Question about the fp16 mode of mmdeploy grid_sampler

[kamiLight]

It seems to mmdeploy grid_sampler do not support fp16 (i.e nvinfer1::DataType::kHALF) according to https://github.com/open-mmlab/mmdeploy/blob/bc75c9d6c8940aa03d0e1e5b5962bd930478ba77/csrc/mmdeploy/backend_ops/tensorrt/grid_sampler/trt_grid_sampler.cpp#L110, so i wonder that mmdeploy grid_sampler will do nothing just return 1 if using fp16 mode? In this case, wouldn't we get the wrong result? Thanks!
