We use the renderings of ShapeNet and Carvana in our experiments,which are available below:

Model Structure


Clone the Code Repository

git clone

Install Python Denpendencies

pip install -r UAGAN_requirements.txt

Update Settings in

You need to update hyperparametersthe of the model and path of the datasets :

    parser.add_argument('--image_dir', type=str, default='./dataset/img', help='input RGB image path')
    parser.add_argument('--mask_dir', type=str, default='./dataset/mask', help='input mask path')
    parser.add_argument('--lr', type=float, default='0.0002', help='learning rate')
    parser.add_argument('--batch_size', type=int, default='5', help='batch_size in training')
    parser.add_argument('--b1', type=float, default=0.5, help='adam: decay of first order momentum of gradient')
    parser.add_argument("--b2", type=float, default=0.999, help="adam: decay of first order momentum of gradient")
    parser.add_argument("--epoch", type=int, default=600, help="epoch in training")

Part of the experimental results are as follows

Get Started

To train UAGAN, you can simply use the following command:


Note: Since our paper has not been published yet, we only show the model structure and training code. When the paper is published, we will publish the full work of the paper. Welcome scholars to discuss and exchange.
