Before adding _1 to all of my training captchas I've got this error:

I had the same issue. Check config.py file and make sure that IMAGE_HEIGHT, IMAGE_WIDTH and CHAR_SETS fits your Dataset needs. Otherwise, It will crash trying to read your dataset images under an unexpected resolution.

@EzequielAdrianM And how are your filenames like?
Image width and height are correct, CHARS_NUM = 6, but the script just doesn't want to process 2BFG6C_1.jpg!

@moermann Hi,I had the same issue. Maybe you can check CHAR_SETS in config.py and you'll find there is a O lost ,just add O here and try again.
