Coral Dev Board Windows 10 setup - google-coral

Question

I followed the windows host instructions described in the https://coral.ai/docs/dev-board/get-started/
When I run command mdt devices, I get following exception always:
$ mdt devices
Traceback (most recent call last):

OSError: [WinError 10049] The requested address is not valid in its context
Versions of my set up:
$ python --version
Python 3.8.5
$ mdt version
MDT version 1.5.2
Can you please help me to resolve this issue?

Answer 1

The same happened to me. Skipping some IP addresses solved the issue. Try this code:
import logging
import zeroconf
import ifaddr
for adapter in ifaddr.get_adapters():
print("IPs of network adapter ", adapter.nice_name)
for ip in adapter.ips:
print(" %s/%s", ip.ip, ip.network_prefix)
logging.basicConfig(level=logging.DEBUG)
logging.getLogger("zeroconf").setLevel(level=logging.DEBUG)
z = zeroconf.Zeroconf()
From the log, find
INFO:zeroconf:Address not available when adding XXX.XXX.XX.XX to multicast group, it is expected to happen on some systems
Along with the Zeroconf log, there should be a list of ip addresses and names. Please find the name of the hardware that is causing the problem.
Now, open zeroconf/__init__.py and goto get_all_addresses() and replace the code with below
adapters = [x for x in ifaddr.get_adapters()
if not "Microsoft Wi-Fi Direct Virtual Adapter" in x.nice_name
and not "Bluetooth Device" in x.nice_name]
return list(set(addr.ip for iface in adapters for addr in iface.ips if addr.is_IPv4))
Please replace the "Microsoft Wi-Fi Direct Virtual Adapter" and "Bluetooth Device" with the appropriate name.
This is not a neat way, so I'd be open to better answers.
