LSY-lab Libero+ Goal Noise All Sawyer Failures (TsFile)
This repository contains the numeric time-series portion of the LSY-lab/libero_plus_goal_noise_all_sawyer_failures dataset converted from LeRobot Parquet to Apache TsFile. The source dataset was created with LeRobot and describes Sawyer robot demonstrations collected for the Libero+ goal-noise failure setting.
Source and attribution
- Publisher: Learning Systems Lab (LSY-lab)
- Hugging Face contributor shown in the file history: max-chr
- License: Apache-2.0
- Source dataset: https://huggingface.co/datasets/LSY-lab/libero_plus_goal_noise_all_sawyer_failures
- Source format: data/chunk-{chunk_index:03d}/file-{file_index:03d}.parquet
- Sampling rate: 20 FPS
- Scale: 194 episodes, 8 tasks, 42,456 frames (one train split)
TsFile contents
The converted file is data/libero_plus_goal_noise_all_sawyer_failures.tsfile (one merged table with 42,456 rows). Each episode_index + task_index pair is a TsFile table TAG/device identity; Time restarts at zero for each episode and is round(timestamp * 1000) in milliseconds.
| Role | Columns |
|---|---|
| Time | Time (INT64, milliseconds) |
| TAG/device | episode_index, task_index (INT64 source identifiers) |
| Integer FIELD | frame_index, sample_index (INT64) |
| FLOAT FIELD | Flattened state/action columns listed below |
Vector columns retain their full source name (with dots replaced by underscores) and append an element index:
- observation.state -> observation_state_0 ... observation_state_7
- observation.states.ee_state -> observation_states_ee_state_0 ... _5
- observation.states.joint_state -> observation_states_joint_state_0 ... _6
- observation.states.gripper_state -> observation_states_gripper_state_0 ... _1
- action -> action_0 ... action_6
The source timestamp column is intentionally dropped because it is represented by Time; index is retained as sample_index. No source rows are dropped. Video feature columns are omitted from TsFile because TsFile stores the numeric table only.
Encoding and size
The converter uses the compact profile requested for this dataset: FLOAT fields use GORILLA encoding, INT32/INT64 and Time use TS_2DIFF, and physical columns use LZ4 compression. TAGs are stored through the TsFile table/device mechanism. The resulting TsFile is approximately 5.26 MB versus the 7.74 MB source Parquet frame file.
Video location and alignment
Videos remain in the original Hugging Face repository and are not copied here. They are stored under https://huggingface.co/datasets/LSY-lab/libero_plus_goal_noise_all_sawyer_failures/tree/main/videos with the pattern videos/{video_key}/chunk-{chunk_index:03d}/file-{file_index:03d}.mp4. Available video keys are observation.images.frontview_image, observation.images.image, observation.images.sideview_image, and observation.images.wrist_image. Video frames align to numeric rows by episode/frame index at 20 FPS.
Reading the TsFile
Use the Apache TsFile SDK or a compatible table reader. For example, with the Python TsFile SDK:
from tsfile import TsFileReader
reader = TsFileReader('data/libero_plus_goal_noise_all_sawyer_failures.tsfile')
# Query/filter with the table reader API; episode_index and task_index are TAGs.
The mirrored meta/info.json records the source metadata and a tsfile_conversion object with the exact mapping, flattened features, row count, and original video policy.
