Hi! Great library, thanks for sharing it!

I'm dealing with this captcha:

Do you think that is possible to train a model based on this captcha?

Thanks a lot !

Some of the digits are difficult even for a human, but there are a couple of flaws in the system that you can use to your advantage.

Always exactly 6 digits
Only 10 different characters (use character_set: "0123456789")
No horizontal translation (maybe try fixed_blob_locations like this or maybe exact_characters: 6, exact_characters_width: 7 like this)
