Description

Log

data = torch.ones((1, 1, 512, 32, 32), dtype=torch.float32)
grid = torch.ones((1, 512, 32, 32, 3), dtype=torch.float32).cuda()
res = torch.nn.functional.grid_sample(img, grid)

The ONNX model performs inference correctly, but conversion to TensorRT fails. The error indicates that the GridSample operator does not support 5D input format.

Research direction

Start with the provided PyTorch grid_sample example and the TensorRT 10.6.0.26 conversion error, then compare the successful ONNX inference with the failing TensorRT conversion. Determine whether 5D GridSample conversion is supported; done means the failure is fixed or the limitation and supported behavior are clearly established.
