Installing OpenVINO™ packages

During the ros-humble-openvino-node package installation you will be asked if you want to install the OpenVINO™ IR formatted models. Some of the OpenVINO™ based tutorials in this SDK rely on the models that are provided during the installation of the ros-humble-openvino-node.

It is important to answer this question with “yes”.

Configuring ros-humble-openvino-node
------------------------------------

The Intel OpenVINO™ toolkit provides a set of public models and Intel's pre-trained models in OpenVINO™ IR format (*.xml + *.bin) that you can use for learning and demo purposes or for developing deep learning on ROS2 node.

Do you want to download & convert OpenVINO™ IR formatted models [default=no]? [yes/no] yes

Note

In case you are facing issues running the tutorials because you failed to install the OpenVINO models:

  1. Cleanup OpenVINO by following the steps in OpenVINO™ Re-Installation and Troubleshooting.

  2. Reinstall OpenVINO following OpenVINO™ Installation Steps.

OpenVINO™ Installation Steps

  1. Make sure OpenVINO APT repository is configured

    wget -O- https://apt.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS.PUB | gpg --dearmor | sudo tee /usr/share/keyrings/openvino-archive-keyring.gpg
echo "deb [signed-by=/usr/share/keyrings/openvino-archive-keyring.gpg] https://apt.repos.intel.com/openvino/2023 ubuntu22 main" | sudo tee /etc/apt/sources.list.d/intel-openvino-2023.list
    Copy to clipboard

  2. Install get debconf utilities

    sudo apt install debconf-utils
    Copy to clipboard

  3. Clear any previous installation configurations

    echo PURGE | sudo debconf-communicate ros-humble-openvino-node
    Copy to clipboard

  4. Set/force the config option to True before installation of the package

    This step can’t be automated since it would violate licensing terms by not prompting, but if the user manually does the config it is probably fine.

    echo "ros-humble-openvino-node openvino-node/models boolean true" | sudo debconf-set-selections

sudo apt install ros-humble-openvino-node
