你好，我需要一些帮助，我试图在 python 3.7 中安装 opencv，但我在互联网上发现它不受支持，所以你必须从头开始构建它。
我遵循了本教程这里我可以成功地将其构建到 100%，直到出现错误。

我正在运行的操作系统这里
我在 Raspberry pi 3b+ 上运行 Ubuntu Server
ubuntu@ubuntu:~/opencv-4.1.2/build$ uname -a Linux ubuntu
5.3.0-1017-raspi2 #19-Ubuntu SMP Thu Jan 16 18:25:50 UTC 2020 aarch64 aarch64 aarch64 GNU/Linux
这是我遇到的错误：
c++: fatal error: Killed signal terminated program cc1plus
compilation terminated.
make[2]: *** [modules/python2/CMakeFiles/opencv_python2.dir/build.make:63: modules/python2/CMakeFiles/opencv_python2.dir/__/src2/cv2.cpp.o] Error 1

希望得到一些帮助，谢谢。

我做了大量研究并找到了解决方案，因为没有人能够回答我的问题，所以我认为我可以在这里发布解决方案......
我使用这个自动脚本在我的 raspberry pi 中构建和安装 opencv ^_^，你可以下载它这里
如果您在构建过程中遇到困难，您可以随时尝试以下代码：
代码：
sudo dd if=/dev/zero of=/swapfile bs=64M count=16
sudo mkswap /swapfile
sudo swapon /swapfile
After compiling, you may wish to
Code:
sudo swapoff /swapfile
sudo rm /swapfile
