Once you have created the class for your Neural Network, you just need to instantiate it to create your model. Notice how the densenet layer is treated as a single layer inside the forward() method. In the following example we are creating a Neural Network class by making use of the densenet layer we created in the previous example. Once you have made use of the Sequential API to create the architecture of the Neural Network, you have to define the flow of data through this architecture inside the forward() method. It is inside the constructor of the class that you make of the Sequential API. Implement the forward() method of the class to define the flow of data through the model.Define the architecture of Neural Network in the constructor and using the constructor of the parent class to initialize parameters.Create a class for your Neural Network by sub-classing the nn.Module class. The steps for creating a Neural Network while using the Sequential API are. Notice how we are chaining a stack of multiple layers and treating it like a single layer- densenet.Ĭreating a Neural Network using the Sequential API is not much different from creating a Neural Network otherwise. # densenet is a stack of multiple layers chained together In this example, we are making use of nn.Sequential to create a stack of 3 Dense Layers and 2 ReLU activation layers in a specified order. You can notice that we have to store into self everything. The flow of data from one layer to the next layer is in the same order as they are passed to nn.Sequential. Sequential is a container of Modules that can be stacked together and run at the same time. This stack of layers is also treated as a single layer when defining the flow of data through the model. This stack of layers is treated as a single layer when creating the architecture of the Neural Network. The use of nn.Sequential allows you to stack Neural Network layers on top of each other. In this chapter, we will create the same Neural Network that we created in the last one, but using the Sequential API. Creating Neural Networks using the Pytorch Sequential API makes it simple, easy, and compact while reducing redundancy and complications. In this chapter of the Pytorch tutorial, you will learn about the Pytorch Sequential API and how to create a Neural Network using it. You have already learned how to create a Neural Network in Pytorch.
