• ### Pure Python vs NumPy vs TensorFlow Performance

1.20s. While the NumPy and TensorFlow solutions are competitive (on CPU) the pure Python implementation is a distant third. While Python is a robust general-purpose programming language its libraries targeted towards numerical computation will win out any day when it comes to large batch operations on arrays.
