Neural Network Models Installation

To detect and identify faces and face features (gender, age, emotions, beard, glasses, etc.), findface-extraction-api uses neural networks.

The neural networks models are automatically installed only if you opt for the FindFace Security standalone installation from installer. In all other cases, you have to manually initiate the models installation. Do the following:

  • During the step-by-step deployment, just follow the instructions.

  • If you have installed the apt repository from installer, install the models from installer as follows:

    1. Execute the prepared file.

      sudo ./
    2. Select a FindFace Security component to install: findface-data.

    3. Select models to install. After that, the installation process will automatically begin.


You can find installed face recognition models at /usr/share/findface-data/models/face/, face features recognition models at /usr/share/findface-data/models/faceattr/.
