Cant Pre-train

[Rubseena]

In model.py

def create_models(buckets = [25, 50, 100], phase = caffe.TRAIN):

  transformers = create_spatial_transformers(buckets, phase)
  proposal_net = create_yolo(phase)
  recog = create_recognizer(phase)

  return proposal_net, transformers, recog

Here in this method, create_spatial_transformers() create_yolo() create_recognizer() these three function showing error because these three function not defined in the entire project. How can I get the full code of that function

Thanks in Advance
