Hello

I use the version OCV3 of face recognition.
My problem is when I try again my face to increase the hit rate, I get the error message when typing “python tools.train.py”:

Remember to set the name list environment variable FACE_USERS
Reading training images…

Assign label 1 to Alfred

OpenCV Error: Assertion failed (ssize.width > 0 && ssize.height > 0) in resize, file /home/pi/opencv/modules/imgproc/src/imgwarp.cpp, line 3483
