Build the Neural Network =================== Neural networks comprise of layers/modules that perform operations on data. The `torch.nn <https://pytorch.org/docs/stable/nn.html>`_ namespace provides all the building blocks you need to build your own neural network. Every module in PyTorch subclasses the `nn.Module <https://pytorch.org/docs/stable/generated/torch.nn.Module.html>`_. A neural network is a module itself that consists of other modules (layers). This nested structure allows for building and managing complex architectures easily.
