torch.nn.Module is a base class for all neural network modules in PyTorch. It is designed to be a building block for creating complex neural network architectures.
The torch.nn.Module class provides several important methods and attributes that are used to define the neural network architecture, including:
- `__init__(self)`: Constructor method that initializes the module and its parameters.
- `forward(self, input)`: Defines the forward pass of the module, where input is passed through the layers of the module to produce an output.
- `parameters(self)`: Returns an iterator over the module's parameters (i.e. weights and biases).
- `children(self)`: Returns an iterator over the child modules of the current module.
- `to(self, device)`: Moves the module to the specified device (i.e. CPU or GPU).
In addition to these methods, the torch.nn.Module class also provides a number of other utility methods and attributes, such as `train()` and `eval()` for setting the module's training mode, and `state_dict()` and `load_state_dict()` for saving and loading the module's parameters.
