MMM-Facial-Recognition-Tools error

[acabrera2012]

Hello everyone,

I have been trying for weeks to get the facial recognition to work with my magic mirror. I have searched this forum and google but I can’t quite seem to find an answer to my problem. Here is the error I get when I’m trying to test it:

OpenCV Error: Bad argument (This LBPH model is not computed yet. Did you call the train method?) in predict, file /home/pi/opencv_contrib-3.3.0/modules/face/src/lbph_faces.cpp, line 396
Traceback (most recent call last):

cv2.error: /home/pi/opencv_contrib-3.3.0/modules/face/src/lbph_faces.cpp:396: error: (-5) This LBPH model is not computed yet. Did you call the train method? in function predict

I have trained the LBPH model multiple times using .jpg’s as well as using the camera on my own face. This is what I’m running:

• Raspberry PI 3
• Raspberry pi cam
• OpenCV-3.3.0
• Python 2.7 (I also have Python 3 installed)
• Electron 1.7.9
• Node 8.9.1
• npm 5.6.0

If anyone has any idea how I can better troubleshoot this error through logs or any other means, please let me know. I’m so close to being up and running but I can’t seem to make any real progress on this one. Thanks.

@acabrera2012 SOLVED!

I changed “model.save(config.TRAINING_FILE)” to “model.write(config.TRAINING_FILE)” in train.py
