const fs = require('fs');
const nnabla = require('nnabla-js');

const x = [...Array(28 * 28)].map(() => Math.random() * 2.0 - 1.0);

// Load your NNP file
fs.readFile('mnist.nnp', (_, data) => {
  // Build computation graph from NNP
  nnabla.NNP.fromNNPData(data).then((nnp) => {
    // Forward propagation with the specified executor
    const output = nnp.forward('runtime', { 'x0': x });
  });
});
