Get the value of an item in a tensor in Tensorflow.js

Question

How do I get the value out of a tensor in Tensorflow.js after specifying the index?

Answer 1

You can use datasync for this.

const newTensor = tf.tensor2d([[2,4],[5,6]]);
const tensorData = newTensor.dataSync();
console.log("data[0] is " + tensorData[0]);
console.log("data[3] is " + tensorData[3]);
