Material

• Did you use Google Colab?
• yes

If not:

• Your Operating system (OS)
• Version of your OS
  I also tried running on my local MacOS(15.6.1), and still the last part doesn't work. package_to_hub() part.
  It submits to huggingface profile, but not to leaderboard.

Error:
✘ 'DummyVecEnv' object has no attribute 'video_recorder'
✘ We are unable to generate a replay of your agent, the package_to_hub
process continues
✘ Please open an issue at

It says here that leaderboard is no longer operational.

I'm having the same issue with 'DummyVecEnv' though
