I followed a tutorial online for installing opencv4 on raspberry pi. Everything works except when trying to create a symbolic link to my cv2.so.
It appears to be working but I can only import cv2 module inside the /usr/local/python/cv2/python-3.7 directory if I'm outside, I get the :

ModuleNotFindError" no module named "cv2"

  • A Python module is more than just a shared library, there's also an __init__.py file and some config and loader files. Manually linking to the shared library is the wrong approach. The name of the shared library is also wrong, it should contain the Python version and the architecture, for example: /usr/local/lib/python3.8/site-packages/cv2/python-3.8/cv2.cpython-38-aarch64-linux-gnu.so. Usually, if you compile OpenCV from source and then make install, it is installed correctly as a Python module, why are you doing it manually? Please link to the tutorial you followed. – tttapa Mar 22 at 15:22
  • I don't have site-packages only "dist-packages": /usr/local/lib/python3.7/dist-packages $ ls pip pip-20.0.2.dist-info the tutorial: pyimagesearch.com/2018/09/26/… – Kungbjucha Mar 23 at 6:48
