AttributeError: 'cv2.CascadeClassifier' object has no attribute 'detectMultiScaleWithScores'

After installing, I ran test_pipeline.py and failed.

I don't think it has such method ever, but it looks like detectMultiScale (without WithScores)? I changed it accordingly in my local and seems to be working.

In cascade_detector.py, in the detectWithAngles function, go to around line 100. You will see the function call to self.detectMultiScaleWithScores. Immediately below that, find:

for face in faces:
    xp = face[0][0]
    dx = face[0][2]
    yp = face[0][1]
    dy = face[0][3]
    score = face[1]

and replace it with:

for face in faces:
    xp = face[0]
    dx = face[2]
    yp = face[1]
    dy = face[3]
    score = 1

This fixes the problem because the self._cascade_classifier.detectMultiScale call on line 60 does not return scores. After making this change, test_pipeline.py seems to be working and generates outputs (that look correct?).

Hi there,
I faced similar error, and solved things as mentioned. But, it does not seem that the faces are aligned anymore. Specifically, see the Fayssal_Mekdad_0002_face_0.aligned imaged under the aligned folder.

Any update on this? Though, I doubt that this might be causing problem.

Any help will be highly appreciated.

I have the same problem

@umitanuki @mayankgrd
Have you solved this problem?

[sirnicolaz]

I have found the solution: the code is using an outdated version of the method. Just go to line 60 of cascade_detector.py and turn detectMultiScaleWithScores into detectMultiScale
