Hi, I tried to reproduce the result.
And in the submission code. There is:

`from face_utils import norm_crop, FaceDetector
  File "/home/song/deepfake/kaggle-dfdc/face_utils.py", line 8, in <module>
    from layers.functions.prior_box import PriorBox
  File "/home/song/deepfake/kaggle-dfdc/layers/__init__.py", line 1, in <module>
    from .functions import pior_box
  File "/home/song/deepfake/kaggle-dfdc/layers/functions/__init__.py", line 1, in <module>
    from .detection import Detect
  File "/home/song/deepfake/kaggle-dfdc/layers/functions/detection.py", line 4, in <module>
    from data import voc as cfg
ImportError: cannot import name 'voc'

`
in your code, i can't find the layer folder. Is there anything missing?
