onnxjs-node v1.4.0

onnxjs-node

onnxjs-node is a Node.js binding of ONNXRuntime that works seamlessly with ONNX.js.

Installation

Install the latest stable version:

npm install onnxjs-node

NOTE: binary files will be pulled from github during the npm install process.

Supported Platforms

Usage

There are 2 options to import onnxjs-node.

• Option 1 - replace onnxjs by onnxjs-node:

  //const onnx = require('onnxjs');
  const onnx = require('onnxjs-node');
  
  // use 'onnx'
  // ...

• Option 2 - add a single line to require onnxjs-node:

  const onnx = require('onnxjs');
  require('onnxjs-node');  // this line can be put on the top as well
  
  // use 'onnx'
  // ...

After onnxjs-node is imported, the default inference session class of ONNX.js will be overwritten. Any existing ONNX.js code will continue to work and model will run by ONNXRuntime backend.

Backend Fallback

After onnxjs-node is imported, ONNXRuntime backend will be used by default. However, it is possible to fallback to other backend by specifying the session option backendHint:

session = new onnx.InferenceSession({backendHint: 'wasm'});  // use WebAssembly backend
