安装软件包开始运行一些代码可能是我工作中最难的部分。

Anways，我尝试在anaconda python 3.6环境中安装opencv。我收到错误：

我在Windows系统上。我不明白错误，搜索没有帮助。

欢迎任何有关解决错误的意见或建议。

Answer 1

为了记录，OpenCV与pip安装良好。使用Miniconda和Python 3.6在Windows 10上进行测试：

> pip search opencv
...
opencv-python
...

> pip install opencv-python

告诉我Requirement already satisfied。

要确保已正确安装，请运行：

> python
>>> import cv2
>>>

Answer 2

转到root conda环境。

做conda update conda。

然后只需import cv2并使用它。

使用Conda安装OpenCV
