Installation

1. Clone repository

git clone https://github.com/Len-Li/Lift3D.git
cd Lift3D

2. Set up conda environment or use your existing one

conda create --name Lift3D python=3.8
conda activate Lift3D

3. Install the key requirement

pip install torch torchvision torchaudio
pip install configargparse munch pillow

3. Download the checkpoint and object latents

• Onedrive link

Please download lift3d_ckp.pt and obj_latent.pth, then put them in the folder ckp

Inference

python infer.py

The rendered images and semantic mask are saved in the folder test_out.
