[tesseract-ocr] How can I do the training using my own image in Tesseract 4.0

[cheng . bo]

I have a bunch of images, containing English words.
I would like to generate training data by these images, and do the training.
How should I do?

Thanks a lot.

[tesseract-ocr] LSTM training error after some iterations

[cheng . bo]

I tried to train the English from scratch by following the tutorials in:
https://github.com/tesseract-ocr/tesseract/wiki/TrainingTesseract-4.00
However, the training will fail after some iterations with the message as 
follows:

lt-lstmtraining: ../ccutil/genericvector.h:696: T& 
GenericVector::operator[](int) const [with T = char]: Assertion `index 
>= 0 && index < size_used_' failed.

What is going on?
How can I fix this?
Many thanks.
