Hook ( module, args, kwargs, output ) -> None or modified output Parameters Persistent ( bool) – whether the buffer is part of this module’s The buffer is not included in the module’s state_dict. That run on buffers, such as cuda, are ignored. Tensor ( Tensor or None) – buffer to be registered. Is that the latter will not be a part of this module’sīuffers can be accessed as attributes using given names. Only difference between a persistent buffer and a non-persistent buffer Thisīehavior can be changed by setting persistent to False. Buffers, byĭefault, are persistent and will be saved alongside parameters. Is not a parameter, but is part of the module’s state. This is typically used to register a buffer that should not to beĬonsidered a model parameter. register_buffer ( name, tensor, persistent = True ) ¶ ReturnsĪ handle that can be used to remove the added hook by calling The behavior of this function will change in future versions.

Prefix ( str) – prefix to prepend to all parameter names. Name of the parameter as well as the parameter itself. Returns an iterator over module parameters, yielding both the print ( idx, '->', m ) 0 -> ('', Sequential( (0): Linear(in_features=2, out_features=2, bias=True) (1): Linear(in_features=2, out_features=2, bias=True) )) 1 -> ('0', Linear(in_features=2, out_features=2, bias=True)) named_parameters ( prefix = '', recurse = True, remove_duplicate = True ) ¶ Sequential ( l, l ) > for idx, m in enumerate ( net.
