I built the OpenCV4 by Cmake and installed the opecv4.0 using anaconda3 and its python3.7. My platform is Ubuntu 18.04 LTS. I can successfully use the OpenCV in terminal. But the PyCharm's project interpreter cannot find the opencv library, so I cannot use the import cv2 in my file.
I tried to rename the cv2.cpython-37m-x86_64-linux-gnu.so to cv2.so and then copy to the folder "/home/user/anaconda/lib/python3.7/site/package", but I still cannot see the opencv library in the PyCharm's project interpreter using the anaconda python interpreter and also cannot use the opencv library.
Because I built the OpenCV 4.0 by Cmake, I didn't install the anaconda's opencv library using conda command.
In PyCharm, I added the "/home/user/anaconda/lib/python3.7/site/package" to the "Add content root" in the "file–>setting–>project:server–>project structure", but it didn't fix my problem.
Please help. Thanks.
