Moving from Keras to Pytorch

Let us create an example network in keras first which we will try to port into Pytorch. Here I would like to give a piece of advice too. When you try to move from Keras to Pytorch take any network you have and try porting it to Pytorch. It will make you understand Pytorch in a much better way. Here I am trying to write one of the networks that gave pretty good results in the Quora Insincere questions classification challenge for me.
