| # record-test_3 TsFile |
| |
| This dataset is a TsFile conversion of the LeRobot dataset |
| [`sunparticle/record-test_3`](https://huggingface.co/datasets/sunparticle/record-test_3). |
| The source dataset was created with [LeRobot](https://github.com/huggingface/lerobot) |
| and is licensed under `apache-2.0`. |
| |
| ## Dataset Details |
| |
| - Source dataset: [`sunparticle/record-test_3`](https://huggingface.co/datasets/sunparticle/record-test_3) |
| - Source format: LeRobot `v2.1` |
| - Robot type: `so101_follower` |
| - Modalities: Time-series robot state and action data |
| - Source task: `place crown on capybara` |
| - Split: `train` |
| - Episodes: `40` |
| - Frames / rows: `17403` |
| - Tasks: `1` |
| - Sampling rate: `30 fps` |
| - Source videos: `40` |
| - Converted data file: `data/record_test_3_train.tsfile` |
|
|
| ## TsFile Layout |
|
|
| The conversion writes one TsFile table for the train split: |
| `record_test_3_train`. |
|
|
| - `Time` is the TsFile time column in milliseconds. |
| - `episode_index` and `task_index` are TAG columns. |
| - `frame_index` and `sample_index` are scalar FIELD columns. |
| - `action_0` through `action_5` are flattened action FIELD columns. |
| - `observation_state_0` through `observation_state_5` are flattened observation FIELD columns. |
|
|
| Vector column flattening preserves the source column name, replaces `.` with |
| `_`, and appends the element index. For example, `observation.state` becomes |
| `observation_state_0` through `observation_state_5`. |
|
|
| ## Conversion Notes |
|
|
| - `Time = round(timestamp * 1000)` and restarts per episode. |
| - The source `timestamp` column is dropped because it is represented by `Time / 1000` seconds. |
| - The source `index` column is renamed to `sample_index`. |
| - No numeric time-series rows are dropped; the converted TsFile has `17403` rows. |
| - Source `meta/` files are mirrored, with `meta/info.json` updated to describe the converted TsFile artifact. |
| - Videos are not uploaded here. The source video feature `observation.images.front` |
| and the `videos/` tree remain in the original dataset: |
| <https://huggingface.co/datasets/sunparticle/record-test_3/tree/main/videos>. |
|
|
| ## Read Example |
|
|
| Use the Apache TsFile SDK or TsFile tools to read: |
|
|
| ```text |
| data/record_test_3_train.tsfile |
| ``` |
|
|
| For episode-level filtering, query the table with the TAG column, for example |
| `WHERE episode_index = 0`. |
