Part 2 of a PyTorch tutorial series shows how to initialize weights and biases as `nn.Parameter` tensors with `requires_grad=False` for a hardcoded neural network, setting up the forward pass covered in the next installment. For a tech team adopting PyTorch, understanding `nn.Parameter` and the `requires_grad` flag is foundational to controlling which parameters are updated during training vs. held fixed — relevant when fine-tuning pretrained models or implementing custom architectures.
In the previous article, we got started with expressing a neural network in the form of Python code.
In this article, we will continue building on that.
This is the neural network that we will recreate using code.
You can see the weights and biases shown in the diagram above. Let us now add them to our code.
We start with the basic neural network class:
