安装使用Python3的OpenCV的Python在Ubuntu 15.04

Question

我想通过命令在Ubuntu 15.04机器安装OpenCV的Python

pip3 install opencv-python 

但只要我运行此命令，我得到以下错误：

Downloading/unpacking opencv-python 
Could not find any downloads that satisfy the requirement opencv-python 
Cleaning up... 
No distributions at all found for opencv-python 
Storing debug log for failure in /home/Nadeem/.pip/pip.log 

任何帮助将不胜感激。 谢谢！

Answer 1

您可以从源代码安装opencv。
按照this链接来做。
或者您可能需要使用下面的命令

pip3 install --upgrade pip 

Answer 2

在第一次升级来升级您的PIP 3个点使用sudo。

arsho:~/workspace $ sudo pip3 install --upgrade pip                      
Successfully installed pip 

现在再次使用sudo命令安装opencv-python。

arsho:~/workspace $ sudo pip3 install opencv-python 
Successfully installed numpy-1.13.1 opencv-python-3.3.0.10 

最后使用pip检查opencv-python版本和位置信息。

arsho:~/workspace $ pip3 show opencv-python 
--- 
Name: opencv-python 
Version: 3.3.0.10 
Location: /usr/local/lib/python3.4/dist-packages 
Requires: numpy 

我在https://c9.io/使用Ubuntu 14.04.5 LTS测试这一点。
