PyCoral on RPi Bullseye 32Bit (Python3.9)

[TimPearson]

Description

Failed to run examples (classify_image.py) on latest install RPi4 operating system (11 aka Bullseye) with error No module named 'pycoral.adapters'.

I suspect this is because it comes with python 3.9. (alternatively I have done something stupid and am an idiot)

I tried downgrading to 3.8 but got into version hell with NUMPy etc.

Hello @TimPearson Can you please share how did you install and the pycoarl and output of below snippet.

Python 3.9.7 (default, Sep  3 2021, 06:18:44) 
[GCC 10.2.1 20210110] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pycoral
>>> pycoral.__version__

Hello @hjonnala sure but i will have to recreate system as have since messed it up trying to find a fix, will try and get that done tomorrow.

From clean system: sudo apt install git sudo apt install python3-virtualenv sudo apt-get update 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 install libedgetpu1-std sudo apt-get install python3-coral mkdir coral cd coral git clone https://github.com/google-coral/pycoral.git cd pycoral virtualenv pycoralvenv source pycoralvenv/bin/activate bash examples/install_requirements.sh classify_image.py pip3 install pillow pip3 install numpy sudo apt-get install libatlas-base-dev 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

gives error finding pycoral on line 37 from pycoral.adapters import classify

Then if I ask version I get:

(pycoralvenv) pi@raspberrypi:~/coral/pycoral $ python3 Python 3.9.2 (default, Mar 12 2021, 04:06:34) [GCC 10.2.1 20210110] on linux Type "help", "copyright", "credits" or "license" for more information. import pycoral pycoral.__version__ '2.0.0'

[hjonnala]

can you try uninstallpython3-coral and install python3-pycoral (https://coral.ai/software/#debian-packages)

[TimPearson]

i was still getting errors. Turned out that simply giving myself root rights via sudo solved the problem - i have no idea why? so:

sudo 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

gives 👎 ----INFERENCE TIME---- Note: The first inference on Edge TPU is slow because it includes loading the model into Edge TPU memory. 129.3ms 15.2ms 15.9ms 16.0ms 15.7ms -------RESULTS-------- Ara macao (Scarlet Macaw): 0.75781

Just in case anybody runs into this, I got it working with Bullseye. Here are the details:

pi@raspberrypi:~/coral/pycoral $ python --version Python 3.9.2

pi@raspberrypi:~/coral/pycoral $ pip list Package Version

@crittercam you could have shared your cli commands so that others could repeat.
