Why do I need to uninstall opencv that came preinstalled on with nvidia Jetpack?

  File "/media/$USER/9C33-6BBD/yolov5/utils/dataloaders.py", line 472, in __next__
    if not all(x.is_alive() for x in self.threads) or cv2.waitKey(1) == ord("q"):  # q to quit
cv2.error: OpenCV(4.8.0) /io/opencv/modules/highgui/src/window.cpp:1338: error: (-2:Unspecified error) The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Cocoa support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function 'cvWaitKey'

I was trying to run yolov5 webcam detections, but the opencv is built without libgtk and I can’t see the windows.

What is stopping me from uninstalling the opencv ?

→ sudo apt purge libopencv-dev

Use 'sudo apt autoremove' to remove them.
The following packages will be REMOVED:
  libopencv-dev* nvidia-jetpack* nvidia-jetpack-dev* nvidia-opencv-dev*
0 upgraded, 0 newly installed, 4 to remove and 4 not upgraded.
After this operation, 7,084 kB disk space will be freed.

As you can see nvidia-jetpack nvidia-jetpack-dev would also be uninstalled along with libopencv

Questions:

  1. Can I only uninstall opencv from my AGX orin without removing other nvidia jetpack components?
  2. If I cannot (1), can I reinstall selected components without installing opencv after I’ve built my own version from source and other libraries included?

Hi,
Please try this command:
JEP/script/install_opencv4.6.0_Jetson.sh at master · AastaNV/JEP · GitHub

sudo apt -y purge libopencv
