step 1.
       freeze = False
       model_name = 'senet154'
       min_num_class = 10
       checkPoint_start = 0
       lr = 3e-4
       #until train map5 >= 0.98

step 2.
       freeze = True
       model_name = 'senet154'
       min_num_class = 0
       checkPoint_start = best checkPoint of step 1
       lr = 3e-4

step 3.
       freeze = True
       model_name = 'senet154'
       min_num_class = 0
       checkPoint_start = best checkPoint of step 2
       lr = 3e-5
