lance-format/pusht-lerobot-lancedb
收藏资源简介:
这是一个基于Lance格式的lerobot/pusht数据集副本,采用lerobot-lancedb格式。数据集以每行一帧的方式组织,每帧的JPEG图像字节以内联方式存储,压缩质量为95。数据集包含约25,650帧,总大小约为60 MB,适用于机器人学任务,特别是推操作(PushT)场景。数据列包括episode_index、frame_index、index、timestamp、task_index、observation.state、action和observation.image(JPEG字节)。该格式支持通过字节范围从HuggingFace Hub流式加载,无需完整下载数据集。布局包括元数据文件夹和单个Lance表,适用于使用LeRobotLanceDataset库加载和处理。
This is a copy of the lerobot/pusht dataset in Lance format, adopting the lerobot-lancedb format. The dataset is organized with one frame per row, where the JPEG image bytes of each frame are stored inline at a compression quality of 95. It contains approximately 25,650 frames with a total size of roughly 60 MB, and is tailored for robotics tasks, particularly PushT manipulation scenarios. The dataset columns include episode_index, frame_index, index, timestamp, task_index, observation.state, action, and observation.image (JPEG bytes). This format supports streaming loading from the Hugging Face Hub via byte ranges, without the need to fully download the entire dataset. Its layout consists of a metadata folder and a single Lance table, and is compatible with loading and processing using the LeRobotLanceDataset library.
