subpixel regression

Hi,
I was going through the paper "Subpixel Heatmap Regression for Facial Landmark Localization" and it was mentioned the code is available in this repo. I did not find any reference to it in the release notes.
Could you please confirm it or share the code?
I was also wondering if the 2 stack hourglass model has also been released or not.
Tnx

The issue asks about unreleased code for subpixel heatmap regression and a 2-stack hourglass model mentioned in a paper. Check the repository's releases, branches, and documentation for any existing implementation. Look for related papers or citations in the codebase. Determine if the feature is planned, partially implemented, or needs to be developed from scratch.
