tesseract unpack is a new feature by @stweil - not yet in the master branch. I was testing to see that your lstmf files are read correctly and they are.
For tesstrain, all you need are single line images and their gt.txt. I ram lstmtraining using your lstmf files, which worked fine. If you want to test, try the following in a directory where you have the two sample lstmf files. Change ~/tessdata_best to wherever you have the best traineddata file. ls -1 *.lstmf > all-lstmf mkdir -p ./testdir combine_tessdata -e ~/tessdata_best/eng.traineddata ./testdir/eng.lstm time lstmtraining \ --debug_interval -1 \ --model_output ./testdir/impact \ --continue_from ./testdir/eng.lstm \ --train_listfile all-lstmf \ --traineddata ~/tessdata_best/eng.traineddata \ --max_iterations 400 On Thu, Jan 16, 2020 at 3:59 PM 'Fabio Lugli' via tesseract-ocr < tesseract-ocr@googlegroups.com> wrote: > The command *tesseract unpack* is not recognized by my version of > tesseract, is it a utility that you have yourself or is it already there in > any release? > Anyway does it only extract the *.box *.*gt.txt .tif* files?
