The development and target platforms have the same requirements, but you can select different components during the installation, based on your intended use.
This guide provides step-by-step instructions on how to install the Intel® Distribution of OpenVINO™ toolkit with FPGA Support. 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* with FPGA Support. Select the Intel® Distribution of OpenVINO™ toolkit for Linux with FPGA Support package from the dropdown menu.
The first core components are installed. Continue to the next section to install additional dependencies.
These dependencies are required for:
The dependencies are installed. 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.
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.
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: 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.
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 are ready to compile the samples by running the verification scripts.
To verify the installation and compile two samples, run the verification applications provided with the product on the CPU:
car.pngimage in the demo directory. When the verification script completes, you will have the label and confidence for the top-10 categories:
Run the Inference Pipeline verification script:
This verification script builds the Security Barrier Camera Demo application included in the package.
This verification script uses the
car_1.bmp image in the demo directory to show an inference pipeline using three of the pre-trained models. 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 verification script completes, you will see an image that displays the resulting frame with detections rendered as bounding boxes, and text:

You have completed all required installation, configuration and build steps in this guide to use your CPU to work with your trained models. To use other hardware, see Install and Configure your Compatible Hardware below.
Install your compatible hardware from the list of supported components below.
NOTE: Once you've completed your hardware installation, you'll return to this guide to finish installation and configuration of the Intel® Distribution of OpenVINO™ toolkit.

Now that you've completed installation and configuration of your compatible hardware, you're ready to move to accelerator setup and run a sample application.
fpga_support_files.tgz are required to ensure your accelerator card and OpenVINO™ work correctly, and provide support for all compatible hardware accelerators.

If you have the Intel® Movidius™ Neural Compute Stick or Intel® Neural Compute Stick 2, plug it in now.
You have completed the accelerator installation and configuration. You are ready to run the Classification Sample, which you have compiled by running the Image Classification verification script in the Run the Verification Scripts to Verify Installation section.
IMPORTANT: This section requires that you have Run the Verification Scripts to Verify Installation.
Setting up a neural network is the first step in running a sample.
NOTE: If you are running inference only on a CPU, you already have the required FP32 neural network model. If you want to run inference on any hardware other than the CPU, you’ll need an FP16 version of the model, which you will set up in the following section.
Set Up a Neural Network Model
In this section, you will create an FP16 model suitable for hardware accelerators. For more information, see the information about FPGA plugins in the Inference Engine Developer Guide.
squeezenet1.1.labelsfile contains the classes that ImageNet uses. This file is included so that the inference results show text instead of classification numbers. Copy
squeezenet1.1.labelsto your optimized model location:
Once your neural network setup is complete, you're ready to run a sample application.
Run a Sample Application
HETERO:to your target:
NOTE: The CPU throughput is measured in Frames Per Second (FPS). This tells you how quickly the inference is done on the hardware.
The throughput on the accelerator may show a lower FPS due to the initialization time. To account for that, use
-ni to increase the number of iterations. This option reduces the initialization impact and gives a more accurate sense of the speed the inference can run on the accelerator.
