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

Can you please help me to resolve this issue?
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.

I have been unable to connect to io.adafruit by mqtt, and I wonder if it is the minimqtt library. I am using the stock example code on github.
Example code: here
Board: Adafruit Esp32-S2 Feather
Firmware: CircuitPython 7.3.2
Secrets File:

'password' : '[deleted]',
'aio_username' : '[deleted]',
'aio_key' : '[deleted]',

'broker' : 'io.adafruit.com',
'port' : 1883
}
Output:

I was having similar errors using the Unexpected Maker ESP32-S2 as well.

I am running homeassistant in a docker container on a RPi 4 with Raspbian. I am using tributs scripts to elevate the need of running the docker image as root. This all works dandy. But now I am trying to add the dsmr integration but I am not succeeding. The integration requires to connect to the "Slimme meter" via USB. However, I get a permission error. my knowledge of both docker and linux privelages is too limited to know where to start debugging this. Does anyone have some pointers for me?
This is the error message homeassistant is throwing at me:

After some researching I figured that I needed to add the user to an extra group named dialout because only members of that group are allowed to access the USB ports (as well as other devices).
First I figured out the group id of the dialout group in the host machine (the machine running the docker container) by running
cat /etc/group | grep dialout
it returned 20 in my case. Luckily, the script of tributs has the possibility to add the user to an extra group via the environment variable EXTRA_GID. So all the relevant lines in the docker-compose file for accessing USB are (when using the script of tribut) are:
devices:
- /dev/ttyUSB0:/dev/ttyUSB0
environment:
- PUID=1000
- PGID=1000
- EXTRA_GID=20 # this is the ID of the group 'dialout'
I recently purchased a used dev board to start working on. I managed to flash it with Mendel 5 (Eagle) enabled SSH and followed the instructions on the get started without any issue until I tried the demo.
I can't get it to work at all!
If I run edgetpu_demo --stream
I get:

Which seems closer but no idea how to fix either. I've searched as much as I can (added the user the plugdev, made sure everything was installed correctly)
Any ideas? Pretty sure if this doesn't work something is fairly broken.
Thanks for reaching out, this is definitely not a good sign..

Sounds like the board some how lost access to the edgetpu, could you send us an email to coral-support#google.coon this issue?
I'm trying to start a dask cluster over SSH, but I am encountering a strange errors like these:
Exception in thread Thread-6:

I'm starting the cluster like this:
$ dask-ssh --ssh-private-key ~/.ssh/cluster_id_rsa \
--hostfile ~/dask-hosts.txt \
--remote-python "~/miniconda3/bin/python3.6"
My dask-hosts.txt looks like this:
localuser#127.0.0.1
remoteuser#10.10.4.200
...
remoteuser#10.10.4.207
I get the same error with/without the localhost line.
I have checked the ssh setup, I can login to all the nodes using a public key setup (the key is unencrypted, to avoid decryption prompts). What am I missing?
The error indicates that name resolution is the culprit. Most likely this is happening because of the inclusion of usernames in your dask-hosts.txt. According to its documentation, the host file should contain only hostnames/IP addresses:
–hostfile PATH Textfile with hostnames/IP addresses
You can use --ssh-username to set a username (although only a single one).
When i run this script from user jenkins (Linux Mint) i get this error, and when running it from my user it works. Jenkins user is created with jenkins service. I have installed virtualenv.

When you're logged in as yourself, you need to do echo $DISPLAY and note the display info it prints. Subsequently when you login as jenkins service you need to do xhost +, DISPLAY=[display-info]; export DISPLAY. (display-info is what you got from echo $DISPLAY, ignore the square brackets, they shouldn't be specified in the command)
Hopefully this should work. I don't have similar env to test, just mentioning what i recollect having done it quite sometime back.
