Introduction

Setting up Hunyuan3D-2 locally on a Mac involves several steps, including installing necessary software, configuring the environment, and running the model. Hunyuan3D-2, developed by Tencent, is a powerful AI model that converts 2D images into 3D objects, making it a valuable tool for artists, designers, and developers. This guide provides a comprehensive walkthrough of the installation process, ensuring a smooth setup on macOS.

Prerequisites

Before proceeding with the installation, ensure that your system meets the following requirements:

  • Operating System: macOS (preferably the latest version).
  • Python: Version 3.8 or higher.
  • Homebrew: A package manager for macOS.
  • Git: For cloning repositories.
  • CUDA: If using an NVIDIA GPU (optional for CPU usage).
  • PyTorch: Required deep-learning framework.

Installing Homebrew

Homebrew simplifies software installation on macOS. To install Homebrew, open the terminal and execute:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Installing Python

Python can be installed using Homebrew:

brew install python

Verify the installation:

python3 --version

Installing Git

If Git is not installed, install it via Homebrew:

brew install git

Installing PyTorch

Visit the official PyTorch website for macOS installation instructions. You can also install it using:

pip3 install torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/cpu

For GPU support, ensure appropriate NVIDIA drivers are installed.

Cloning Hunyuan3D-2 Repository

Clone the Hunyuan3D-2 repository from GitHub:

git clone https://github.com/Tencent/Hunyuan3D-2.git

Navigate to the cloned directory:

cd Hunyuan3D-2

Setting Up the Environment

Installing Required Packages

Install all dependencies listed in requirements.txt:

pip3 install -r requirements.txt

Setting Up Texture Generation

Navigate to the texture generation directory:

cd hy3dgen/texgen/custom_rasterizer

Run the setup script:

python3 setup.py install

Running Hunyuan3D-2

Return to the main project directory:

cd ../../..

Start the application:

python3 app.py

The first run may take some time as required models are downloaded.

Using Hunyuan3D-2

Once running, Hunyuan3D-2 provides a Gradio web interface at:

http://localhost:7860

Uploading Images

  1. Click the upload button.
  2. Select a 2D image from your computer.
  3. Adjust any settings if available.
  4. Click Generate to create a 3D model.

Downloading Generated Models

After processing, download or preview your generated 3D model directly from the interface.

Troubleshooting Common Issues

Python Version Issues

Ensure Python 3.8 or higher is installed:

python3 --version

Upgrade if necessary.

Dependency Errors

If you encounter missing package errors, reinstall dependencies:

pip3 install -r requirements.txt --upgrade

Model Download Failures

If model downloads fail, check your internet connection and rerun:

python3 app.py

Conclusion

By following this guide, you can set up Hunyuan3D-2 on macOS and leverage its AI capabilities to convert 2D images into 3D models. This tool offers immense potential for applications in gaming, design, and virtual reality. Further integrations with Blender or Unity can expand its functionality for more advanced projects.
