## README

# opencv-python-learn
学习Opencv-Python
## Environment
- OS: Linux Deepin 20 amd 64
- Python: 2.7.16 + 3.7.3( Use this)
- opencv-python: 4.4.0.46
## Install opencv-python
### 最小化安装
只安装核心模块
```bash
pip3 install opencv-python  # 安装
pip3 uninstall opencv-python    # 卸载
```
### 完全安装
包含核心模块和额外的模块
```bash
pip3 install opencv-contrib-python  # 安装
pip3 uninstall opencv-contrib-python # 卸载
```
### apt安装
由于我使用的是Deepin OS，pip3设置了清华镜像也无法pip3下载。。于是我用apt搜索了下，真的有，不过版本还是3.2时代的，现在都4.4了，勉强吧。
```bash
$ sudo apt install python3-opencv  # 安装
$ sudo apt remove python3-opencv  # 卸载
```
## Question
1. 为啥引入cv2前都要引入numpy？[Bug吐槽](https://zhuanlan.zhihu.com/p/99597714)
