this is the error i m getting.Can you tell me what to do in that

I am having this error on printing faces_detected after using faceDetection module -

OpenCV(3.4.2) c:\miniconda3\conda-bld\opencv-suite_1534379934306\work\modules\imgproc\src\color.hpp:253: error: (-215:Assertion failed) VScn::contains(scn) && VDcn::contains(dcn) && VDepth::contains(depth) in function 'cv::CvtHelper<struct cv::Set<3,4,-1>,struct cv::Set<1,-1,-1>,struct cv::Set<0,2,5>,2>::CvtHelper'

in the line -
gray_img = cv2.cvtColor(test_img,cv2.COLOR_BGR2GRAY)

Can you define Haar cascades?

cv2.error: OpenCV(4.1.1) /home/pi/opencv_contrib/modules/face/src/lbph_faces.cpp:365: error: (-210:Unsupported format or combination of formats) Labels must be given as integer (CV_32SC1). Expected 4, but was 6. in function 'train'.
Can you please help me ?

faces_detected,gray_img=fr.faceDetection(test_img)

faces_detected.gray_img=fr.faceDetection(test_img)

Which version of opencv should I install ???

how to train images present in DataBase?

Instead of training photos from a folder, how can we train images present in data base..?

Traceback (most recent call last):

I don't know what to do in this phase!

How to train like, giving ID of person and getting dataset and training them.
Can we store, trained data of different people in same .yml file ?

module 'cv2.cv2' has no attribute 'face'

in line---> "face_recognizer=cv2.face.LBPHFaceRecognizer_create()"

This is not an issue but curious to know why do we have resizedimages folder. Code worked fine without that folder too.
But if I have to use this code on my own dataset, can I resize it first and run the trainer to save time ? Will the accuracy be same ?
