Looks like the correct paths are:
my_cascade = HaarFaceDetector("../etc/xml/haarcascade_frontalface_alt.xml", "../etc/xml/haarcascade_profileface.xml")
and .dat file in the next line from
wget dlib.net/files/shape_predictor_68_face_landmarks.dat.bz2
bzip2 -d shape_predictor_68_face_landmarks.dat.bz2

Thank you for pointing that out. I added a warning if the file dat is missing.
The path of the XML files has also been fixed.
