Your first neural network

You are going to build a neural network in PyTorch, using the hard way. Your input will be images of size (28, 28), so images containing 784 pixels. Your network will contain an input_layer (provided for you), a hidden layer with 200 units, and an output layer with 10 classes. The input layer has already been created for you. You are going to create the weights, and then do matrix multiplications, getting the results from the network.

Instructions

100 XP

Initialize with random numbers two matrices of weights, called weight_1 and weight_2.
Set the result of input_layer times weight_1 to hidden_1. Set the result of hidden_1 times weight_2 to output_layer.
