Merge pull request #2685 from stweil/lstm.train 
Don't create OCR result files when training data is created
 2019-10-02 22:00:41 +03:00

1e84a6f225 Don't create OCR result files when training data is created 
The configuration file lstm.train causes Tesseract to generate
training data for training of an LSTM line recognizer.

In this mode, no other files with OCR results should be written.
Without this patch, Tesseract writes a small text file.

5b976bfb55 fix langdata (user words/patterns) file suffixes for LSTMs: 
- add another constructor for LSTMRecognizer
  which takes the language_data_path_prefix configured/selected
  at runtime and passes it to the internal CCUtil
- use this in Tesseract::init_tesseract_lang_data when LSTMs
  are available
