JTOP showing different opencv version #2

Closed rsingh2083 closed 3 years ago

rsingh2083 commented 3 years ago

I compiled opencv with cuda support but while python3 is showing opencv version as 3.3.1, JTOP is showing opencv as Opencv : 4.1.2 compiled CUDA : YES

Any explanation as to what could be happening ? I was able to run the mask detection with average FPS of 25 for single face on webcam. But just puzzled about mismatch between jtop and python's opencv verions.

JTOP uses the package version you just installed (4.1.2) Python3 shows you the previous version (3.3.1) you probably forgot to uninstall before installing 4.1.2.. To avoid version conflicts, you must remove the old (3.3.1) version from your Nano. Please find the python OpenCV library by using the next commands:

$ python3
>>> import cv2
>>> cv2.__file__

Remove this file with sudo rm. Finish with sudo apt-get update Next go to your OpenCV build directory and re-run 

$ cd ~/opencv/build/ #(or something)
$ sudo make install  
$ sudo ldconfig
$ sudo apt-get update

If everything went well, you have now 4.1.2 also as Python version.
