I haven't provided armv7a wheels due to this issue which I reported 3 weeks ago: https://github.com/google/ruy/issues/347

Your best bet is to clone tensorflow and try to build it for armv7a and when it fails raise an issue with the tensorflow project.

Or try to fix it in Ruy yourself ;)

[StefanoGiu]

I don't have an ARMv7 processor... I have an Intel i3 octacore... 64 bit... Why I enter into the ARMv7 path?

[oberluz]

Please paste the commands you are using to build it

[StefanoGiu]

I tried both with scripts/build.sh and scripts/build_deb.sh.

I'm on Linux Mint 21

[oberluz]

Can you paste the command you are using?

If you are using just scripts/builds.sh then you will be building all python versions for all archs, including arm7a

[StefanoGiu]

I'm using "scripts/build.sh"... this is the command... what shall I use?

[oberluz]

What arch / python version are you after?

I'm on Python 3.10.12 and x86_64 arch.

[oberluz]

Why don't you use the wheels already provided in the releases?

$ python --version

You can build it yourself with:

$ git checkout 2_7_0 # or 2_14_0
$ git submodule update --init --recursive
$ DOCKER_CPUS=k8 scripts/build.sh --python_versions 310

Note in scripts/build.sh that 310 is built using ubuntu:22.04. If you get an error message when installing the wheels due to libc you could try changing ubuntu:22.04 to use a docker image for your linux mint release.

[StefanoGiu]

Sorry, where can I get those whl files?

[oberluz]

Look in the main page on the right there is a link called releases.

It points to https://github.com/oberluz/pycoral/releases

[StefanoGiu]

Thanks a lot!! I installed it, but now when I run:

root@ServerNVR:/home/stefano/coral/coral/pycoral# 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

I get the following error: Traceback (most recent call last): File "/usr/local/lib/python3.10/dist-packages/tflite_runtime/interpreter.py", line 166, in load_delegate delegate = Delegate(library, options) File "/usr/local/lib/python3.10/dist-packages/tflite_runtime/interpreter.py", line 104, in init raise ValueError(capture.message) ValueError

During handling of the above exception, another exception occurred:

Can you help here?

[oberluz]

Paste the relevant code...

[StefanoGiu]

I'm following this link: https://coral.ai/docs/accelerator/get-started/#3-run-a-model-on-the-edge-tpu

[StefanoGiu]

I'm trying to run: 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

[oberluz]

Did you plugin in your coral stick into the USB port?

I ran it without the coral and I got the same error:

I plugged it in and it works:

eyeot-demo@eyeotdemo-ThinkPad-X380-Yoga:~/src/pycoral/tmp(2_7_0)$ python3.8 ../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

[StefanoGiu]

Yes, it's plugged in, but used by Frigate in a container. Maybe Frigate is locking the USB Coral somehow?

[StefanoGiu]

Any idea? The issue seems to be intermittent and sometimes I get a segmentation fault... with a core dump!

[StefanoGiu]

I tried to stop Frigate, but the issue is still there...

[oberluz]

I can't give you any advice re Frigate.

Try it outside is all I can suggest

I tried outside Frigate container... it's the same...
