fix: cv2.error: OpenCV(3.4.2) 'function not implemented' issue in conda environment files #27

Open SS47816 opened 3 years ago

Hi,

I experienced a dependency issue while running the object_tracker.py, the cvShowImage function seems to have an error in openCV 3.4.2

cv2.error: OpenCV(3.4.2) /tmp/build/80754af9/opencv-suite_1535558553474/work/modules/highgui/src/window.cpp:632: error: (-2:Unspecified error) The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function 'cvShowImage'

I was running the code on Ubuntu 18.04 machine with Nvidia GPU

I fixed this by installing openCV 4.1.0:

conda remove opencv
conda install -c conda-forge opencv=4.1.0

Hence, I modified the conda-cpu.yml and the conda-gpu.yml files to use conda-forge channel with openCV 4.1.0 on the lists.

Hope this will help the rest trying this code.

Best regards, SS
