Installation Steps

Install the Intel® Distribution of OpenVINO™ toolkit Core Components

If you have not downloaded the Intel® Distribution of OpenVINO™ toolkit, download the latest version. By default, the file is saved to the Downloads directory as w_openvino_toolkit_p_<version>.exe.
Go to the Downloads folder and double-click w_openvino_toolkit_p_<version>.exe. A window opens to let you choose your installation directory and components. The default installation directory is C:\Program Files (x86)\Intel\openvino_<version>, for simplicity, a shortcut to the latest installation is also created: C:\Program Files (x86)\Intel\openvino_2021. If you choose a different installation directory, the installer will create the directory for you:
Click Next.
You are asked if you want to provide consent to gather information. Choose the option of your choice. Click Next.
If you are missing external dependencies, you will see a warning screen. Write down the dependencies you are missing. You need to take no other action at this time. After installing the Intel® Distribution of OpenVINO™ toolkit core components, install the missing dependencies. The screen example below indicates you are missing two dependencies:
Click Next.
When the first part of installation is complete, the final screen informs you that the core components have been installed and additional steps still required:
Click Finish to close the installation wizard. A new browser window opens to the next section of the installation guide to set the environment variables. You are in the same document. The new window opens in case you ran the installation without first opening this installation guide.
If the installation indicated you must install dependencies, install them first. If there are no missing dependencies, you can go ahead and set the environment variables.

Set the Environment Variables

Note

: If you installed the Intel® Distribution of OpenVINO™ to the non-default install directory, replace C:\Program Files (x86)\Intel with the directory in which you installed the software.

You must update several environment variables before you can compile and run OpenVINO™ applications. Open the Command Prompt, and run the setupvars.bat batch file to temporarily set your environment variables:

cd C:\Program Files (x86)\Intel\openvino_2021\bin\

setupvars.bat

(Optional): OpenVINO toolkit environment variables are removed when you close the Command Prompt window. As an option, you can permanently set the environment variables manually.

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

Configure the Model Optimizer

Important

: These steps are 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.

Note

: If you see an error indicating Python is not installed when you know you installed it, your computer might not be able to find the program. For the instructions to add Python to your system environment variables, see Update Your Windows Environment Variables.

The Model Optimizer is a key component of the Intel® Distribution of 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:

.xml: Describes the network topology
.bin: Contains the weights and biases binary data

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 (mo.py), which is located in C:\Program Files (x86)\Intel\openvino_2021\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 on the Configuring the Model Optimizer page.

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

Model Optimizer Configuration Steps

You can configure the Model Optimizer either 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

: In the steps below:

If you you want to use the Model Optimizer from another installed versions of Intel® Distribution of OpenVINO™ toolkit installed, replace openvino_2021 with openvino_<version>, where <version> is the required version.

If you installed the Intel® Distribution of OpenVINO™ toolkit to the non-default installation directory, replace C:\Program Files (x86)\Intel with the directory where you installed the software.

These steps use a command prompt to make sure you see error messages.

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

Open a command prompt. To do so, type cmd in your Search Windows box and then press Enter. Type commands in the opened window:
Go to the Model Optimizer prerequisites directory.

cd C:\Program Files (x86)\Intel\openvino_2021\deployment_tools\model_optimizer\install_prerequisites

Run the following batch file to configure the Model Optimizer for Caffe*, TensorFlow* 1.x, MXNet*, Kaldi*, and ONNX*:

install_prerequisites.bat

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

Go to the Model Optimizer prerequisites directory:

cd C:\Program Files (x86)\Intel\openvino_2021\deployment_tools\model_optimizer\install_prerequisites

Run the batch file for the framework you will use with the Model Optimizer. You can use more than one:

For Caffe:

install_prerequisites_caffe.bat

For TensorFlow 1.x:

install_prerequisites_tf.bat

For TensorFlow 2.x:

install_prerequisites_tf2.bat

For MXNet:

install_prerequisites_mxnet.bat

For ONNX:

install_prerequisites_onnx.bat

For Kaldi:

install_prerequisites_kaldi.bat

The Model Optimizer is configured for one or more frameworks. Success is indicated by a screen similar to this:

You are ready to use two short demos to see the results of running the Intel Distribution of 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.

If you want to use a GPU or VPU, or update your Windows* environment variables, read through the Optional Steps section.

Use Verification Scripts to Verify Your Installation

Important

: This section is required. In addition to confirming your installation was successful, demo scripts perform other steps, such as setting up your computer to use the Inference Engine samples.

Note

: The paths in this section assume you used the default installation directory. If you used a directory other than C:\Program Files (x86)\Intel, update the directory with the location where you installed the software.
To verify the installation and compile two samples, run the verification applications provided with the product on the CPU:

Open a command prompt window.

Go to the Inference Engine demo directory:

cd C:\Program Files (x86)\Intel\openvino_2021\deployment_tools\demo\

Run the verification scripts by following the instructions in the next section.

Run the Image Classification Verification Script

To run the script, start the demo_squeezenet_download_convert_run.bat file:

demo_squeezenet_download_convert_run.bat

This script downloads a SqueezeNet model, uses the Model Optimizer to convert the model to the .&zwj;bin and .&zwj;xml Intermediate Representation (IR) files. The Inference Engine requires this model conversion so it can use the IR as input and achieve optimum performance on Intel hardware.
This verification script builds the Image Classification Sample Async application and run it with the car.png image in the demo directory. For a brief description of the Intermediate Representation, see Configuring the Model Optimizer.

When the verification script completes, you will have the label and confidence for the top-10 categories:

This demo is complete. Leave the console open and continue to the next section to run the Inference Pipeline demo.

Run the Inference Pipeline Verification Script

To run the script, start the demo_security_barrier_camera.bat file while still in the console:

demo_security_barrier_camera.bat

This script downloads three pre-trained model IRs, builds the [Security Barrier Camera Demo](@ref omz_demos_security_barrier_camera_demo_README) application, and runs it with the downloaded models and the car_1.bmp image from the demo directory to show an inference pipeline. The verification script uses vehicle recognition in which vehicle attributes build on each other to narrow in on a specific attribute.

First, an object is identified as a vehicle. This identification is used as input to the next model, which identifies specific vehicle attributes, including the license plate. Finally, the attributes identified as the license plate are used as input to the third model, which recognizes specific characters in the license plate.

When the demo completes, you have two windows open:

A console window that displays information about the tasks performed by the demo
An image viewer window that displays a resulting frame with detections rendered as bounding boxes, similar to the following:

Close the image viewer window to end the demo.

To learn more about the verification scripts, see README.txt in C:\Program Files (x86)\Intel\openvino_2021\deployment_tools\demo.

For detailed description of the OpenVINO™ pre-trained object detection and object recognition models, see the [Overview of OpenVINO™ toolkit Pre-Trained Models](@ref omz_models_intel_index) page.

In this section, you saw a preview of the Intel® Distribution of OpenVINO™ toolkit capabilities.
