mentianyi · 2019-11-21T05:38:26Z

rp3b+,same error.

saifsmailbox98 · 2019-11-21T18:26:39Z

Same error using Raspbian Buster

saifsmailbox98 · 2019-11-21T18:52:19Z

Tried this workaround:

$ LD_PRELOAD=/usr/lib/arm-linux-gnueabihf/libatomic.so.1.2.0 python3 Object_detection_picamera.py  --usbcam

Getting a new error now:

Traceback (most recent call last):
  File "Object_detection_picamera.py", line 27, in <module>
    import tensorflow as tf
ModuleNotFoundError: No module named 'tensorflow'

Not sure if they are relevant.

Edit: Not relevant. The workaround should work.

mentianyi · 2019-11-22T08:56:20Z

No help..

saifsmailbox98 · 2019-11-22T17:35:35Z

Getting the same error?

Zach-OP · 2019-11-22T20:01:17Z

I'm seeing this as well.

Zach-OP · 2019-11-22T20:20:50Z

Hey, this is because the latest version of openCV doesn't work with RPi. Instead of pip3 install opencv-python try pip3 install opencv-python==3.4.6.27
You will need to uninstall the latest version first. pip3 uninstall opencv-python

happy-little-zhang · 2019-11-24T07:32:03Z

i used another way to solve this issue yesterday, but it's not convenient
i first install opencv follow other guidence
https://www.pyimagesearch.com/2019/09/16/install-opencv-4-on-raspberry-pi-4-and-raspbian buster/ ,
then i skep the step of installing opencv in this guidence .
the result is i need to execute some extra code everytime i run the "Object_detection_picamera.py", they are :

sudo find / -type f -name ‘atom.so*’
LD_PRELOAD=/usr/lib/arm-linux-gnueabihf/libatomic.so.1.2.0 python3 Object_detection_picamera.py

happy-little-zhang · 2019-11-24T07:36:38Z

i tried your way today , and it did works .
thank you for taking the time to solve this issue @Zach-OP

It worked for me on RPI 3 B. It uninstalled my opencv_python-4.1.1.26 now it's ok with opencv-python==3.4.6.27.
Thanks a lot !

svsadafule · 2020-02-27T04:30:52Z

Use OpenCV contrib with the right version.

pip install opencv-contrib-python==4.1.0.25

bharath-velisala · 2020-02-27T18:39:19Z

Did you solve this? I have same issue

Martink-NZ · 2020-04-04T03:45:13Z

I tried Zac's approach to uninstall and then install OpenCV. I tried using LD_PRELOAD. I tried using VIRTUALWRAPPER_PYTHON. I tried mkvirtualenv cv2. None of them worked.
I use Pi 4, 4GB and Intel Movidius NCS2, Python 3.7. Any other suggestions are much appreciated. This has taken much too much time to get resolved. Hopefully there is an easy solution.
Many thanks, Martin from NZ

I am also getting the same issue on rpi 4 . Someone plz help

shubhamkhandhar · 2020-05-03T11:04:45Z

Did you found any solution please post it

60999 · 2020-05-06T09:01:24Z

$ vi .bashrc (or nano .bashrc under root)
add：export LD_PRELOAD=/usr/lib/arm-linux-gnueabihf/libatomic.so.1
exit with save file.
$ source .bashrc
$ python3
Python 3.7.3 (default, Dec 20 2019, 18:57:59)
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

It will work.

yoher · 2020-05-14T01:02:30Z

Update following @Zach-OP advice to stay away from the latest version:
On a Pi4 today :

OpenCV 4.1.1.26 KO
OpenCV 4.1.0.25 imports properly and seems to run fine so far
=> Install with pip3 install opencv-python==4.1.0.25

shubhamkhandhar · 2020-05-15T07:53:47Z

Dear Sir, I have tried both the ways you have suggested me, but it seems none of them to be working, i am attaching the screeshots of the rpi terminal, od_problem_1) - It shows that the code doesn't run with sudo command. od_problem_2) - It shows that the code does run without sudo command. I am calling this code using another code which requires administrative rights for working as it contains flask api to connect to another api in another computer/laptop, so sudo needs to put there before working. please help.
