different from the file now.

Look at the error messages.
Search for 'Failed'

You now have more langdata related errors.

Re: [tesseract-ocr] Error in training Tesseract 4.0. Training gets completed somehow but then the output it gives after reading the pdf is incorrect.

2018-02-15 Thread ShreeDevi Kumar

You are missing langdata files

Failed to load script unicharset from:/home/adarsh/tesseract/
langdata/Latin.unicharset

Failed to read data from: /home/adarsh/tesseract/langdata/radical-stroke.txt
Error reading radical code table /home/adarsh/tesseract/
langdata/radical-stroke.txt

Even after you fix the above, this is only first step of LSTM training
process.

It creates a starter traineddata and lstmf files to be used by
lstmtraining.

The starter traineddata cannot be used to OCR.

Please read wiki pages regarding training 4.0
