Detailed Description

Generate an output tensor with specified mode.

The fill layer has two variants, static and dynamic. Static fill specifies its parameters at layer creation time via Dims and the get/set accessor functions of the IFillLayer. Dynamic fill specifies one or more of its parameters as ITensors, by using ILayer::setInput to add a corresponding input. The corresponding static parameter is used if an input is missing or null.

The shape of the output is specified by the parameter Dimension, or if non-null and present, the first input, which must be a 1D Int32 shape tensor. Thus an application can determine if the IFillLayer has a dynamic output shape based on whether it has a non-null first input.

Alpha and Beta are treated differently based on the Fill Operation specified. See details in IFillLayer::setAlpha(), IFillLayer::setBeta(), and IFillLayer::setInput().

A fill layer can produce a shape tensor if the following restrictions are met:

The FillOperation is kLINSPACE.
The output is an Int32 or Float tensor within the volume limit of a shape tensor.
There is at most one input, and if so, that input is input 0.
If input 0 exists, the length of the output tensor must be computable by constant folding.

Warning: Do not inherit from this class, as doing so will break forward-compatibility of the API and ABI.

Constructor & Destructor Documentation

◆ ~IFillLayer()

virtual nvinfer1::IFillLayer::~IFillLayer ( )

protectedvirtualdefaultnoexcept

Member Function Documentation

◆ getAlpha()

double nvinfer1::IFillLayer::getAlpha ( ) const

inlinenoexcept

Get the value of alpha parameter.

Returns: A double value of alpha.

If the second input is present and non-null, this function returns -1.0.

See also: setAlpha

◆ getBeta()

double nvinfer1::IFillLayer::getBeta ( ) const

inlinenoexcept

Get the value of beta parameter.

Returns: A double value of beta.

If the third input is present and non-null, this function returns -1.0.

See also: setBeta

◆ getDimensions()

Dims nvinfer1::IFillLayer::getDimensions ( ) const

inlinenoexcept

Get the output tensor's dimensions.

Returns: The output tensor's dimensions, or an invalid Dims structure.

If the first input is present and non-null, this function returns a Dims with nbDims = -1.

See also: setDimensions

◆ getOperation()

FillOperation nvinfer1::IFillLayer::getOperation ( ) const

inlinenoexcept

Get the fill operation for the layer.

See also: setOperation(), FillOperation

◆ setAlpha()

void nvinfer1::IFillLayer::setAlpha ( double alpha )

inlinenoexcept

Set the alpha parameter.

Parameters

alpha has different meanings for each operator:

Operation | Usage kLINSPACE | the start value, defaults to 0.0; kRANDOM_UNIFORM | the minimum value, defaults to 0.0; kRANDOM_NORMAL | the mean of the normal distribution, default is 0.0;

If a second input had been used to create this layer, that input is reset to null by this method.

See also: getAlpha

◆ setBeta()

void nvinfer1::IFillLayer::setBeta ( double beta )

inlinenoexcept

Set the beta parameter.

Parameters

beta	has different meanings for each operator:

Operation | Usage kLINSPACE | the delta value, defaults to 1.0; kRANDOM_UNIFORM | the maximal value, defaults to 1.0; kRANDOM_NORMAL | the standard deviation of the normal distribution, default is 1.0;

If a third input had been used to create this layer, that input is reset to null by this method.

See also: getBeta

◆ setDimensions()

void nvinfer1::IFillLayer::setDimensions ( Dims dimensions )

inlinenoexcept

Set the output tensor's dimensions.

Parameters

dimensions The output tensor's dimensions.

If the first input had been used to create this layer, that input is reset to null by this method.

See also: getDimensions

◆ setInput()

void nvinfer1::ILayer::setInput	(	int32_t	index,
		ITensor &	tensor
	)

inlinenoexcept

replace an input of this layer with a specific tensor.

Parameters

index	the index of the input to set.
tensor	the new input tensor

Indices for kLINSPACE are described as:

0: Shape tensor, represents the output tensor's dimensions.
1: Start, a scalar, represents the start value.
2: Delta, a 1D tensor, length equals to shape tensor's nbDims, represents the delta value for each dimension.

Indices for kRANDOM_UNIFORM are described as:

0: Shape tensor, represents the output tensor's dimensions.
1: Minimum, a scalar, represents the minimum random value.
2: Maximum, a scalar, represents the maximal random value.

Indices for kRANDOM_NORMAL are described as:

0: Shape tensor, represents the output tensor's dimensions.
1: Mean, a scalar, represents the mean of the normal distribution,.
2: Scale, a scalar, represents the standard deviation of the normal distribution.

Using the corresponding setter resets the input to null.

If either inputs 1 or 2, is non-null, then both must be non-null and have the same data type.

If this function is called for an index greater or equal to getNbInputs(), then afterwards getNbInputs() returns index + 1, and any missing intervening inputs are set to null.

◆ setOperation()

void nvinfer1::IFillLayer::setOperation ( FillOperation op )

inlinenoexcept

Set the fill operation for the layer.
