在scheduler中加了multiproces之后，download 和 md5_list都变成了 multiprocess的 method，无法正常往下执行。

  # multiprocess
    from pdb import set_trace
    set_trace()
    scheduler.set_cal_type(CalcType.MultiProcess)
    multiprocess_time = scheduler.process()

Traceback (most recent call last):
  File "/usr/local/study_process/download_server/scheduler.py", line 119, in <module>
    multiprocess_time = scheduler.process()
  File "/usr/local/study_process/download_server/scheduler.py", line 51, in process
    for md5 in md5_list:
TypeError: 'method' object is not iterable
