树莓派5安装opencv

1 建立虚拟环境

参考网站

https://www.piwheels.org/faq.html#venv

虚拟环境建立过程：

To create a virtual environment:

$ sudo apt install virtualenv python3-virtualenv -y
$ virtualenv -p /usr/bin/python3 testpip

sudo apt install virtualenv python3-virtualenv -y
virtualenv -p /usr/bin/python3 testpip

Enable it:

$ source testpip/bin/activate

source testpip/bin/activate

Now you can use pip or pip3 to install packages into your environment:

(testpip) $ pip3 install numpy
