## Related Issue closes #19689 ## Why The Relax AffineGrid op only handled 2D (4D theta/grid); 5D 3D inputs from ONNX failed. ## How - Generalize struct-info inference to 2D/3D via spatial = size_sinfo->ndim. - Branch TOPI affine_grid compute on 2D vs 3D. - Add the 3D permute path in the frontend and a test_affine_grid_3d case. --------- Signed-off-by: Guan-Ming (Wesley) Chiu <105915352+guan404ming@users.noreply.github.com>
