ai.onnx.CumProd

ai.onnx · standard ONNX operator · ONNX opset ≥ 26

Description

Computes the cumulative product of input elements along a given axis. By default the product is inclusive (each output element is the product of all preceding elements including itself); setting exclusive to 1 shifts the window so the current element is excluded. Setting reverse to 1 performs the scan in the opposite direction along the axis.

See the ONNX CumProd spec for the reference semantics.

Use with @huggingface/kernels

The loader derives every required output's shape and logical dtype from the manifest contract and this call. It then allocates the result tensors automatically.

The version: 1 option selects the published kernel contract; it is independent of any operator opset, contrib since_version, or model version.

Replace each *Data placeholder with a typed array containing the corresponding input data.

import { getKernel } from "@huggingface/kernels";

const kernel = await getKernel("webgpu-kernels/ai.onnx.CumProd", { version: 1 });
const { y } = await kernel({ x: { data: xData, shape: [3] }, axis: 0 });
