# SceneData-N1

<!-- 
## 🔑 Key Features

- **Unified Format for Different Benchmarks**
  
  InternData-N1 consolidates three subsets—VLN-CE, VLN-PE, and VLN-N1—into the mainstream LeRobot (v2.1) format, facilitating convenient usage across different systems and diverse benchmarks.

- **Diverse Data Covering Different Embodiments, Tasks, and Scenes**

  InternData-N1 offers diversity through its foundation of 3,000+ scene assets, extensive randomization across different robot embodiments and viewpoints, and rephrased instructions generated by LLMs for common navigation tasks.

- **High Quality Through Effective Generation and Filtering**

  InternData-N1 ensures high quality by employing effective data generation strategies (producing smooth and safe trajectories) and rigorous filtering (excluding samples with very few reference objects). This results in state-of-the-art performance for models trained on it, such as InternVLA-N1.

## 📅 TODO List

- [x] **InternData-N1 subsets**: 2.8k+ VLN-PE, 150k+ VLN-CE, 6k+ VLN-N1 episodes
- [ ] **Release 200k+ VLN-N1** (in 2 weeks)
- [ ] **VLN-CE v1 -> v1.3** (in one month)

## 🔥 Get Started

### Download the Dataset

To download the full dataset, you can use the following commands. If you encounter any issues, please refer to the official Hugging Face documentation.

```bash
# Make sure you have git-lfs installed (https://git-lfs.com)
git lfs install

# When prompted for a password, use an access token with read permissions.
# Generate one from your settings: https://huggingface.co/settings/tokens
git clone https://huggingface.co/datasets/InternRobotics/InternData-N1

# If you want to clone without large files - just their pointers
GIT_LFS_SKIP_SMUDGE=1 git clone https://huggingface.co/datasets/InternRobotics/InternData-N1

-   `scene_data/mp3d_pe/`: Improved Matterport3D scene assets for VLN-PE benchmark.
-   `scene_data/mp3d_n1/`: Base Matterport3D scans used for generating VLN-N1 trajectory data.
-   `scene_data/mp3d_ce/`: Matterport3D scene assets for VLN-CE benchmark.
-   `scene_data/n1_eval_scenes/`: Scene assets for VLN-N1 benchmark.
-   `scene_data/gradio_scene_assets/`: Selection of MP3D_CE scenes (with ceilings removed) for rapid interactive testing of the [InternVLA-N1](https://huggingface.co/InternRobotics/InternVLA-N1) model. These simplified environments allow users to quickly verify model performance in key scenarios.
