问题
I'm using Serak Tesseract Trainer for Tesseract 3.0x. I added a Train Image, which then came from jTessBoxEditor (a Box Generator). When I pressed Train Tesseract, a DOS command prompts me, it's like training the image, then suddenly this appeared:
Reading dos.bookmanoldstyle.exp0.tr ... Font id = -1/0, class id = 1/42 on sample 0 font_id >= 0 && font_id < font_id_map_.SparseSize():Error:Assert failed:in file ....\classify\trainingsampleset.cpp, line 622
then a dialog box appeared that tells something about Shape clustering that has stopped working.
I don't know what went wrong, the first time I used this, it worked fine though. Anyone who can help me resolve this?
回答1:
Save your font_properties file in Unix format (.sh) (which is available in notepad++) instead of normal text. Then use font_properties file as shown below wherever it is needed.
-F font_properties.sh
回答2:
Do you have a correct entry in font_properties file or correct input filename? Assert failed - Training Tesseract
