Hello!
I was wondering if is there a smart way to achieve what I call (for lack of better definition) one to many grid_sample.
What do I mean by that? instead of sampling  N(many) (C x IH x IW) images using N(many) (OH x OW x 2) grids is it possible to have  grid_sample to have a single image  1 (C x IH x IW) sampled with N (OH x OW x 2) grids? and why not also Many to One in wich many images are sampled at the same locations?
Is there a smart/fast way to achieve this (instead of looping over N calls to grid_sample)? It could be really interesting especially for sparse object detection in very big images or volumes.
