It seems that it's because the face pictures I provided in data/facebank folder are not good enough. As you can see, for these 2 pictures above, the one with helmet can cause error while the one without helmet works fine

How did you solve it? @AndyTesla

[AndyTesla]

@THIlangarathna maybe try to make your face picture better. As you can see in my case, make your face get a greater portion in your picture. Maybe The second picture has too much unnecessary thing like helmet, background that can cause error
