Installation

Please follow the instructions here for installation.

Preparation after Installation

• Step 1: please clone the official HRNet repo.

git clone https://github.com/leoxiaobin/deep-high-resolution-net.pytorch

• Step 2: download the pretrained HRNet model checkpoints using this link, and put the downloaded folder models inside the deep-high-resolution-net.pytorch/ directory.
• Step 3: replace the demo folder in the original deep-high-resolution-net.pytorch repository with the demo folder from this repository.
  We have also put the code together and uploaded to this link which you can refer to if you have any questions on the preparation.
