solution:

cascade_path = "/usr/local/opt/opencv/share/OpenCV/haarcascades/haarcascade_frontalface_default.xml"

to my own xml file path.

[linjianing1997]

yes i did the same

[simimasen]

where to find that xml exactly? It's not in my current folder nor in my opencv folder

[simimasen]

solved it. my opencv installed through my Anaconda, I found this xml file in there.
