Neural Network Models Installation

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

If you have to manually initiate the models installation, use the console installer as follows:

  1. Execute the prepared file.

    sudo ./
  2. Select the installation type: Fully customized installation.

  3. Select a FindFace Security component to install: findface-data. To do so, first deselect all the listed components by entering -* in the command line, then select the required component by entering its sequence number (keyword): 1. Enter done to save your selection and proceed to another step.

  4. In the same manner, 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/.
