No module called cv2

Question

I am using Ubuntu 18.04 and I follow the official install instruction of OpenCV. When I tried to import cv2 on python3.8, it shows

No module named cv2 

but for python2.7, it works for me and I use the command cmake../ to access and it only shows python2.7 has built into it. Does anyone meet the same problem? Please see the screenshot for more details.

Answer 1

Have you tried installed python package opencv-python using pip?

Try this

pip3 install opencv-python

Answer 2

Open the containing folder of your python.exe of Python 2.7, and there you will find the site-packages folder. In there, copy the cv2 folder, and paste it into the Python 3.8 site-packages folder.
