How to solve this captcha

Not an issue, but am not getting the trainer to solve this.

I Tried all the examples provided in the projects folder but non worked.
Could you help please?

You'll need more samples to train a model, but initially it looks like you might be able to invert the image and then binarize it using a high enough threshold to make the numbers black and the background white. If more samples reveal that there's little to no distortion and that there's always just 4 characters, then that'll help as well.
