Methods
__call__
(*inputs, **kwargs)Call self as a function.
add_parameter
(name, parameter)Adds a Parameter instance.
add_sublayer
(name, sublayer)Adds a sub Layer instance.
apply
(fn)Applies
fn
recursively to every sublayer (as returned by.sublayers()
) as well as self.buffers
([include_sublayers])Returns a list of all buffers from current layer and its sub-layers.
children
()Returns an iterator over immediate children layers.
clear_gradients
()Clear the gradients of all parameters for this layer.
create_parameter
(shape[, attr, dtype, ...])Create parameters for this layer.
create_tensor
([name, persistable, dtype])Create Tensor for this layer.
create_variable
([name, persistable, dtype])Create Tensor for this layer.
eval
()Sets this Layer and all its sublayers to evaluation mode.
extra_repr
()Extra representation of this layer, you can have custom implementation of your own layer.
forward
(x[, mask_pad, stop_gradient, cache, ...])Compute convolution module. Args: x (paddle.Tensor): Input tensor (#batch, time, channels). mask_pad (paddle.Tensor): used for batch padding (#batch, 1, time), (0, 0, 0) means fake mask. cache (paddle.Tensor): left context cache, it is only used in causal convolution (#batch, channels, cache_t), (0, 0, 0) meas fake cache. Returns: paddle.Tensor: Output tensor (#batch, time, channels). paddle.Tensor: Output cache tensor (#batch, channels, time').
full_name
()Full name for this layer, composed by name_scope + "/" + MyLayer.__class__.__name__
load_dict
(state_dict[, use_structured_name])Set parameters and persistable buffers from state_dict.
named_buffers
([prefix, include_sublayers])Returns an iterator over all buffers in the Layer, yielding tuple of name and Tensor.
named_children
()Returns an iterator over immediate children layers, yielding both the name of the layer as well as the layer itself.
named_parameters
([prefix, include_sublayers])Returns an iterator over all parameters in the Layer, yielding tuple of name and parameter.
named_sublayers
([prefix, include_self, ...])Returns an iterator over all sublayers in the Layer, yielding tuple of name and sublayer.
parameters
([include_sublayers])Returns a list of all Parameters from current layer and its sub-layers.
register_buffer
(name, tensor[, persistable])Registers a tensor as buffer into the layer.
register_forward_post_hook
(hook)Register a forward post-hook for Layer.
register_forward_pre_hook
(hook)Register a forward pre-hook for Layer.
set_dict
(state_dict[, use_structured_name])Set parameters and persistable buffers from state_dict.
set_state_dict
(state_dict[, use_structured_name])Set parameters and persistable buffers from state_dict.
state_dict
([destination, include_sublayers, ...])Get all parameters and persistable buffers of current layer and its sub-layers.
sublayers
([include_self])Returns a list of sub layers.
to
([device, dtype, blocking])Cast the parameters and buffers of Layer by the give device, dtype and blocking.

register_state_dict_hook
- forward(x: ~paddle.Tensor, mask_pad: ~paddle.Tensor = Tensor(shape=[0, 0, 0], dtype=bool, place=Place(cpu), stop_gradient=True, []), cache: ~paddle.Tensor = Tensor(shape=[0, 0, 0, 0], dtype=float32, place=Place(cpu), stop_gradient=True, [])) Tuple[Tensor, Tensor] [source]
Compute convolution module. Args:
x (paddle.Tensor): Input tensor (#batch, time, channels). mask_pad (paddle.Tensor): used for batch padding (#batch, 1, time),
(0, 0, 0) means fake mask.
- cache (paddle.Tensor): left context cache, it is only
used in causal convolution (#batch, channels, cache_t), (0, 0, 0) meas fake cache.
- Returns:
paddle.Tensor: Output tensor (#batch, time, channels). paddle.Tensor: Output cache tensor (#batch, channels, time')
