Constructor & Destructor Documentation

OpenVINO() [1/2]

GAPI_WRAP cv::gapi::onnx::ep::OpenVINO::OpenVINO ( const std::string & dev_type )

inlineexplicit

Class constructor.

Constructs OpenVINO parameters based on device type information.

Parameters

dev_type

Target device type to use. ("CPU", "GPU", "GPU.0" etc)

OpenVINO() [2/2]

GAPI_WRAP cv::gapi::onnx::ep::OpenVINO::OpenVINO ( const std::map< std::string, std::string > & params )

inlineexplicit

Class constructor.

Constructs OpenVINO parameters based on map of options passed.

Parameters

params

A map of parameter names and their corresponding string values.

Member Function Documentation

cfgCacheDir()

GAPI_WRAP OpenVINO & cv::gapi::onnx::ep::OpenVINO::cfgCacheDir ( const std::string & dir )

inline

Specifies OpenVINO Execution Provider cache dir.

This function is used to explicitly specify the path to save and load the blobs enabling model caching feature.

Parameters

dir	Path to the directory what will be used as cache.

Returns

reference to this parameter structure.

Here is the call graph for this function:

cfgEnableDynamicShapes()

GAPI_WRAP OpenVINO & cv::gapi::onnx::ep::OpenVINO::cfgEnableDynamicShapes ( )

inline

Enables OpenVINO Execution Provider dynamic shapes.

This function is used to enable OpenCL queue throttling for GPU devices (reduces CPU utilization when using GPU). This function is used to enable work with dynamic shaped models whose shape will be set dynamically based on the infer input image/data shape at run time in CPU.

Returns

reference to this parameter structure.

Here is the call graph for this function:

cfgEnableOpenCLThrottling()

GAPI_WRAP OpenVINO & cv::gapi::onnx::ep::OpenVINO::cfgEnableOpenCLThrottling ( )

inline

Enables OpenVINO Execution Provider opencl throttling.

This function is used to enable OpenCL queue throttling for GPU devices (reduces CPU utilization when using GPU).

Returns

reference to this parameter structure.

Here is the call graph for this function:

cfgNumThreads()

GAPI_WRAP OpenVINO & cv::gapi::onnx::ep::OpenVINO::cfgNumThreads ( size_t nthreads )

inline

Specifies OpenVINO Execution Provider number of threads.

This function is used to override the accelerator default value of number of threads with this value at runtime.

Parameters

nthreads

Number of threads.

Returns

reference to this parameter structure.

Here is the call graph for this function:
