| # koch_test |
| |
| This repository contains a TsFile conversion of the original Hugging Face |
| dataset [`MoofireX/koch_test`](https://huggingface.co/datasets/MoofireX/koch_test). |
| |
| ## Source Dataset |
| |
| The source repository contains one Parquet split and LeRobot metadata files: |
| |
| ```text |
| data/train-00000-of-00001.parquet |
| meta_data/episode_data_index.safetensors |
| meta_data/info.json |
| meta_data/stats.safetensors |
| ``` |
| |
| The converted repository keeps the same top-level structure: |
| |
| ```text |
| data/train.tsfile |
| meta_data/episode_data_index.safetensors |
| meta_data/info.json |
| meta_data/stats.safetensors |
| ``` |
| |
| ## Source Schema |
| |
| The source Parquet split has 2,755 rows and 7 columns: |
| |
| | Column | Source type | Conversion | |
| |---|---|---| |
| | `observation.state` | fixed-size list float[6] | flattened to `state_0` ... `state_5` | |
| | `action` | fixed-size list float[6] | flattened to `action_0` ... `action_5` | |
| | `episode_index` | int64 | FIELD | |
| | `frame_index` | int64 | FIELD | |
| | `timestamp` | float | renamed to `episode_timestamp_s` FIELD | |
| | `next.done` | bool | renamed to `next_done` FIELD | |
| | `index` | int64 | renamed to `sample_index` FIELD | |
|
|
| ## Conversion Notes |
|
|
| - Source format converted to TsFile: lowercase `data/train-00000-of-00001.parquet`. |
| - Converted format: TsFile table model. |
| - Output file: `data/train.tsfile`. |
| - Table name: `koch_test`. |
| - TAG column: `episode_id`, synthesized from `episode_index`. |
| - Time column: synthesized from `frame_index * 100 ms`. |
| - The original `timestamp` value is preserved as `episode_timestamp_s`. |
| - `observation.state` and `action` are not dropped semantically; each 6-element |
| vector is expanded to scalar fields because TsFile import requires scalar |
| columns. |
| - Row count is preserved: 2,755 source rows -> 2,755 TsFile rows. |
|
|
| ## Metadata |
|
|
| The source `meta_data/info.json` reports: |
|
|
| ```json |
| { |
| "codebase_version": "v1.6", |
| "fps": 30, |
| "video": true, |
| "encoding": { |
| "vcodec": "libsvtav1", |
| "pix_fmt": "yuv420p", |
| "g": 2, |
| "crf": 30 |
| } |
| } |
| ``` |
|
|
| The `meta_data/` files are mirrored unchanged from the source repository for |
| traceability. The TsFile conversion only uses the Parquet split. |
