在Python 3.6上安装OpenCV：ModuleNotFoundError

Question

I am getting the following error when using import cv2 :

ModuleNotFoundError: No module named 'cv2'

My version of Python is 3.6 64 bit. I have downloaded the whl file to install it via pip manually, and have also installed it with pip install opencv-python however I still get ModuleNotFoundError .

pip outputs Requirement already satisfied: opencv-python in c:\\...\\python36\\site-packages

Help would be much appreciated.

Answer 1

Your download must have been corrupted. It happened to me too. Simply uninstall the package and use

sudo apt-get install python open-cv

Answer 2

使用pip install -U opencv-python
