Traceback (most recent call last):

File "/Users/loc/DECA/demos/demo_reconstruct.py", line 40, in main
testdata = datasets.TestData(args.inputpath, iscrop=args.iscrop, face_detector=args.detector, sample_step=args.sample_step)

self.face_detector = detectors.FAN()
File "/Users/loc/DECA/decalib/datasets/detectors.py", line 28, in init
out = self.model.get_landmarks(image)

How should I set this "image" value?
I get an error when I directly use the content from the comments.
