MNIST from scratch

This notebook walks through an example of training a TensorFlow model to do digit classification using the MNIST data set. MNIST is a labeled set of images of handwritten digits.

An example follows.

from __future__ import print_function

import XCPlayground

func isPrime(number: Int) -> Bool {
    if number <  2 { return false }
    let squareRoot = Int(sqrt(Double(number)))
    if squareRoot * squareRoot == number { return false }
    for i in 2..<Int(ceil(sqrt(Double(number)))) {
        if number % i == 0 { return false }
    }
