Hi Kevin, how did you resolve this error? I have exactly the same problem.

I am facing the same proble, has anyone figured it out ?

@gkrisp98 change face_ssd.py line 345 to:

         # output = self.detect(
               #   face_loc.view(face_loc.size(0), -1, 4),         # loc preds
               #   self.softmax(face_conf.view(face_conf.size(0), -1, self.num_classes)), # conf preds
               #   self.priors.type(type(x.data))                  # default boxes
               # )
