Describe the issue

Using your code and pretrained model located in PyimageSearch Starter Bundle chapter22-smile_detection I feeding self made video with my face smiling and not smiling intermittedly. The only label I see is "Not smiling" :-(
Can you provide a test video to see expected result? This could eliminate the case my smile is different and thus not detected ...
