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
