ValueError: math domain error

你好，我在使用py-ios-device执行pyidevice instruments monitor命令时，出现如下的错误提示：

2021-10-09 11:08:04 [ERROR] [Instrument] dvt.py[line:247] math domain error
Traceback (most recent call last):
  File "c:\python36\lib\site-packages\ios_device\servers\dvt.py", line 234, in _receiver

  File "c:\python36\lib\site-packages\ios_device\cli\instruments.py", line 257, in on_callback_message
    print("Memory  >>", Memory.decode(data))
  File "c:\python36\lib\site-packages\ios_device\util\utils.py", line 211, in decode
    Swap_Used = convertBytes(system.get("__vmSwapUsage"))
  File "c:\python36\lib\site-packages\ios_device\util\utils.py", line 122, in convertBytes
    math.log(_bytes, 1024)  # 求对数(对数：若 a**b = N 则 b 叫做以 a 为底 N 的对数)
ValueError: math domain error

设备是iPhone 12 Pro，系统版本iOS 14.7.1 不太清楚为何会出现这种问题，还麻烦帮忙看看，谢谢。

Aborted!

C:\Users\MIco λ pip list | grep py-ios py-ios-device 2.3.32.2

2.3.32.2 版本仍存在该问，麻烦看下
