r"""A sequential container. | |||||
Modules will be added to it in the order they are passed in the | |||||
constructor. Alternatively, an ``OrderedDict`` of modules can be | |||||
passed in. The ``forward()`` method of ``Sequential`` accepts any | |||||
input and forwards it to the first module it contains. It then | |||||
"chains" outputs to inputs sequentially for each subsequent module, | |||||
finally returning the output of the last module. | |||||
The value a ``Sequential`` provides over manually calling a sequence | |||||
of modules is that it allows treating the whole container as a | |||||
single module, such that performing a transformation on the | |||||
``Sequential`` applies to each of the modules it stores (which are | |||||
each a registered submodule of the ``Sequential``). | |||||
What's the difference between a ``Sequential`` and a | |||||
:class:`torch.nn.ModuleList`? A ``ModuleList`` is exactly what it | |||||
sounds like--a list for storing ``Module`` s! On the other hand, | |||||
the layers in a ``Sequential`` are connected in a cascading way. | |||||
Example:: | |||||
# Using Sequential to create a small model. When `model` is run, | |||||
# input will first be passed to `Conv2d(1,20,5)`. The output of | |||||
# `Conv2d(1,20,5)` will be used as the input to the first | |||||
# `ReLU`; the output of the first `ReLU` will become the input | |||||
# for `Conv2d(20,64,5)`. Finally, the output of | |||||
# `Conv2d(20,64,5)` will be used as input to the second `ReLU` | |||||
model = nn.Sequential( | |||||
nn.Conv2d(1,20,5), | |||||
nn.ReLU(), | |||||
nn.Conv2d(20,64,5), | |||||
nn.ReLU() | |||||
) | |||||
# Using Sequential with OrderedDict. This is functionally the | |||||
# same as the above code | |||||
model = nn.Sequential(OrderedDict([ | |||||
('conv1', nn.Conv2d(1,20,5)), | |||||
('relu1', nn.ReLU()), | |||||

or used, and afterward they contain regular :class:`torch.nn.Parameter` s. | |||||
Lazy modules are convenient since they don't require computing some | |||||
module arguments, like the :attr:`in_features` argument of a | |||||
typical :class:`torch.nn.Linear`. | |||||
After construction, networks with lazy modules should first | |||||
be converted to the desired dtype and placed on the expected device. | |||||
This is because lazy modules only perform shape inference so the usual dtype | |||||
and device placement behavior applies. | |||||
The lazy modules should then perform "dry runs" to initialize all the components in the module. | |||||
These "dry runs" send inputs of the correct size, dtype, and device through | |||||
the network and to each one of its lazy modules. After this the network can be used as usual. | |||||

>>> # attaches an optimizer, since parameters can now be used as usual | |||||
>>> optim = torch.optim.SGD(mlp.parameters(), lr=0.01) | |||||
A final caveat when using lazy modules is that the order of initialization of a network's | |||||
parameters may change, since the lazy modules are always initialized after other modules. | |||||
For example, if the LazyMLP class defined above had a :class:`torch.nn.LazyLinear` module | |||||
first and then a regular :class:`torch.nn.Linear` second, the second module would be | |||||
initialized on construction and the first module would be initialized during the first dry run. | |||||
This can cause the parameters of a network using lazy modules to be initialized differently | |||||
than the parameters of a network without lazy modules as the order of parameter initializations, | |||||
which often depends on a stateful random number generator, is different. | |||||
Check :doc:`/notes/randomness` for more details. | |||||
Lazy modules can be serialized with a state dict like other modules. For example: | |||||
>>> lazy_mlp = LazyMLP() | |||||
>>> # The state dict shows the uninitialized parameters | |||||
>>> lazy_mlp.state_dict() | |||||
OrderedDict([('fc1.weight', Uninitialized parameter), | |||||

Lazy modules can load regular :class:`torch.nn.Parameter` s (i.e. you can serialize/deserialize | |||||
initialized LazyModules and they will remain initialized) | |||||
>>> full_mlp = LazyMLP() | |||||
>>> # Dry run to initialize another module | |||||
