LeRobot Data Studio - Unofficial LeRobot Dataset Editor

A web-based GUI for editing and merging LeRobot datasets.

Note: This is an unofficial tool and is not affiliated with Huggingface, LeRobot or the LeRobot team.

Main Features

• Merge multiple datasets into a single dataset
• Easily remove episodes and create new clean datasets
• Speed control and keyboard shortcuts to streamline dataset cleaning

Quick Start

Step 1: Prerequisites

• UV Python package and project manager: curl -LsSf https://astral.sh/uv/install.sh | sh
• Python 3.10+ (You can use uv to install and manage python versions e.g. uv python install 3.12)
• Node.js 24+ (Install using nvm - see instructions below)
• A Huggingface account (free)
• Huggingface CLI

Installing Node.js with nvm

# Install nvm (Node Version Manager)
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.3/install.sh | bash

# Reload your shell configuration
source ~/.bashrc  # or ~/.zshrc if using zsh

# Install and use Node.js 24
nvm install 24
nvm use 24

# Verify installation
node --version

Step 2: Installation

git clone https://github.com/jackvial/lerobot-data-studio
cd lerobot-data-studio

# Create a virtual environment with UV
uv venv

# Activate the virtual environment
source .venv/bin/activate

# Install all packages using UV
uv sync

Step 3: Install Frontend Dependencies

After completing the python installation, install frontend dependencies:

cd packages/lerobot-data-studio/frontend
npm install

Step 4: Running the App

Use the provided script to start both frontend and backend servers:

./run_dev.sh

Dataset Creation

Dataset creation for merged and filtered (AKA edited) datasets is always none destructive and will always create a new dataset and upload it to the Huggingface Hub.

Merged Dataset Creation

Merges multiple datasets into a single new dataset and uploads it to the Huggingface Hub.

Filtered Dataset Creation

Editing/filtering a dataset creates a new dataset that only excludes the episodes that were selected in the UI.

Development

Run Backend Tests

uv run pytest

Run Frontend Tests

cd src/lerobot_data_studio/frontend
npm run test
