Lot's of information is printed when running face detection script

When I run the following simple script a lot of data is printed in the terminal:

import bob.io.base
import bob.io.base.test_utils
import bob.io.image
import bob.ip.mtcnn

color_image = bob.io.base.load(bob.io.base.test_utils.datafile('testimage.jpg', 'bob.ip.facedetect'))

bounding_box = bob.ip.mtcnn.FaceDetector().detect_single_face(color_image)

An example of terminal output (just the last 5 lines):

@tiago.pereira, do you have an idea why is this happening? Thank you!
