No module named 'pycoral.pybind._pywrap_coral' (aarch64, debian bullseye, python 3.9)

[leoniloris]

Hello folks!
So, I have the following system

debian bullseye
python 3.9
architecture aarch64 (arm64 or armv8)

after some time struggling, I compiled manually and generated the both tflite and pycoral for my board, installed them both and I'm trying to follow https://coral.ai/docs/m2/get-started/#4-run-a-model-on-the-edge-tpu
But I'm facing the following problem
ModuleNotFoundError: No module named 'pycoral.pybind._pywrap_coral'

I have no Idea what I did wrong. do you guys know?

[leoniloris]

Any news?

Having exactly the same issue... anyone?

I have something similar using python 3.7 on a raspberry pi4.

Traceback (most recent call last): File "test_coral.py", line 8, in <module> from pycoral.utils import edgetpu File "/home/pi/projects/coral/pycoral/pycoral/utils/edgetpu.py", line 24, in <module> from pycoral.pybind._pywrap_coral import GetRuntimeVersion as get_runtime_version ModuleNotFoundError: No module named 'pycoral.pybind'

I ran into a similar issue with pycoral. I believe it's because classify_image.py is confusing the pycoral package with the pycoral folder. I was able to resolve it by renaming the pycoral folder to something else.

@abelhouchat May I know on which platform you have this issue. Can you mention how you have installed python3-pycoral ?

[abelhouchat]

@Naveen-Dodda This is on Ubuntu 18.04. I installed pycoral as recommended in the tutorial, using sudo apt-get install python3-pycoral

[Naveen-Dodda]

Can you try a pip install instead

Hello, does anyone here still facing the issue. If yes, please let me know the python version and operating system have been used.

[maazullah96]

Solved the issue by installing through the whl file
https://coral.ai/software/#pycoral-api

[hjonnala]

@leoniloris are you able to fix the issue.

I'm still having the issue with Ubuntu 18.04 and python 3.8.8 (apt install -> ModuleNotFound) pip3 install from the instructions linked above worked

[maazullah96]

@mprhode Did you have tried the installation from whl file?

[japm48]

I had the exact same problem in Windows, and after hours of guessing/debugging I realised that I forgot to install the Edge TPU runtime (step 1 in the instructions...).
Note that, at least in my case, the "No module named" error is misleading: the pyd module is actually found but it fails to load because it cannot find some DLL/.so dependency (my candidates are libusb, UsbDk or libedgetpu). This can be debugged in Windows by loading with ctypes.WinDLL (possibly something similar with Linux).

Possibly related to #18 and #32. Oops... just read the last messages in there.

The issue(No module named 'pycoral.pybind._pywrap_coral') can be resolved using the whl files from this source : https://github.com/google-coral/pycoral/releases for python vesrions 3.5 - 3.8.

Thank you. I work for me.

ModuleNotFoundError: No module named 'pycoral.pybind._pywrap_coral'

If you get this error, its because there's a directory in the repo called pycoral. If you mv pycoral pycoral2 everything starts working. No need to downgrade Python.

Hi, I am having a similar problem.

When I enter step 3 from https://coral.ai/docs/accelerator/get-started/#3-run-a-model-on-the-edge-tpu I get error code:
Traceback (most recent call last):
File "examples/classify_image.py", line 37, in from pycoral.adapters import classify
ModuleNotFoundError: No module named 'pycoral'

I have downgraded to python 3.7.12 from 3.9.2 (RPi 4), running on arm7l 32-bit.
I have also tried installing the whl file and tried renaming the pycoral folder name to pycoral2 as suggested.

All have had no success. Any help on this?

I'm having the same issue. I can run the test on the host machine but when I run it in docker i get this same error. Did you get it working?
