Detailed Description

Helper for constructing conditionally-executed subgraphs.

An If-conditional conditionally executes part of the network according to the following pseudo-code:

If condition is true then: output = trueSubgraph(trueInputs); Else output = falseSubgraph(falseInputs); Emit output

Condition is a 0D boolean tensor (representing a scalar). trueSubgraph represents a network subgraph that is executed when condition is evaluated to True. falseSubgraph represents a network subgraph that is executed when condition is evaluated to False.

The following constraints apply to If-conditionals:

• Both the trueSubgraph and falseSubgraph must be defined.
• The number of output tensors in both subgraphs is the same.
• The type and shape of each output tensor from true/false subgraphs are the same.

Member Function Documentation

addInput()

IIfConditionalInputLayer * nvinfer1::IIfConditional::addInput ( ITensor &  input )

inlinenoexcept

Add an If-conditional input.

Parameters

input

An input to the conditional that can be used by either or both of the conditional’s subgraphs.

IIfConditionalInputLayer

addOutput()

IIfConditionalOutputLayer * nvinfer1::IIfConditional::addOutput ( ITensor &  trueSubgraphOutput, ITensor &  falseSubgraphOutput  )

inlinenoexcept

Add an If-conditional output.

Parameters

trueSubgraphOutput	The output of the subgraph executed when the conditional evaluates to true.
falseSubgraphOutput	The output of the subgraph executed when the conditional evaluates to false.

Each output layer of an IIfConditional represents a single output of either the true-subgraph or the false-subgraph of an IIfConditional, depending on which subgraph was executed.

getName()

char const * nvinfer1::IIfConditional::getName ( ) const

inlinenoexcept

Return the name of the conditional.

setName()

setCondition()

IConditionLayer * nvinfer1::IIfConditional::setCondition ( ITensor &  condition )

inlinenoexcept

Set the condition tensor for this If-Conditional construct.

Parameters

condition

The condition tensor that will determine which subgraph to execute.

condition tensor must be a 0D execution tensor (scalar) with type DataType::kBOOL.

IConditionLayer

setName()

void nvinfer1::IIfConditional::setName ( char const *  name )

inlinenoexcept

Set the name of the conditional.

The name is used in error diagnostics. This method copies the name string.

Warning

The string name must be null-terminated, and be at most 4096 bytes including the terminator.
