Detailed Description

Base class for all layer classes in a network definition.

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

virtual ITensor* nvinfer1::ILayer::getInput ( int index ) const

pure virtual

Get the layer input corresponding to the given index.

Parameters

index The index of the input tensor.

Returns: The input tensor, or nullptr if the index is out of range or the tensor is optional(IRNNLayer and IRNNv2Layer).

virtual const char* nvinfer1::ILayer::getName ( ) const

pure virtual

Return the name of a layer.

See Also: setName()

virtual ITensor* nvinfer1::ILayer::getOutput ( int index ) const

pure virtual

Get the layer output corresponding to the given index.

Returns: The indexed output tensor, or nullptr if the index is out of range or the tensor is optional(IRNNLayer and IRNNv2Layer).

virtual DataType nvinfer1::ILayer::getOutputType ( int index ) const

pure virtual

get the output type of this layer

Parameters

index the index of the output

Returns: the output precision. If no precision has been set, DataType::kFLOAT will be returned, unless the output type is inherently DataType::kINT32.

See Also: getOutputType() outputTypeIsSet() resetOutputType()

virtual DataType nvinfer1::ILayer::getPrecision ( ) const

pure virtual

get the computational precision of this layer

Returns: the computational precision

See Also: setPrecision() precisionIsSet() resetPrecision()

virtual LayerType nvinfer1::ILayer::getType ( ) const

pure virtual

Return the type of a layer.

See Also: LayerType

virtual bool nvinfer1::ILayer::outputTypeIsSet ( int index ) const

pure virtual

whether the output type has been set for this layer

Parameters

index the index of the output

Returns: whether the output type has been explicitly set

See Also: setOutputType() getOutputType() resetOutputType()

virtual bool nvinfer1::ILayer::precisionIsSet ( ) const

pure virtual

whether the computational precision has been set for this layer

Returns: whether the computational precision has been explicitly set

See Also: setPrecision() getPrecision() resetPrecision()

virtual void nvinfer1::ILayer::resetOutputType ( int index )

pure virtual

reset the output type for this layer

Parameters

index the index of the output

See Also: setOutputType() getOutputType() outputTypeIsSet()

virtual void nvinfer1::ILayer::resetPrecision ( )

pure virtual

reset the computational precision for this layer

See Also: setPrecision() getPrecision() precisionIsSet()

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

pure virtual

replace an input of this layer with a specific tensor

Note that this method cannot change the number of inputs to a layer. The index argument must be less than the value of getNbInputs()

Parameters

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

virtual void nvinfer1::ILayer::setName ( const char * name )

pure virtual

Set the name of a layer.

This method copies the name string.

See Also: getName()

virtual void nvinfer1::ILayer::setOutputType	(	int	index,
		DataType	dataType
	)

pure virtual

Set the output type of this layer.

setting the output type constrains TensorRT to choose implementations which generate output data with the given type. If it is not set, TensorRT will select the implementation based on performance considerations and the flags specified to the builder.

Parameters

index	the index of the output to set
dataType	the type of the output

See Also: getOutputType() outputTypeIsSet() resetOutputType()

virtual void nvinfer1::ILayer::setPrecision ( DataType dataType )

pure virtual

Set the computational precision of this layer.

setting the precision forces TensorRT to choose implementations which run at this precision. If precision is not set, TensorRT will select the computational precision based on performance considerations and the flags specified to the builder.

Parameters

precision the computational precision.
