模块mtrpacket没有属性MtrPacket

Question

这是我在ubuntu机器上尝试的程序：

from operator import itemgetter

max(h, key=itemgetter('high'))

当我尝试运行时，它发出如下错误：

import asyncio
import mtrpacket

async def trace():
    async with mtrpacket.ProbeResult() as mtr:
        for ttl in range(1, 256):
            result = await mtr.probe('google.com', ttl=ttl)
            print(result)

            if result.success:
                break

asyncio.get_event_loop().run_until_complete(trace())

请让我知道如何解决此问题

我也尝试过：

avproxy@ubuntu:~$ sudo python3 mtrpacket.py
Traceback (most recent call last):

    import mtrpacket
