+# pusht-lerobot-lancedb (frames / JPEG)
+
+A [`lerobot-lancedb`](https://github.com/lancedb/lerobot-lancedb)-format Lance copy of
+[`lerobot/pusht`](https://huggingface.co/datasets/lerobot/pusht). One row per frame; per-frame
+JPEG bytes stored inline.
+
+> **Not to be confused with** [`lance-format/lerobot-pusht-lance`](https://huggingface.co/datasets/lance-format/lerobot-pusht-lance),
+> which uses a different three-table schema (`frames`/`episodes`/`videos`) and is **not loadable**
+> with `lerobot-lancedb`. This repo is specifically the layout produced by
+> `lerobot-convert-to-lance`.
+
+## Load
+
+```python
+from lerobot_lancedb import LeRobotLanceDataset
+
+ds = LeRobotLanceDataset(repo_id="lance-format/pusht-lerobot-lancedb")
+print(len(ds))                 # 25_650 frames
+print(ds[0]["observation.image"].shape)  # torch.Size([3, 96, 96])
+```
+
+Lance streams per-frame bytes via byte-range fetches from the Hub — no full-dataset download.
+
+## Repro
+
+```bash
+pip install git+https://github.com/lancedb/lerobot-lancedb.git
+lerobot-convert-to-lance \
+    --repo-id=lerobot/pusht \
+    --output=./pusht-lerobot-lancedb \
+    --table-name=pusht-lerobot-lancedb \
+    --jpeg-quality=95
+```
