Usage

🔧 Installation

Tested with the following environment:

• Python 3.10
• PyTorch 2.3.1
• CUDA Version 12.1

# clone the repository
git clone https://github.com/manycore-research/SpatialGen.git
cd SpatialGen

python -m venv .venv
source .venv/bin/activate

pip install -r requirements.txt
# Optional: fix the [flux inference bug](https://github.com/vllm-project/vllm/issues/4392)
pip install nvidia-cublas-cu12==12.4.5.8

📊 Dataset

We provide SpatialGen-Testset with 48 rooms, which labeled with 3D layout and 4.8K rendered images (48 x 100 views, including RGB, normal, depth maps and semantic maps) for MVD inference.

Inference

# Single image-to-3D Scene
bash scripts/infer_spatialgen_i2s.sh

# Text-to-image-to-3D Scene
bash scripts/infer_spatialgen_t2s.sh
