Why the Facial Recognition Model I trained using the method you provided didn't work?

As article mentioned, we need build a facial recognition classifier first.

But as the picture shows, the FRT Loss didn't drop during training.

Thank you for your time and attention. I would appreciate it very much if you could give me a reply.

This is still the case when I increase the epoch to 500.
