[Bug Report] Error when calling recover_environment(): Monitor wrapper does not inherit from RecordConstructorArgs

[LorenzoBonanni]

Describe the bug
Calling recover_environment() on the 'mujoco/humanoidstandup/medium-v0' dataset raises a ValueError related to the Monitor wrapper not inheriting from gymnasium.utils.RecordConstructorArgs. This prevents the environment from being recreated.

Code example

import minari

dataset = minari.load_dataset('mujoco/humanoidstandup/medium-v0', download=True)

test_env = dataset.recover_environment()

Stack trace

ValueError: Monitor wrapper does not inherit from `gymnasium.utils.RecordConstructorArgs`, therefore, the wrapper cannot be recreated.

System Info

• Minari install method: pip install "minari[all]"
• Operating system: Ubuntu 22.04.4 LTS
• Python version: 3.12.11 (conda)
• Minari version: 0.5.3
• MuJoCo version: 3.2.3
• Gymnasium version: 1.1.1
• Pillow version: 11.2.1

Additional context
I found a workaround: before calling recover_environment(), I set dataset.env_spec.additional_wrappers = (), which avoids the error.

import minari

dataset = minari.load_dataset('mujoco/humanoidstandup/medium-v0', download=True)

# Workaround to avoid the error
dataset.env_spec.additional_wrappers = ()

test_env = dataset.recover_environment()

Ciao @LorenzoBonanni, thank you for reporting this!

Indeed, the env_spec was polluted with the Monitor wrapper of SB3.
I fixed it, so you should be able to download the dataset again and use it.
