Unable to Install Pycoral on Raspberry Pi 5

[minhtribui153]

Description

The latest version of raspbian os for raspberry pi 5 currently only supports Python 3.11, not Python 3.10 or newer. But for Pycoral to be installed, it requires Python 3.10 or newer. Is there any way that you can support Raspberry Pi 5?

This is the command I used to run:

sudo apt-get install python3-pycoral

tflite-runtime can be installed in my venv wirh "pip install tflite-runtime".

Now when I run "pip install pycoral" I get the following messages:

Okay, forget "tflite-runtime". This version would be too new anyway. pycoral requires 2.5.0.post1 and I now have 2.14.0

[hra42]

I just run pycoral in a docker container for now.. performance is good enoght for what I need to do.

Thanks!

As the documentation requests, I used Debian 10

Pycoral is basically abandoned. Using pyenv and python-3.9.18 I have gotten https://github.com/oberluz/pycoral fork to work. At least, after fixing a couple s/PIL.Image.ANTIALIAS/PIL.Image.LANCZOS/ breakages (the PIL version this pulls has removed ANTIALIAS), I can run the classify and detect_image examples to run. I haven't yet managed to get it to work with the model I'm trying (tf2_ssd_mobilenet_v2_coco17_ptq_edgetpu.tflite)

Support for EdgeTPu is coming back. Updated libcoral and pycoral libraries for Python 3.11+ and modern TF are coming. The libedgetpu official repo was just updated based on my PR, and is compatible with TF 2.15.0

I am working to get libcoral/pycoral merged to the stable repo by the time TF 2.16.0 reaches stable.
