grid_sample

[dingjingzhen]

It seems that mmcv does not support 5D grid_sample, is there any intention to implement it?

Hi, grid_sample in mmcv does not support 5D currently and we have no plan to support it recently.

5D grid_sampler (trilinear interpolation) can be implemented similar to 4D version, I have tried it in BGNET and got the same result. Waiting for tensorrt supporting 5D grid sample so that BGNET can be very fast in trt.
