I started to work with intel RealSense devices which uses pyrealsense2 python library. After installing that library with a great effort on Ubuntu, I also install opencv and numpy libraries. Since these libraries contain many many functions, autocompletion plays a big role.
However, it does not work for me with some libraries. For example, in VSCode and PyCharm, autocompletion for numpy library works well but for cv2 & pyrealsense2 it does not.
numpy was installed with pip, pyrealsense2 was installed from source and cv2 was installed with both pip and PyCharm packages.
I searched it for a long time but did not find a useful answer. If you want additional information don't hesitate to ask, please.
