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:
shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
Press 'q' to quit.
Press 'n' to switch between models.
Traceback (most recent call last):

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 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 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 created an instance of the latest official odoo image with postgres behind and started using it. After recreation of the container due to odoo config changes I got a 404 on all assets after the recreation of the odoo container, which leads to an empty white page.
So at the moment I can't use odoo anymore.
Any ideas?
This is the output of the odoo container. I get a few of similar cache related exceptions:

I am using Python 3.7 with Appium 1.15.1 on real Android Device.
When my script finish the job, I close the driver with these lines:
if p_driver:
p_driver.close()
but I get this error ouput:

selenium.common.exceptions.WebDriverException: Message: An unknown server-side error occurred while processing the command. Original error: Could not proxy. Proxy error: Could not proxy command to remote server. Original error: 404 - undefined
I would like to understand what I am doing wrong?
What is the way to close properly the driver?
Can you help me please?
Step1: you should get the appium session dictionary first:
session_instance = webdriver.Remote(str(url), caps_dic)
where url is your appium server url. something like: "http://127.0.0.1:4723/wd/hub"
and caps_dic is a dictionary of all your desired capabilities
Step2: you run the quit() method on session:
session_instance[session].quit()
So the whole snippet is:
session_instance = webdriver.Remote(str(url), caps_dic)
session_instance[session].quit()
