Introduction

The Inference Engine can infer models in different formats with various input and output formats.

The open source version of Inference Engine includes the following plugins:

PLUGIN	DEVICE TYPES
CPU plugin	Intel® Xeon® with Intel® AVX2 and AVX512, Intel® Core™ Processors with Intel® AVX2, Intel® Atom® Processors with Intel® SSE
GPU plugin	Intel® Processor Graphics, including Intel® HD Graphics and Intel® Iris® Graphics
GNA plugin	Intel® Speech Enabling Developer Kit, Amazon Alexa* Premium Far-Field Developer Kit, Intel® Pentium® Silver processor J5005, Intel® Celeron® processor J4005, Intel® Core™ i3-8121U processor
MYRIAD plugin	Intel® Neural Compute Stick 2 powered by the Intel® Movidius™ Myriad™ X
Heterogeneous plugin	Heterogeneous plugin enables computing for inference on one network on several Intel® devices.

Use Custom OpenCV Builds for Inference Engine

NOTE: The recommended and tested version of OpenCV is 4.4.0.

Required versions of OpenCV packages are downloaded automatically during the building Inference Engine library. If the build script can not find and download the OpenCV package that is supported on your platform, you can use one of the following options:

• Download the most suitable version from the list of available pre-build packages from https://download.01.org/opencv/2020/openvinotoolkit from the <release_version>/inference_engine directory.

• Use a system-provided OpenCV package (e.g with running the apt install libopencv-dev command). The following modules must be enabled: imgcodecs, videoio, highgui.

• Get the OpenCV package using a package manager: pip, conda, conan etc. The package must have the development components included (header files and CMake scripts).

• Build OpenCV from source using the build instructions on the OpenCV site.

After you got the built OpenCV library, perform the following preparation steps before running the Inference Engine build:

1. Set the OpenCV_DIR environment variable to the directory where the OpenCVConfig.cmake file of you custom OpenCV build is located.
2. Disable the package automatic downloading with using the -DENABLE_OPENCV=OFF option for CMake-based build script for Inference Engine.

Add Inference Engine to Your Project

For CMake projects, set the InferenceEngine_DIR environment variable:

export InferenceEngine_DIR=/path/to/openvino/build/

Then you can find Inference Engine by find_package:

find_package(InferenceEngine REQUIRED)
target_link_libraries(${PROJECT_NAME} PRIVATE ${InferenceEngine_LIBRARIES})
