[GitBox <gi...@apache.org>]

edmBernard opened a new issue #20033:
URL: https://github.com/apache/incubator-mxnet/issues/20033


   ## Description
   
   I try to reimplement HDRNet from this paper : https://groups.csail.mit.edu/graphics/hdrnet/
   They use an operator named **bilateral slice**.
   In pytorch it's [grid_sample](https://pytorch.org/docs/stable/nn.functional.html?highlight=grid_sample#torch.nn.functional.grid_sample) but the 5D versions.
   In mxnet, I was not able to find a equivalent. As there is different name accross deep learning framework I'm not sure if I simply miss it.
