ai.onnx.Identity

ai.onnx · standard ONNX operator · ONNX opset ≥ 16

Description

Copies the input tensor to the output unchanged. The output has the same shape, dtype, and values as the input.

See the ONNX Identity spec for the reference semantics.

• manifest.json — the op contract (source of truth)

Use with @huggingface/kernels

npm install --save-exact @huggingface/kernels@0.0.1-preview.2

Required output shapes and logical data types are inferred from the supplied inputs and attributes; result tensors are allocated automatically.

The version: 1 option selects the published kernel contract; it is independent of any operator opset, contrib since_version, or model version. It follows the v1 branch as fixes land. To pin exact artifact bytes, pass a 40-character commit revision instead of 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.Identity", { version: 1 });
const { y } = await kernel({ x: { data: xData, shape: [] } });
