opencv - 无法在Arch Linux上运行opencv_createsamples

Question

我在arch Linux上安装了opencv和opencv-samples。但是，当我尝试运行opencv_createsamples时，出现了opencv_createsamples: command not found错误，我尝试通过pacman和pip安装opencv。结果是一样的。有人知道如何解决此问题吗？
感谢您的帮助

These apps has been disabled during legacy C API removal. Rewriting them with C++ API was not an option because it is too easy to break them and hard to test.

[...]

Consider using these apps for training from 3.4 branch for Cascade Classifier. Model format is the same between 3.4 and 4.x.

较新的opencv版本不再包含级联训练二进制文件(因为opencv试图摆脱旧的C代码)。尝试使用较旧的opencv版本。经过较旧的opencv版本二进制文件训练的级联分类器应该仍可与最新的opencv库一起用于对象检测。
