OpenVINO Core API

OpenVINO Core API contains two folders:

• ngraph - is a legacy API, this API is no longer being developed. Only aliases to new operations and operation sets extend this API.
• openvino - current public API, this part is described below.

Structure of Core API

 
 openvino/                  // Common folder with OpenVINO 2.0 API
    core/                   // Contains common classes which are responsible for model representation
    op/                     // Contains all supported OpenVINO operations
    opsets/                 // Contains definitions of each official OpenVINO opset
    pass/                   // Defines classes for developing transformation and several common transformations
    runtime/                // Contains OpenVINO tensor definition
 

Main structures for model representation

• ov::Model is located in openvino/core/model.hpp and provides API for model representation. For more details, read OpenVINO Model Representation Guide.
• ov::Node is a base class for all OpenVINO operations, the class is located in the openvino/core/node.hpp.
• ov::Shape and ov::PartialShape classes represent shapes in OpenVINO, these classes are located in the openvino/core/shape.hpp and openvino/core/partial_shape.hpp respectively. For more information, read OpenVINO Shapes representation.
• ov::element::Type class represents element type for OpenVINO Tensors and Operations. The class is located in the openvino/core/type/element_type.hpp.
• ov::Tensor is used for memory representation inside OpenVINO. The class is located in the openvino/runtime/tensor.hpp.
