无法导入 cv2 模块（Python 3.6）

Question

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 ?

Answer 1

试着做：

pip3 install opencv-python

Answer 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
