RuntimeError: Error in device opening about google-coral

[mrusme]

@habakan your user is not in the correct set of groups that allow access to the device. Either add your user to the correct group or run as root.

@mrusme
Thank you comments.
I ran as root, but the same error happened.

[langersteff]

Same here unfortunately. Has anyone found a fix yet?

[dksim]

Try
sudo usermod -aG plugdev YOURUSERNAME
and reboot

@dksim
Thank you.
I tried it but it was same error...
I contacted coral-support team about this problem.
I received a reply "We do not officially support USB Accelerator with Jetson TX2 as of now" .

I'm on the same platform (TX2) and following https://coral.withgoogle.com/docs/edgetpu/api-intro/ (which looks like the same example). I originally had this same error and after following @dksim am able to run on the USB edgeTPU from Jetson:

$ cd /usr/share/edgetpu/examples/
$ python3 classify_image.py --model models/mobilenet_v2_1.0_224_inat_bird_quant_edgetpu.tflite --label models/inat_bird_labels.txt --image images/parrot.jpg

Thank you comments!
I confirmed to run by your and @dksim's method!
It seems my method of installation is different from in your provided url.

I installed following script. This Script is failed to run.

$ wget https://dl.google.com/coral/edgetpu_api/edgetpu_api_latest.tar.gz -O edgetpu_api.tar.gz --trust-server-names
$ tar xzf edgetpu_api.tar.gz
$ cd edgetpu_api
$ vim install.sh
$ sudo edgetpu_api/install.sh

By reinstall using this method, I can run on EdgeTPU Accelarator!

echo "deb https://packages.cloud.google.com/apt coral-edgetpu-stable main" | sudo tee /etc/apt/sources.list.d/coral-edgetpu.list

curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -

sudo apt-get update

sudo apt-get install python3-edgetpu

Thanks for everyone!
