I want a SceneLoader library class for loading NAVSIM/OpenScene log pickle data into scene objects.

I want a SceneLoader library class for loading NAVSIM/OpenScene log pickle data into scene objects.: a task in MiMo-V2.6-RL-harbor-code: MiMo-V2.6-RL Code (Harbor) (Harbor dataset). The loader should expose tokens: list str , num future frames: int , num history frames: int , len () - int …

The task

The loader should expose `tokens: list[str]`, `num_future_frames: int`, `num_history_frames: int`, `__len__() -> int`, `__getitem__(idx) -> str`, `get_scene_from_token(token: str) -> Scene`, `get_agent_input_from_token(token: str) -> AgentInput`, and `get_tokens_list_per_log() -> dict[str, list[str]]`. If `data_path`…
