[ADBYITS]

Hi guys I just got all the code and thought i got all the way though the FR stuff but i keep getting a error when i run faces.py

PS C:\Users\ADBY\Desktop\Coding\OpenCV-Python-Series-master\src> python .\faces.py OpenCV Error: Unspecified error (File can't be opened for reading!) in cv::face::FaceRecognizer::read, file C:\projects\opencv-python\opencv_contrib\modules\face\src\facerec.cpp, line 61 Traceback (most recent call last): File ".\faces.py", line 11, in recognizer.read("trainner.yml") cv2.error: C:\projects\opencv-python\opencv_contrib\modules\face\src\facerec.cpp:61: error: (-2) File can't be opened for reading! in function cv::face::FaceRecognizer::read

check that traiiner.yml exists. It was moved to the folder "recognizers" and renamed face-trainner.yml in the repo

you need to make sure in the images folder that there's a subdirectory. That subdirectory should have images of you in it. Run face-trainer.py and then run faces.py. It will find the directory and then the label will be put onto the image.

[ADBYITS]

Yep done a that and ran the output and can see it seeing my folder and same deal

Trainer was moved and code has been updated.

[SparshMaheshwari]

Should the trainer.yml be empty ? If not then what must be there in it ?

[hirenkhatri]

In OpenCV 3.3

load() is replaced by read()

save() is replaced by write()

Just copy the folder given below in your main folder of Face-Recognition-Based-Attendance-System-master

TrainingImageLabel.zip

[vanetoj]

patel when i use the face_recognizer.train(faces_pca, ids) it tells me "Expected 4, but was 2. in function 'train'" any ideas? thanks
