Does this happen with other images as well?

no, only with this and few more

Printing faces.shape and getting 0 led me to conclude that the problem is with the face detector and not age or gender detection.

The image is very low quality, so the face detector model cannot find any faces on it.

simple solution is

faces, boxes, scores, landmarks = face_detector.detect_align(img)
if len(faces.shape) == 1:
    print("the model can't find any faces")
