 1. Download the [pre-trained model](https://drive.google.com/drive/folders/1XlclE5EEX6OPWtQ9p1oubBDAqOcdhuqD?usp=sharing) (trained on [Human3.6M](http://vision.imar.ro/human3.6m/description.php) and [DensePose-COCO](https://densepose.org)) and put it into the `./data/pretrained_model` directory.
 
 2. Run the demo code. Using `--use_opendr` if the `opendr` package is successfully installed.
