git clone https://github.com/tencent/Hunyuan3D-2
cd Hunyuan3D-2

2. Install Requirements

pip install -r requirements.txt

3. Install HunYuan3D

python setup.py install

4. Verify Installation

python -c "import hunyuan3d; print(hunyuan3d.__version__)"

Post-Installation Configuration

1. Environment Variables

# Linux/macOS
export HUNYUAN3D_HOME=/path/to/hunyuan3d
export CUDA_VISIBLE_DEVICES=0

# Windows
set HUNYUAN3D_HOME=C:\path\to\hunyuan3d
set CUDA_VISIBLE_DEVICES=0

2. Model Downloads

# Download pre-trained models
python -m hunyuan3d.utils.download_models

3. Configuration File Setup

# config.yaml
model:
  type: "standard"
  precision: "float16"
  cache_dir: "./model_cache"

system:
  gpu_memory_fraction: 0.8
  num_threads: 4
  log_level: "INFO"

Testing Installation

1. Run Basic Test

python -m hunyuan3d.tests.basic_test

2. Generate Test Model

import hunyuan3d

# Initialize generator
generator = hunyuan3d.Generator()

# Generate simple model
result = generator.generate(
    prompt="simple cube",
    output_format="obj"
)

Common Issues and Solutions

CUDA Related Issues

1. Error: CUDA not found

   • Solution: Verify CUDA installation and PATH

   echo $PATH  # Check CUDA in path
   nvidia-smi  # Verify GPU access
   

2. Error: GPU memory insufficient

   • Solution: Adjust memory usage in config

   system:
     gpu_memory_fraction: 0.6  # Reduce from 0.8
   

Python Environment Issues

1. Error: Package conflicts

   • Solution: Clean installation

   pip uninstall hunyuan3d
   pip install --no-cache-dir hunyuan3d
   

2. Error: Version mismatch

   • Solution: Check compatibility

   pip list | grep torch
   pip install torch==1.12.0  # Use compatible version
   

System Integration Issues

1. Error: Path not found

   • Solution: Verify environment setup

   echo $HUNYUAN3D_HOME
   ls $HUNYUAN3D_HOME/models
   

2. Error: Permission denied

   • Solution: Check file permissions

   chmod +x setup.py
   sudo chown -R user:user .
