-In this tutorial, we demonstrate how one can implement a Bayesian Neural Network using a combination of Turing and [Flux](https://github.com/FluxML/Flux.jl), a suite of machine learning tools. We will use Flux to specify the neural network's layers and Turing to implement the probabilistic inference, with the goal of implementing a classification algorithm.

 We will begin with importing the relevant libraries.
