Not able to read model file!

In line 70
fisher_face_emotion = cv2.face.FisherFaceRecognizer_create() fisher_face_emotion.read('E:/GitHub/facifier/src/models/emotion_classifier_model_windows.xml')

I am getting an error as follows:
e:/GitHub/facifier/src/facifier.py Traceback (most recent call last): File "e:/GitHub/facifier/src/facifier.py", line 70, in <module> fisher_face_emotion.read('E:/GitHub/facifier/src/models/emotion_classifier_model_windows.xml') cv2.error: OpenCV(4.4.0) C:\Users\appveyor\AppData\Local\Temp\1\pip-req-build-6lylwdcz\opencv\modules\core\src\persistence.cpp:2089: error: (-215:Assertion failed) isMap() in fu\src\persistence.cpp:2089: error: (-215:Assertion failed) isMap() in function 'cv::FileNode::operator []'

How to fix this?

Specifications

1. Python 3.7.6 conda
2. OpenCV(4.4.0)

I searched this error and found the same issue reported in opencv (opencv/opencv#14908)
Their solution is to retrain the model and it could load.

I'm guessing it's caused by newer version of OpenCV that removes the isMap() function.
Try downgrading to older versions of OpenCV such as 3.4.4 or 2.4.13.6

I tried with OpenCV 3.4.4, it still gave the same error, will retrain and get back with new update

It worked!
