问题
I have installed opencv 3.4.1 correctly on my system enviroment.
But after I create a conda virtual environment using a yml file inlcues opencv3.2.0, it leads some problems here:
Under the conda virtual env, I have to always first
cd PATH_TO_VIRTUAL_ENV/lib/python3.5/site_packages
such that import cv2 is correctly using the 3.2.0 version of opencv,without this step, 3.4.1 will be used.
Under the conda base environment , if the PATH in ~/.bashrc is added to anaconda3, then I will under conda base enviroment by default. import cv2 will use opencv 3.4.1 version.
Under the system enviroment, i.e first delete the PATH to anaconda3, then import cv2 will lead to segmentation fault.
It seems like the path variable has to be settled correctly, how could I solve this?
