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
