Pytorch grid_sample
WebGrid Sample 1d pytorch cuda extension of grid sample 1d. Since pytorch only supports grid sample 2d/3d, I extend the 1d version for efficiency. The forward pass is 2~3x faster than pytorch grid sample. setup Pytorch == 1.7.1 CUDA == 10.1 Other versions of pytorch or cuda may work but I haven't test. you can choose to manually build it or use JIT

WebMay 25, 2024 · My own implementation of bilinear sampling (not just grid_sample, but the whole original sampling, based on grid_sample) performs much faster in Pytorch and is converted to TRT successfully. But my custom bilinear sampling in TRT is slower, than the one in Pytorch (5.6 ms vs 2.0 ms).
WebI am trying to understand how the "grid_sample" function works in Pytorch. For example, for an input matrix of size (2,2) and a flow field of shape (4,4,2), how does the function work mathematically?
