昨天导入face_recognition没问题，但是突然间它不起作用.我不知道如何解决此问题...任何帮助将不胜感激.

There was no problem importing face_recognition yesterday but all of sudden it does not work. I have no idea how to fix this problem... Any assistance would be highly appreciated.

我重新启动了Mac，现在再次尝试可以正常工作.我想弄清楚为什么...

I restarted my mac and tried again now it works fine. I would like to figure out why...

>>> import dlib
>>> import face_recognition 
>>>

推荐答案

请通过 import sys 导入sys.

然后替换

np.set_printoptions(threshold = np.nan)

使用

np.set_printoptions(threshold = sys.maxsize)
