Concurrent

class mxnet.gluon.contrib.nn.Concurrent(axis=-1, prefix=None, params=None)[source]

Lays `Block`s concurrently.

This block feeds its input to all children blocks, and produce the output by concatenating all the children blocks’ outputs on the specified axis.

Example:

net = Concurrent()
# use net's name_scope to give children blocks appropriate names.
with net.name_scope():
    net.add(nn.Dense(10, activation='relu'))
    net.add(nn.Dense(20))
    net.add(Identity())
Parameters:axis (int, default -1) – The axis on which to concatenate the outputs.
__init__(axis=-1, prefix=None, params=None)[source]

Initialize self. See help(type(self)) for accurate signature.

Methods

__init__([axis, prefix, params]) Initialize self.
add(*blocks) Adds block on top of the stack.
apply(fn) Applies fn recursively to every child block as well as self.
cast(dtype) Cast this Block to use another data type.
collect_params([select]) Returns a ParameterDict containing this Block and all of its children’s Parameters(default), also can returns the select ParameterDict which match some given regular expressions.
forward(x) Overrides to implement forward computation using NDArray.
hybridize([active]) Activates or deactivates `HybridBlock`s recursively.Has no effect on non-hybrid children..
initialize([init, ctx, verbose, force_reinit]) Initializes Parameter s of this Block and its children.
load_parameters(filename[, ctx, …]) Load parameters from file previously saved by save_parameters.
load_params(filename[, ctx, allow_missing, …]) [Deprecated] Please use load_parameters.
name_scope() Returns a name space object managing a child Block and parameter names.
register_child(block[, name]) Registers block as a child of self.
register_forward_hook(hook) Registers a forward hook on the block.
register_forward_pre_hook(hook) Registers a forward pre-hook on the block.
save_parameters(filename) Save parameters to file.
save_params(filename) [Deprecated] Please use save_parameters.
summary(*inputs) Print the summary of the model’s output and parameters.

Attributes

name Name of this Block, without ‘_’ in the end.
params Returns this Block’s parameter dictionary (does not include its children’s parameters).
prefix Prefix of this Block.
