我如何在 python 3.8 上导入 cv2

Question

I am tryin to do a project that requires cv2 module. I downloaded the library through windows command prompt. pip install cv2module it installed successfully. but, when i try to import it on pycharm or python IDLE it throws an error like ImportError: DLL load failed while importing cv2: The specified module could not be found.

Answer 1

安装 contrib 版本 opencv

pip install opencv-contrib-python

Answer 2

I was facing missing DLL issue.

1. I deleted cv2 and openCV folder from the Python\\Python38\\Lib\\site-packages\\ folder in my system. 2.Installed Media feature pack on windows 10 from Optional features settings. 3.Then ran pip install opencv-python again.
2. Rebooted my system and import cv2 worked like a charm.
