TIP: You can quick start with the Model Optimizer inside the OpenVINO™ Deep Learning Workbench (DL Workbench). DL Workbench is an OpenVINO™ UI that enables you to import a model, analyze its performance and accuracy, visualize the outputs, optimize and prepare the model for deployment on various Intel® platforms.
OpenVINO™ toolkit is a comprehensive toolkit for quickly developing applications and solutions that solve a variety of tasks including emulation of human vision, automatic speech recognition, natural language processing, recommendation systems, and many others. Based on latest generations of artificial neural networks, including Convolutional Neural Networks (CNNs), recurrent and attention-based networks, the toolkit extends computer vision and non-vision workloads across Intel® hardware, maximizing performance. It accelerates applications with high-performance, AI and deep learning inference deployed from edge to cloud.

NOTE: With OpenVINO™ 2020.4 release, Intel® Movidius™ Neural Compute Stick is no longer supported.
This guide provides step-by-step instructions on how to install the Intel® Distribution of OpenVINO™ toolkit. Links are provided for each type of compatible hardware including downloads, initialization and configuration steps. The following steps will be covered:
Download the Intel® Distribution of OpenVINO™ toolkit package file from Intel® Distribution of OpenVINO™ toolkit for Linux*. Select the Intel® Distribution of OpenVINO™ toolkit for Linux package from the dropdown menu.
COMPONENTSparameter in the
silent.cfgfile. For example, to install only CPU runtime for the Inference Engine, set
silent.cfg. To get a full list of available components for installation, run the
./install.sh --list_componentscommand from the unpacked OpenVINO™ toolkit package.
If you select the default options, the Installation summary GUI screen looks like this:
By default, the Intel® Distribution of OpenVINO™ is installed to the following directory, referred to as
/home/<USER>/intel/openvino_<version>/For simplicity, a symbolic link to the latest installation is also created:
NOTE: If there is an OpenVINO™ toolkit version previously installed on your system, the installer will use the same destination directory for next installations. If you want to install a newer version to a different directory, you need to uninstall the previously installed versions.
NOTE: The Intel® Media SDK component is always installed in the
/opt/intel/mediasdkdirectory regardless of the OpenVINO installation path chosen.
9. A Complete screen indicates that the core components have been installed:
The first core components are installed. Continue to the next section to install additional dependencies.
NOTE: If you installed the Intel® Distribution of OpenVINO™ to the non-default install directory, replace
/opt/intelwith the directory in which you installed the software.
These dependencies are required for:
You must update several environment variables before you can compile and run OpenVINO™ applications. Run the following script to temporarily set your environment variables:
Optional: The OpenVINO environment variables are removed when you close the shell. As an option, you can permanently set the environment variables as follows:
[setupvars.sh] OpenVINO environment initialized.
The environment variables are set. Continue to the next section to configure the Model Optimizer.
The Model Optimizer is a Python*-based command line tool for importing trained models from popular deep learning frameworks such as Caffe*, TensorFlow*, Apache MXNet*, ONNX* and Kaldi*.
The Model Optimizer is a key component of the Intel Distribution of OpenVINO toolkit. You cannot perform inference on your trained model without running the model through the Model Optimizer. When you run a pre-trained model through the Model Optimizer, your output is an Intermediate Representation (IR) of the network. The Intermediate Representation is a pair of files that describe the whole model:
.xml: Describes the network topology
.bin: Contains the weights and biases binary data
For more information about the Model Optimizer, refer to the Model Optimizer Developer Guide.
You can choose to either configure all supported frameworks at once OR configure one framework at a time. Choose the option that best suits your needs. If you see error messages, make sure you installed all dependencies.
NOTE: Since the TensorFlow framework is not officially supported on CentOS*, the Model Optimizer for TensorFlow can't be configured and ran on those systems.
IMPORTANT: The Internet access is required to execute the following steps successfully. If you have access to the Internet through the proxy server only, please make sure that it is configured in your OS environment.
Option 1: Configure all supported frameworks at the same time
Option 2: Configure each framework separately
Configure individual frameworks separately ONLY if you did not select Option 1 above.
You have completed all required installation, configuration and build steps in this guide to use your CPU to work with your trained models.
To enable inference on other hardware, see:
Or proceed to the Get Started to get started with running code samples and demo applications.
The steps in this section are required only if you want to enable the toolkit components to use processor graphics (GPU) on your system.
Install the Intel® Graphics Compute Runtime for OpenCL™ driver components required to use the GPU plugin and write custom layers for Intel® Integrated Graphics. The drivers are not included in the package and must be installed separately.
NOTE: To use the Intel® Iris® Xe MAX Graphics, see the Intel® Iris® Xe MAX Graphics with Linux* page for driver installation instructions.
To install the drivers, make sure you have the internet connection and run the installation script:
The script compares the driver version on the system to the current version. If the driver version on the system is higher or equal to the current version, the script does not install a new driver. If the version of the driver is lower than the current version, the script uninstalls the lower and installs the current version with your permission:
Higher hardware versions require a higher driver version, namely 20.35 instead of 19.41. If the script fails to uninstall the driver, uninstall it manually. During the script execution, you may see the following command line output:
Ignore this suggestion and continue.
You can also find the most recent version of the driver, installation procedure and other information on the Intel® software for general purpose GPU capabilities site.
You've completed all required configuration steps to perform inference on processor graphics. Proceed to the Get Started to get started with running code samples and demo applications.
These steps are only required if you want to perform inference on Intel® Movidius™ NCS powered by the Intel® Movidius™ Myriad™ 2 VPU or Intel® Neural Compute Stick 2 powered by the Intel® Movidius™ Myriad™ X VPU. See also the Get Started page for Intel® Neural Compute Stick 2:
You've completed all required configuration steps to perform inference on Intel® Neural Compute Stick 2. Proceed to the Get Started to get started with running code samples and demo applications.
