The Space loads [`Voxel51/hard-intersection-multimodal-sample`](https://huggingface.co/datasets/Voxel51/hard-intersection-multimodal-sample) into local ephemeral storage before FiftyOne starts. The dataset is downloaded again whenever Hugging Face provisions a fresh container. This is a **grouped** dataset: each of the 4 groups is one driving episode through the Takanawadai intersection in Tokyo, Japan, with 6 synchronized camera video slices and 1 3D point cloud slice per group. Frame-level labels include COCO semantic detections, Lanelet2 HD map overlays, and the vehicle trajectory projected onto the front camera. Each browser receives a temporary clone of the dataset records while all clones share the same read-only media. Filters, modal selection, playback, tags, fields, and saved views therefore remain isolated between visitors. Inactive clones expire after 30 minutes, cleanup runs every five minutes, and the Space allows at most 20 active browser sessions. ## Use your own datasets Duplicate this Space and edit [`datasets.json`](./datasets.json) to replace or extend the dataset list. Each entry must point to a FiftyOne-formatted Hub dataset and an absolute local download path, then rebuild.
