Sample points in volume mode

[OrangeSodahub]

Seems that the volume has the shape of X-Y-Z while the sample_pts has the coords in x-y-z sequence, so does this satisfy the F.grid_sample's inputs? I remenber that the volume should have Z-Y-X shape.

sample_features = F.grid_sample(features, norm_pts, align_corners=True, padding_mode="border")
