NameError：名称“FaceDetector”未定义

Question

我试图运行这段代码，但它说

NameError                                 Traceback (most recent call last)
<ipython-input-5-49e303967177> in <module>
      3 
      4 #Detector object created
----> 5 fd=FaceDetector(frontal_cascade_path)

NameError: name 'FaceDetector' is not defined

这是代码：-

#Frontal face of haar cascade loaded
frontal_cascade_path="../input/haarcascade-frontal-faces/haarcascade_frontalface_default.xml"

#Detector object created
fd=FaceDetector(frontal_cascade_path)

阅读this。您需要将FaceDetector 导入到您的代码中：

from face_detector import FaceDetector
