Description

Hi all

I try to run on my raspi the image classifier example with the bird photo and get the error no module named 'pycoral.pybind._pywrap_coral'. Can someone help me please? image

I did all the steps of this installation guide: https://coral.ai/docs/accelerator/get-started

All installations were successfully done.

Info: -Raspberry Pi 3B -Python 3.5

Thanks for help!

Hello @saga0611 pycoral module works with Python 3.6, 3.7, 3.8, or 3.9 versions only. Please upgrade the python version and try the demo.

Hi @hjonnala

Thanks for your help!

I installed python 3.8 now but I get a similar error: No module named 'pycoral.adapters'. Do you have an other hint? image

hjonnala commented 2 years ago

Please check the pycoral version got installed and try the command as a super user.

sudo 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

Python 3.9.7 (default, Sep  3 2021, 06:18:44)

saga0611 commented 2 years ago

Here the version check of pycoral:

pi@eee-00433:~/Desktop/coral/pycoral $ python3.8
Python 3.8.4 (default, Dec 24 2021, 15:23:21) 
[GCC 6.3.0 20170516] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pycoral
>>> pycoral.__version__
'2.0.0'

I tryed with "sudo" but unfortunately without success. Now with "sudo" I get this error:

sudo 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
Traceback (most recent call last):
  File "examples/classify_image.py", line 37, in <module>
    from pycoral.adapters import classify
ModuleNotFoundError: No module named 'pycoral'

Do you maybe know why I get this error although the installation of pycoral seems okay?

hjonnala commented 2 years ago

hmm.. Have you uninstall and install the pycoral after upgrading the python version?

Can please try to uninstall pycoral sudo apt-get purge python3-pycoral and install the pycoral using this command sudo apt-get install python3-pycoral and try the demo.

If this is not working please uninstall pycoral and install it using pip and try the demo. Thanks!

python3.8 -m pip install --extra-index-url https://google-coral.github.io/py-repo/ pycoral~=2.0

saga0611 commented 2 years ago

I unistalled pycroal and installed it with sudo apt-get install python3-pycoral but the example was still not working (same error as before).

With this command python3.8 -m pip install --extra-index-url https://google-coral.github.io/py-repo/ pycoral~=2.0 I get this installation error:

Pillow seems to be a problem...

Hi @hjonnala

I set up my raspi new and now it works. I don't know what was wrong with the system before.

Anyway thank you very much for your help!
