Deep Learning Workbench (DL Workbench) is a platform built upon OpenVINO™ and provides a web-based graphical environment that enables you to optimize, fine-tune, analyze, visualize, and compare performance of deep learning models on various Intel® architecture configurations. In the DL Workbench, you can use most of OpenVINO™ toolkit components:
Proceed to an easy installation from Docker to get started.
NOTE: With OpenVINO™ 2020.4 release, Intel® Movidius™ Neural Compute Stick is no longer supported.
NOTE: If you want to use Microsoft Visual Studio 2019, you are required to install CMake 3.14.
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.
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: If you installed the Intel® Distribution of OpenVINO™ to the non-default install directory, replace
C:\Program Files (x86)\Intelwith 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:
(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.
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.
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
<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)\Intelwith the directory where you installed the software.
These steps use a command prompt to make sure you see error messages.
Open a command prompt. To do so, type
cmd in your Search Windows box and then press Enter. Type commands in the opened window:
The Model Optimizer is configured for one or more frameworks. Success is indicated by a screen similar to this:
