All Implemented Interfaces:

AutoCloseable

@Namespace(value="nvinfer1")
 @Properties(inherit=nvinfer.class)
public class IInt8LegacyCalibrator
extends IInt8Calibrator

Legacy calibrator left for backward compatibility with TensorRT 2.0. This calibrator requires user parameterization, and is provided as a fallback option if the other calibrators yield poor results.

Constructor Detail

IInt8LegacyCalibrator

public IInt8LegacyCalibrator()

Default native constructor.

IInt8LegacyCalibrator

public IInt8LegacyCalibrator(long size)

Native array allocator. Access with Pointer.position(long).

IInt8LegacyCalibrator

public IInt8LegacyCalibrator(Pointer p)

Pointer cast constructor. Invokes Pointer(Pointer).

Method Detail

position

public IInt8LegacyCalibrator position(long position)

Overrides:

position in class IInt8Calibrator

getPointer

public IInt8LegacyCalibrator getPointer(long i)

Overrides:

getPointer in class IInt8Calibrator

getAlgorithm

@Virtual
 @NoException(value=true)
public nvinfer.CalibrationAlgoType getAlgorithm()

Signal that this is the legacy calibrator.

Overrides:

getAlgorithm in class IInt8Calibrator

Returns:

The algorithm used by the calibrator.

getQuantile

@Virtual(value=true)
 @NoException(value=true)
 @Const(value={false,false,true})
public double getQuantile()

\brief The quantile (between 0 and 1) that will be used to select the region maximum when the quantile method is in use. See the user guide for more details on how the quantile is used.

getRegressionCutoff

@Virtual(value=true)
 @NoException(value=true)
 @Const(value={false,false,true})
public double getRegressionCutoff()

\brief The fraction (between 0 and 1) of the maximum used to define the regression cutoff when using regression to determine the region maximum. See the user guide for more details on how the regression cutoff is used

readHistogramCache

@Virtual(value=true)
 @Const
 @NoException(value=true)
public Pointer readHistogramCache(@Cast(value="std::size_t*") @ByRef
                                                                                         LongPointer length)

\brief Load a histogram. Histogram generation is potentially expensive, so it can be useful to generate the histograms once, then use them when exploring the space of calibrations. The histograms should be regenerated if the network structure changes, or the input data set changes, and it is the responsibility of the application to ensure this.

Parameters:

length - The length of the cached data, that should be set by the called function. If there is no data, this should be zero.

Returns:

A pointer to the cache, or nullptr if there is no data.

writeHistogramCache

@Virtual(value=true)
 @NoException(value=true)
public void writeHistogramCache(@Const
                                                                               Pointer ptr,
                                                                               @Cast(value="std::size_t")
                                                                               long length)

\brief Save a histogram cache.

Parameters:

ptr - A pointer to the data to cache.

length - The length in bytes of the data to cache.
