Pretrained Model

The checkpoints can be downloaded from here.

Place them under ./pretrained_models/ folder.

        └── model_ir_se50.pth        

Usage

python inference.py --input ./imgs/input.png --output ./imgs/output.png --checkpoint ./checkpoints/ckpt.pth 

Notice that the input image should be preprocessed folowing the EG3D. Note that the LT model implement has some difference with the original implement, but achieve the nearly same performance.

TODO

• Upload inference code and checkpoint.
• Release Training code.
• Release LT model and checkpoint.
