  5. After the installation is complete, Xcode starts.

Command Line Tools are required to install. MAKE SURE YOU INSTALL THEM.

Set the Environment Variables

You must update several environment variables before you can compile and run OpenVINO™ applications. Open the macOS Terminal* or a command-line interface shell you prefer and run the following script to temporarily set your environment variables:

source /opt/intel/openvino/bin/

(Optional): The OpenVINO environment variables are removed when you close the shell. As an option, you can permanently set the environment variables as follows:

  1. Open the .bash_profile file in the current user home directory:
    vi ~/.bash_profile
  2. Press the 'i' key to switch to the insert mode.
  3. Add this line to the end of the file:
    source /opt/intel/openvino/bin/
  1. Save and close the file: press the Esc key and type :wq.
  2. To test your change, open a new terminal. You will see [] OpenVINO environment initialized.

The environment variables are set. Continue to the next section to configure the Model Optimizer.

Configure the Model Optimizer

IMPORTANT: This section is required. You must configure the Model Optimizer for at least one framework. The Model Optimizer will fail if you do not complete the steps in this section.

The Model Optimizer is a key component of the OpenVINO toolkit. You cannot do 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 IR is a pair of files that describe the whole model:

The Inference Engine reads, loads, and infers the IR files, using a common API across the CPU, GPU, or VPU hardware.

The Model Optimizer is a Python*-based command line tool (, which is located in /opt/intel/openvino/deployment_tools/model_optimizer.

Use this tool on models trained with popular deep learning frameworks such as Caffe*, TensorFlow*, MXNet*, and ONNX* to convert them to an optimized IR format that the Inference Engine can use.

This section explains how to use scripts to configure the Model Optimizer either for all of the supported frameworks at the same time or for individual frameworks. If you want to manually configure the Model Optimizer instead of using scripts, see the Using Manual Configuration Process section in the Configuring the Model Optimizer document.

For more information about the Model Optimizer, see the Model Optimizer Developer Guide.

Model Optimizer Configuration Steps

You can either configure the Model Optimizer for all supported frameworks at once, or for one framework at a time. Choose the option that best suits your needs. If you see error messages, make sure you installed all dependencies.

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 environment.

NOTE: If you installed OpenVINO to the non-default installation directory, replace /opt/intel/ with the directory where you installed the software to.

Option 1: Configure the Model Optimizer for all supported frameworks at the same time:

  1. Go to the Model Optimizer prerequisites directory:
    cd /opt/intel/openvino/deployment_tools/model_optimizer/install_prerequisites
  2. Run the script to configure the Model Optimizer for Caffe, TensorFlow, MXNet, Kaldi*, and ONNX:
    sudo ./

Option 2: Configure the Model Optimizer for each framework separately:

  1. Go to the Model Optimizer prerequisites directory:
    cd /opt/intel/openvino/deployment_tools/model_optimizer/install_prerequisites
  2. Run the script for your model framework. You can run more than one script:
    • For Caffe:
      sudo ./
    • For TensorFlow:
      sudo ./
    • For MXNet:
      sudo ./
    • For ONNX:
      sudo ./
    • For Kaldi:
      sudo ./

The Model Optimizer is configured for one or more frameworks. You are ready to use two short demos to see the results of running the OpenVINO toolkit and to verify your installation was successful. The demo scripts are required since they perform additional configuration steps. Continue to the next section.

Use the Demo Scripts to Verify Your Installation

IMPORTANT: This section is required. In addition to confirming that your installation was successful, the demo scripts perform additional steps, such as setting up your computer to use the Model Optimizer samples.

To learn more about the demo applications, see README.txt in /opt/intel/openvino/deployment_tools/demo/.

For detailed description of the pre-trained object detection and object recognition models, go to the Overview of OpenVINO toolkit Pre-Trained Models page.


  • The paths in this section assume you used the default installation directory to install the OpenVINO toolkit. If you installed the software to a directory other than /opt/intel/, update the directory path with the location where you installed the toolkit to.
  • If you installed the product as a root user, you must switch to the root mode before you continue: sudo -i.

Run the Image Classification Demo

  1. Go to the Inference Engine demo directory:
    cd /opt/intel/openvino/deployment_tools/demo
  2. Run the Image Classification demo:

The Image Classification demo uses the Model Optimizer to convert a SqueezeNet model to .bin and .xml Intermediate Representation (IR) files. The Inference Engine component uses these files.

For a brief description of the Intermediate Representation .bin and .xml files, see Configuring the Model Optimizer.

This demo creates the directory /home/<user>/inference_engine_samples/, builds the Image Classification Sample application and run it with the car.png image located in the demo directory. When the verification script completes, you will have the label and confidence for the top-10 categories:


This demo is complete. Continue to the next section to run the Inference Pipeline demo.

Run the Inference Pipeline Demo

  1. While still in /opt/intel/openvino/deployment_tools/demo/, run the Inference Pipeline demo:
    This demo uses car_1.bmp in /opt/intel/openvino/deployment_tools/demo/ to show an inference pipeline. This demo uses three pre-trained models. The demo uses vehicle recognition in which vehicle attributes build on each other to narrow in on a specific attribute. The demo works as follows:
  1. An object is identified as a vehicle.
  2. This identification is used as input to the next model, which identifies specific vehicle attributes, including the license plate.
  3. The attributes identified as the license plate are used as input to the third model, which recognizes specific characters in the license plate.

For more information about the demo, see the Security Barrier Camera Sample.​

  1. When the demo completes, two windows are open:
    • A console window that displays information about the tasks performed by the demo
    • An image viewer window that displays a picture similar to the following:

  2. Close the image viewer screen to end the demo.

In this section, you saw a preview of the OpenVINO toolkit capabilities.

Your have completed all the required installation, configuration, and build steps to work with your trained models using CPU.

Read the Summary for your next steps.


In this document, you installed the Intel® Distribution of OpenVINO™ toolkit and the external dependencies. In addition, you might have installed software and drivers that will let you use GPU or VPU to infer your models.

After the software was installed, you ran two demo applications to compile the extensions library and configured the Model Optimizer for one or more frameworks.

You are now ready to learn more about converting models trained with popular deep learning frameworks to the Inference Engine format, following the links below, or you can move on to running the sample applications.
