pre-trained model size mismatch

[caozhangjie]

Hi Hsin Ying Lee,

The pre-trained model has 24 output but the model in train_opn.prototxt has only 12 output. I think that 4 images have 24 orders and thus the number of orders should be 24. Thus the 12 orders in train_opn.prototxt and UCF_datalayers.py may be wrong.
