 ## Demo
 Warning: The released model is trained with mostly upright standing scans with weak perspectie projection and the pitch angle of 0 degree. Reconstruction quality may degrade for images highly deviated from trainining data.
 1. run the following script to download the pretrained models from the following link and copy them under `./PIFu/checkpoints/`.
