NPM module for SAP Leonardo Machine Learning Foundation - Functional Services

"SAP Leonardo Machine Learning foundation provides readily consumable pre-trained models, as well as customizable models." ---- SAP Leonardo Machine Learning Foundation - Functional Services

I have also written a book: Machine Learning mit SAP Leonardo (in German).

Usage

Install the npm package:

npm install sap-leonardo

Sign up a free account at SAP API Business Hub and get your API key.

Use e.g. the image classification service with your API key:

const leonardo = require("sap-leonardo");

var imageclassification = new leonardo.Imageclassification("apiKey");
imageclassification.classification("./elephant-114543_640.jpg")
  .then((body) => {
    var firstResult = body.predictions[0].results[0];
    console.log("result:", firstResult.label, firstResult.score);
    // result: tusker 0.7052137851715088
  })
  .catch((err) => { console.error(err); });

More examples can be found in the examples and src/test folder.
