divmod出错

Question

尝试运行一些代码。我这样做时会出现此错误。我以为我安装了所有必需的依赖项，但仍然遇到此错误。

的Linux; GNU C ++版本4.8.1; Boost_105300; UHD_003.007.000-133-g6bd9fed2

Traceback (most recent call last):
  File "/usr/local/bin/tpms_rx", line 274, in <module>
    main()
  File "/usr/local/bin/tpms_rx", line 265, in main
    tb = top_block(source, args)
  File "/usr/local/bin/tpms_rx", line 229, in __init__
    self.source = source_rtlsdr(args.tuned_frequency, args.if_rate)
  File "/usr/local/lib/python2.7/dist-packages/tpms/source.py", line 98, in __init__
    rf_decimation, rf_decimation_remainder = divmod(rf_sampling_rate, if_sampling_rate)
TypeError: unsupported operand type(s) for divmod(): 'int' and 'NoneType'

Answer 1

运行程序时，您需要传递参数-i / --if-rate，否则默认值为None，最终会在2层之后传递给divmod
