Unable to install cv2 on windows

Question

I am trying to install opencv in python on my windows machine but I am unable to do so. I have python 2.7.11::Anaconda 2.4.1 <32-bit>

Here is what I have tried till now -

1. pip install cv2 on command line gives the error :

could not find a version that satisfies the requirement cv2

2. I downloaded the package from sourceforge site, followed the steps and pasted cv2.pyd in C:\Python27\Lib\site-packages but still it is not working. I get the following error message

ImportError: No module named cv2

(I already have numpy installed and it works just fine).

Answer 1

pip install opencv-python

you can type this instead of

pip install cv2 

it also works with anaconda pro

Answer 2

I was able to solve the error.

If you are using python version 3 , sometimes you have to use pip3.

pip3 install opencv-python

Make sure you are using python 3 , it won't work for python 2.

Answer 3

尝试

pip install opencv-python==4.3.0.36

Answer 4

所以我使用的是 PyCharm，对我有用的是直接从文件->设置、项目：您的项目名称->Python 解释器列表安装它
