-# 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.
-## Citation
-Please cite the original dataset:
-```bibtex

-  author = {MoofireX},
-  title = {koch_test},
-  publisher = {Hugging Face},
