Detailed Description

This structure provides functions that fill inference options for ONNX OpenVINO Execution Provider. Please follow https://onnxruntime.ai/docs/execution-providers/OpenVINO-ExecutionProvider.html#summary-of-options.

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_typeTarget 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
paramsA 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
dirPath 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
nthreadsNumber of threads.
Returns
reference to this parameter structure.
Here is the call graph for this function:
