failed to load delegate - aarch64, Debian
Description
Trying to run the initial example:
tgall@viper:~/coral/pycoral-examples$ python3 examples/classify_image.py --model test_data/mobilenet_v2_1.0_224_inat_bird_quant_edgetpu.tflite --labels test_data/inat_bird_labels.txt --input test_data/parrot.jpg Traceback (most recent call last): File "/home/tgall/.local/lib/python3.7/site-packages/tflite_runtime/interpreter.py", line 160, in load_delegate delegate = Delegate(library, options) File "/home/tgall/.local/lib/python3.7/site-packages/tflite_runtime/interpreter.py", line 119, in init raise ValueError(capture.message) ValueError
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "examples/classify_image.py", line 121, in
applying some of the common things to looking at:
tgall@viper:~/coral/pycoral-examples$ python3 -c "from ctypes.util import find_library; print(find_library("edgetpu"))" libedgetpu.so.1
tgall@viper:~/coral/pycoral-examples$ lsusb -d 1a6e:089a Bus 001 Device 004: ID 1a6e:089a Global Unichip Corp.
I had made sure to add my userid into plugdev with sudo usermod -aG plugdev
likewise looking at udev rules /etc/udev/rules.d/ I have tgall@viper:~/coral/pycoral-examples$ cat /etc/udev/rules.d/99-edgetpu-accelerator.rules SUBSYSTEM=="usb",ATTRS{idVendor}=="1a6e",GROUP="plugdev" SUBSYSTEM=="usb",ATTRS{idVendor}=="18d1",GROUP="plugdev"
and from dmesg : [210360.152395] usb 1-1: new high-speed USB device number 3 using ehci-pci [210360.307907] usb 1-1: New USB device found, idVendor=1a6e, idProduct=089a, bcdDevice= 1.00 [210360.307908] usb 1-1: New USB device strings: Mfr=0, Product=0, SerialNumber=0 [214202.364639] usb 1-1: USB disconnect, device number 3 [214221.585606] usb 1-2: new high-speed USB device number 4 using ehci-pci [214221.744194] usb 1-2: New USB device found, idVendor=1a6e, idProduct=089a, bcdDevice= 1.00 [214221.744196] usb 1-2: New USB device strings: Mfr=0, Product=0, SerialNumber=0

Can you please try below commands and after replacing the libedgetpu path in the following commands and try the demo.
sudo chmod +rwx /usr/lib/aarch64-linux-gnu/libedgetpu.so.1.0
sudo chmod +rwx /usr/lib/aarch64-linux-gnu/libedgetpu.so.1
Ok tried and re-ran the example. Same error from what I can tell

can you please share how did you install libedgetpu runtime and output of following snippet. Thanks!
mog@random:~$ python3 -c 'from pycoral.utils.edgetpu import get_runtime_version; print(get_runtime_version())'
BuildLabel(COMPILER=6.3.0 20170516,DATE=redacted,TIME=redacted), RuntimeVersion(14)
Here is my output:
tgall@viper:/usr/include$ python3 -c 'from pycoral.utils.edgetpu import get_runtime_version; print(get_runtime_version())' BuildLabel(COMPILER=6.3.0 20170516,DATE=redacted,TIME=redacted), RuntimeVersion(14)
and for libedgetpu I used apt-get
tgall@viper:~$ dpkg -s libedgetpu1-std Package: libedgetpu1-std Status: install ok installed Priority: optional Section: misc Installed-Size: 1130 Maintainer: Coral [email protected] Architecture: arm64 Multi-Arch: same Source: libedgetpu Version: 16.0 Provides: libedgetpu1 (= 16.0) Depends: libc6, libgcc1, libstdc++6, libusb-1.0-0 Conflicts: libedgetpu1, libedgetpu1-legacy Description: Support library for Edge TPU Support library (standard speed) for the Edge TPU Homepage: https://coral.ai/
Okay, can you please share the output of following snippet. Thanks https://github.com/google-coral/edgetpu/issues/491#issuecomment-948206410
I am running the code in raspberry PI 4 and facing the same issue. Any suggestion?

If you are using the usb accelerator, and it its plugged to your computer, setting the following udev rules should work:
foo@bar:~$ lsusb -d 1a6e:089a
Bus 002 Device 004: ID 1a6e:089a Global Unichip Corp.
foo@bar:~$ echo 'SUBSYSTEMS=="usb", ATTRS{idVendor}=="1a6e", ATTRS{idProduct}=="089a", MODE="0664", TAG+="uaccess"' | sudo tee -a /etc/udev/rules.d/71-edgetpu.rules > /dev/null
foo@bar:~$ echo 'SUBSYSTEMS=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="9302", MODE="0664", TAG+="uaccess"' | sudo tee -a /etc/udev/rules.d/71-edgetpu.rules > /dev/null
foo@bar:~$ sudo udevadm control --reload-rules && sudo udevadm trigger
