something about face recognition

thanks for your great work. I run your code with A100 GPU, it works! I have some questions about model inference。
1. I train the face_emore datasets and get the .pth model. Now i want to recognize a video with the .pth and watch the effect as your video demon. As i know, I should use the .pth update the face database, then work on the test video. but i havenot found how to finish it. Hope to get your reply~
