I have already used tesseract 4.0 version for training on hand written digits. The steps are as follows: 1.The best way to do is use some handwriten fonts from Google or any where else. 2.use the "tesstrain.sh" script to generate the starter trained data using the text corpus containing only 0-9 digits in a random function , create such a text corpus and generate the starter trained . 3. Use the starter trained data to generate final traineed data after lstm training
If you want a detailed description, I can supply you with a complete documentation of steps.
