Once you notice that the model status (indicated at the upper-right of the Default Custom Model page) has changed to Model is ready to train, you can then click on the Train Model button to start training the Face model on the training images we provided:

Since we provided only roughly 30 training images, the training process should take less than 5 or 10 minutes. During the training, you will not be able to make any changes to the model or classes.
