uv sync --frozen

Import the ROM, then play or evaluate the immutable checkpoint:

uv run rlab import-roms ~/roms --game SuperMarioBros-Nes-v0
uv run rlab play https://huggingface.co/tsilva/Level2-1_stable-baselines3-ppo_4792f358/resolve/v1/model.zip
uv run rlab eval https://huggingface.co/tsilva/Level2-1_stable-baselines3-ppo_4792f358/resolve/v1/model.zip

Evaluation

Action selection was stochastic under the published evaluation environment contract.

Limitations

Evaluation establishes performance only for the published environment hash, start distribution, policy preprocessing, and action-selection protocol. It does not establish generalization to other levels, environments, ROM revisions, or contracts.

Licensing

The rlab-authored policy weights and publication material are licensed under the MIT License in LICENSE. Emulator/runtime software and game assets remain governed by their own licenses and terms. This repository does not redistribute a game ROM.

Policy Lineage

This is a legacy rlab policy trained by Stable-Baselines3 PPO. It is not a GradLab-trained checkpoint and no GradLab compatibility is claimed.
