mxnet.gluon.nn.Lambda¶

class mxnet.gluon.nn.Lambda(function, prefix=None)[source]¶

Wraps an operator or an expression as a Block object.

Parameters

function (str or function) –
Function used in lambda must be one of the following: 1) the name of an operator that is available in ndarray. For example:
```
block = Lambda('tanh')
```
1. a function that conforms to def function(*args). For example:
```
block = Lambda(lambda x: nd.LeakyReLU(x, slope=0.1))
```
Inputs –
- ** args *: one or more input data. Their shapes depend on the function.
Output –
- ** outputs *: one or more output data. Their shapes depend on the function.

__init__(function, prefix=None)[source]¶: Initialize self. See help(type(self)) for accurate signature.

Methods

`__init__`(function[, prefix])	Initialize self.
`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`(*args)	Overrides to implement forward computation using `NDArray`.
`hybridize`([active])	Activates or deactivates `HybridBlock` s recursively.
`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`.
