python3导入cv2失败

Question

I used python2.7, and have installed opencv, I import cv2 successfully while use python2.7. But when I tried to use python3.4 to import cv2, it said No module named 'cv2',how can I import cv2 with python3

Answer 1

You will need to install openCV for python3 - you can specify which version of python you'd like to use:

for python3:

python3 -m pip install opencv-python

for python2.7:

python2.7 -m pip install opencv-python
