我有eth0，eth 1和wlan 0连接到我的树莓派。我想测量不同接口的互联网速度，在这种情况下-eth 1。它在eth0（192.168.1.21）上工作得很好，但是如果我尝试使用不同的接口，在本例中是eth 1（192.168.8.100），我会得到一个错误。
我阅读了Speedtest python API文档，大部分代码都是从那里复制的。我也试着在StackOverflow上发帖之前搜索。

source = "192.168.8.100" #eth1
s = speedtest.Speedtest(source_address=source)
s.get_servers()
s.get_best_server()
s.download()
s.upload()
res = s.results.dict()
download = res["download"]
upload = res["upload"]
ping = round(res["ping"])
print(download, upload, ping)

编辑：这是错误：
