For LSTM training, box files need to have an additional line for each text line with the tab character to indicate a new line.
If you have existing box/tiff pairs, you can use a box editor (such as
jtessboxeditor) and insert a box at end of each line and add a tab
character in it.
>On the toolbar, the Character textbox has a built-in conversion function.
If you enter U+0009 and hit Enter key or click on the adjacent Tool icon,
the escape sequences will be converted to Unicode. You can also enter the
tab character via Alt+09 numpad keys on Windows.
o
r add a dummy sequence such as @@@ and then replace to tab character in a
text editor.
See attached files as a sample.
Then modify tesstrain.sh to copy the box tiff pairs to the training
directory before starting training
mkdir -p ${TRAINING_DIR}
tlog "\n=== Starting training for language '${LANG_CODE}'"
cp ./*.box "${TRAINING_DIR}/"
cp ./*.tif "${TRAINING_DIR}/"
