Error by using own model

[Jens Humrich]

Hey everyone,

after training my model and gaining a sufficient accuracy, I copied the checkpoint into the TESSDATA_PREFIX folder and renamed it to jen.traineddata:

cp jens_checkpoint /usr/share/tesseract/4/tessdata/jen.traineddata

When trying to run tesseract with the new language I get the error message:

tesseract --oem 1 -l jen sample.tif stdout

Error opening data file /usr/share/tesseract/4/tessdata/jen.traineddata

Please make sure the TESSDATA_PREFIX enviroment variable is set to your "tessdata" directory.

Failed loading lanugage 'jen'

Tesseract couldn't load any languages!

Could not initialize tesseract.

When simply copying a traineddata file within the folder it works just fine, e.g.

cp /usr/share/tesseract/4/tessdata/eng.traineddata /usr/share/tesseract/4/tessdata/jen.traineddata

Any idea, what I am doing wrong?

Thanks,

Jens

A checkpoint is NOT a traineddata file.

Use -stop-training to build the traineddata.

eg.

echo "#### stop training                                       ####"

~/tesseract/bin/src/training/lstmtraining \

--stop_training \

--continue_from  ./devaplus_z1/plus_checkpoint \

--traineddata ./santrain_z1/san/san.traineddata \

--model_output ./devaplus_z1/devaplus_z1.traineddata
