording.py you use progress_bar argument which is deprecated from new versions of moviepy, now you should use logger ='bar' for
progress_bar=True and logger=None for False

Hey !

Thanks for this tool ! Actually I tried running it but keep getting the same error:

TypeError                                 Traceback (most recent call last)

     70         filename = 'temp-{start}.mp4'
     71         clip = VideoFileClip(self.path)
---> 72         clip.write_videofile(filename, progress_bar = False, verbose = False)
     73         display(Video(filename, embed = True))
     74         os.remove(filename)

TypeError: write_videofile() got an unexpected keyword argument 'progress_bar'

I guess it's related to the moviepy library and that I don't have the right version thus could you specify which version is required ?

I followed the instructions and tutorial for Google colab and after my imports I get this error when running the wrapper?
