@Lambert-hpx Thanks for your execellent work!

After reading source code I found out that torch.nn.functional.grid_sample is used for sampling key point features. Then it occured to me that roi_align may be another solution for key point feature sampling? Have you guys tried roi_align and what's different with grid_sample?
