SmolVLA Test Dataset

This is a test dataset created by the refactored SmolVLA library to demonstrate proper LeRobot format support.

Features

LeRobot v2.1 format: Fully compatible with LeRobot training pipelines
Episode structure preserved: Maintains temporal coherence
Videos included: MP4 files for visual observations
Proper metadata: Statistics, episode info, and task descriptions

Dataset Structure

.
├── data/           # Parquet files with trajectory data
├── videos/         # MP4 files for camera observations
└── meta/           # Metadata (info.json, episodes.jsonl, etc.)

Usage

from lerobot.datasets import LeRobotDataset

# Load the dataset
dataset = LeRobotDataset("SmolVLADataset/claude")

# Access samples
sample = dataset[0]
print(sample.keys())

Source

This dataset was created by merging LeRobot datasets using the SmolVLA library: https://github.com/smolvladataset/smolvladataset

The refactored library now properly:

Downloads complete LeRobot datasets with videos
Preserves episode structure and metadata
Returns LeRobot-compatible dataset objects
Validates dataset compatibility before merging
