Import/Export of JSON for model is not working

What is wrong?

Export/Import functionality of the library is not working, the JSON is not in the correct format to be considered JSON.

Where does it happen?

Windows 10 node version 8

How do we replicate the issue?

`const brain = require('brain.js);

var net = new brain.recurrent.RNN();

net.train([{input: [0, 0], output: [0]}, {input: [0, 1], output: [1]}, {input: [1, 0], output: [1]}, {input: [1, 1], output: [0]}]);

var output = net.run([0, 0]); // [0] output = net.run([0, 1]); // [1] output = net.run([1, 0]); // [1] output = net.run([1, 1]); // [0]

console.log(net.toJSON()) // JSON is in incorrect format, am i missing something? `

How important is this (1-5)?

4 - love this library but can’t use it for Production use cases until i can export/import

Expected behavior (i.e. solution)

JSON is exported in valid format

N/A - love this Library tho

net.fromJSON(JSON.parse("input-output-trainedmodel.json"));

May be the problem. JSON.parse reads a string in, you want to pass the string of the source of input-output-trainedmodel.json

Is there a trick to reading it in from an external source?

Yea, just use

const fs = require('fs');

and then later:

console.log(json) // JSON is in different format
fs.writeFileSync("input-output-trainedmodel.json", JSON.stringify(json));
var net = new brain.recurrent.RNN();
net.fromJSON(
  JSON.parse(
    fs.readFileSync("input-output-trainedmodel.json").toString()
  )
);

Yes you are correct. Thanks so much! Sorry, I knew that the reading in was a javascript issue not a brain js issue I just didn’t know how to achieve it. I’m a .NET developer by trade so little rusty with the ol’ JS side of things.

Thanks again.
