The latency difference between bilinear gridsample and nearest is significant in the same onnx model

Environment

TensorRT Version:8.6.2

NVIDIA GPU:Orin

NVIDIA Driver Version:

CUDA Version:12.2

CUDNN Version: 8904

Description

I have a onnx model. There are some gridsample operators in this model. I use /usr/src/tensorrt/bin/trtexec tool to build the model and test performance in Orin. The command like this:

/usr/src/tensorrt/bin/trtexec --useSpinWait --useCudaGraph --onnx=model.onnx --saveEngine=model.trt --fp16

Here is my problem:

1. When I set the attribute 'mode' of gridsample to 'bilinear', the latency is 1900+ms. (I know there must be something wrong)
2. When I set the attribute 'mode' of gridsample to 0, the latency is 680ms. It's a normal latency. I know I shouldn't set mode to 0, but I see in following code, if the 'mode' is not 'bilinear', 'nearest' or 'bicubic', 'interpolationMode' will be 'kNEAREST'.

https://github.com/onnx/onnx-tensorrt/blob/7583da4c62475e84b7be31f4b8fb0c101873d434/builtin_op_importers.cpp#L4386

### So why the latency in these two scenarios is significantly different?

And when I want to get the profiling of model with nsight-compute, an error occurs halfway through execution.

sudo -E /opt/nvidia/nsight-compute/2023.2.2/ncu --set full -f -o profile_6 /usr/src/tensorrt/bin/trtexec --useSpinWait --useCudaGraph --loadEngine=model.trt --fp16

I download new version nsight-compute from next website like 2023.3.0 and 2024.3.2, some errors also occurr and it can't start profiling.

Start at builtin_op_importers.cpp around line 4386 and review how GridSample modes are mapped, then reproduce the bilinear and nearest cases with the reported trtexec command on Orin. Separately, run the shown Nsight Compute commands and compare the profiling failures across versions; done means documenting a reproducible cause or narrowed diagnostic with the model, driver, and tool details.
