oneflow.nn.ParameterList¶
-
class
oneflow.nn.
ParameterList
(parameters=None)¶ Holds parameters in a list.
ParameterList
can be indexed like a regular Python list, but parameters it contains are properly registered, and will be visible by allModule
methods.The interface is consistent with PyTorch. The documentation is referenced from: https://pytorch.org/docs/1.10/generated/torch.nn.ParameterList.html?#torch.nn.ParameterList.
- Parameters
parameters (iterable, optional) – an iterable of
Parameter
