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`.
