**[Project Page](https://multi-graspllm.github.io/)** | **[arXiv](https://arxiv.org/abs/2412.08468)**

---
## Updates
- **2025.3**: We add the Jaco hand data which is our final version.
- **2025.1**: We add the Barrett hand data.
- **2024.12**: Released the Multi-GraspSet dataset with meshes of objects.
- **2024.12**: Released the Multi-GraspSet dataset with contact annotations.

## Overview

We introduce **Multi-GraspSet**, the first large-scale multi-hand grasp dataset enriched with automatic contact annotations.

## Installation

Follow these steps to set up the evaluation environment:

1. **Create the Environment**
    ```bash
    conda create --name eval python=3.9
    ```

2. **Install PyTorch and Dependencies**
    ```bash
    pip install torch==2.0.1 torchvision==0.15.2 torchaudio==2.0.2
    ```
    > ⚠️ Ensure the CUDA toolkit version matches your installed PyTorch version.

3. **Install Pytorch Kinematics**
    ```bash
    cd ./pytorch_kinematics
    pip install -e .
    ```

4. **Install Remaining Requirements**
    ```bash
    pip install -r requirements_eval.txt
    ```
