树莓派3B+安装opencv坑点,遇到了ImportError: libhdf5_serial.so.100: cannot open shared object file: No such file

ImportError: libhdf5_serial.so.100: cannot open shared object file: No such file or directory
原因：缺少了若干模块
解决方案：直接安装

底下命令建议一行一行输入：搞了我好几天累死

pip3 install opencv-contrib-python==3.3.0.9 -i https://www.piwheels.org/simple # 安装3309版本
sudo apt-get update #安装依赖库
sudo apt-get install libhdf5-dev
sudo apt-get install libatlas-base-dev
sudo apt-get install libjasper-dev
sudo apt-get install libqt4-test
sudo apt-get install libqtgui4
sudo apt-get update

python3
import cv2 # 检查导入成功
