I have been trying to train ocr to read digital numbers of scale after doing some process on the pictures such as cropping masking...etc. However, When I train the data I, it keeps giving me this error even though the number of samples for training is more than requried I also tried to increase that but same issue still happening. How may I fix this issue so that I can train the ocr to accuratly read my digits. I have tried to use the build in liberary for the ocr to read the digits but it keeps giving either wrong readings or no readings at all.

Hope it helps!
