Unable to import cv2 module (Python 3.6)

问题

total nexwbie here.

I'm unsuccessfully trying to install the cv2 module for python but it doesn't work. I'm working with Python 3.6 (64bits)

I typed the following commands in the cmd :

C:\Users\leahj>C:\Users\leahj\AppData\Local\Programs\Python\Python36\Scripts\pip3 install cv2
Collecting cv2
  Could not find a version that satisfies the requirement cv2 (from versions: )
No matching distribution found for cv2

C:\Users\leahj>C:\Users\leahj\AppData\Local\Programs\Python\Python36\Scripts\pip3 install opencv
Collecting opencv
  Could not find a version that satisfies the requirement opencv (from versions: )
No matching distribution found for opencv

C:\Users\leahj>C:\Users\leahj\AppData\Local\Programs\Python\Python36\Scripts\pip3 install opencv2
Collecting opencv2
  Could not find a version that satisfies the requirement opencv2 (from versions: )
No matching distribution found for opencv2

I tried to look for answers on this site but couldn't find any. The most accurate thing I found was that : https://breakthrough.github.io/Installing-OpenCV/ but it seems that I have to go back to an older version of Python ?

回答1:

Try to do:

pip3 install opencv-python

回答2:

It works for python 3.5

For python 3.6 The conda install opencv and conda install -c conda-forge opencv methods for OpenCV continue to be BROKEN for video/image reading and display.

Use pip install below instead:

python -m pip install opencv-python
