Member Function Documentation

build()

bool SampleOnnxMnistCoordConvAC::build

(

)

Function builds the network engine.

Creates the network, configures the builder and creates the network engine.

This function creates the Onnx MNIST network by parsing the Onnx model and builds the engine that will be used to run MNIST (mEngine)

Returns

Returns true if the engine was created successfully and false otherwise

Here is the call graph for this function:

infer()

bool SampleOnnxMnistCoordConvAC::infer

(

)

Runs the TensorRT inference engine for this sample.

This function is the main execution function of the sample. It allocates the buffer, sets inputs and executes the engine.

Here is the call graph for this function:

constructNetwork()

bool SampleOnnxMnistCoordConvAC::constructNetwork ( SampleUniquePtr< nvinfer1::IBuilder > &  builder, SampleUniquePtr< nvinfer1::INetworkDefinition > &  network, SampleUniquePtr< nvinfer1::IBuilderConfig > &  config, SampleUniquePtr< nvonnxparser::IParser > &  parser  )

private

Parses an ONNX model for MNIST and creates a TensorRT network.

Uses a ONNX parser to create the Onnx MNIST Network and marks the output layers.

Parameters

network	Pointer to the network that will be populated with the Onnx MNIST network
builder	Pointer to the engine builder

Here is the caller graph for this function:

verifyOutput()

bool SampleOnnxMnistCoordConvAC::verifyOutput ( const samplesCommon::BufferManager &  buffers )

private

Classifies digits and verify result.

Returns

whether the classification output matches expectations
