Error:Assert failed:in file ../lstm/lstmtrainer.h, line 110

[roberty...@gmail.com]

Hello,

I use the 'git pull' command to update the code from the link https://github.com/tesseract-ocr/tesseract.git, and I recompile, reinstall the Tess4.0.

But when I execute the command (showed in below) to finetune the traineddata, an error appears: "mgr_.Init(traineddata_path.c_str()):Error:Assert failed:in file ../lstm/lstmtrainer.h, line 110"

lstmtraining --model_output ~/tesstutorial/chituned_from_chisim/chituned \
--continue_from ~/tesstutorial/chituned_from_chisim/chi_sim.lstm \
--train_listfile ~/tesstutorial/chitest/chi_sim.training_files.txt \
--eval_listfile ~/tesstutorial/chitest/chi_sim.training_files.txt \
--target_error_rate 0.01



There is nothing wrong with the Tess before updating the code. But now, An assertion error crashes. Why? Can you help me?

[roberty...@gmail.com]

The code seems to have changed a lot, as well as the training commands and corresponding tutorials. The changes can refer to https://github.com/tesseract-ocr/tesseract/wiki/TrainingTesseract-4.00.

hi how can you solve it? i have this error too.

please help me

You also need to provide a traineddata file as input

Please review the updated training instructions in the wiki and change the training commands accordingly.

I have traineddata in this path: /home/zohreh/tesstutorial/engtrian/eng/eng.traineddata.

that with using :

training/tesstrain.sh --fonts_dir /usr/share/fonts --lang eng    --training_text training/langdata/eng/eng.training_text     --linedata_only \

  --noextract_font_properties --langdata_dir training/langdata \

  --tessdata_dir ./tessdata \

  --fontlist "Times New Roman," --output_dir ~/tesstutorial/engtrian

i created it.

And also i used the link that u sent me.

sorry shree but i  tried alot but i couldn't solve that.

 What problems do you encounter? Please give more information about the problems.

I later used the new tutorial (https://github.com/tesseract-ocr/tesseract/wiki/TrainingTesseract-4.00#fine-tuning-for-impact) to train data, and I didn't have any problems. Hope to help you.

Hi thanks for your help

i used your link. but i got this error:

mgr_.Init(traineddata_path.c_str()):Error:Assert failed:in file ../lstm/lstmtrainer.h, line 110

Segmentation fault (core dumped)

I wanna start train persian language.so im trying english first. i creat boxfile and unicharset .then eng.charset_size=110.txt ,eng.Times_New_Roman.exp0.lstmf , eng.traineddata , eng.training_files.txt , eng.unicharset

that all of those have created with this syntax:

training/tesstrain.sh --fonts_dir /usr/share/fonts --lang eng    --training_text training/langdata/eng/eng.training_text     --linedata_only \

  --noextract_font_properties --langdata_dir training/langdata \

  --tessdata_dir ./tessdata \

  --fontlist "Times New Roman," --output_dir ~/tesstutorial/engtrian

and now i have error that i told you

[roberty...@gmail.com]

Hi, I don't encounter this error.

But you may check your traineddata whether in the correct directory, as well as some other paths.

Thanks alot. you're right .

the path shoulde be compelet i used /home/zohreh/Desktop/tesseract-master/z/engtrian/eng/eng.traineddata  insted of z/engtrain/eng/eng.traineddata.

it just can write the path from root

[Ava Nimaee]

sorry i have a qustion:

what is the output of this syntax.because i after that i have alot of  base44.409_2195.checkpoint. but in tutorials i saw eng.lstm

and i have not that. whic syntax create eng.lstm?

I must thank you for your support at this time

[ShreeDevi Kumar]

Please check the updated tutorials in the wiki. There have been many changes.

 Hi shree, Thanks alot for attention.

i corrected all syntax and i can generate some base70.229_1900.checkpoint and have just files hike it.

but in tutorials, there is eng.lstm. how can i create it . actually what is eng.lstm.

and what is lstm-punc-dawg? it is similar eng.punc's file that Mr.Smit put in landgata/eng?

lstm file is the language model. It is saved in traineddata file.

dawgs are a kind of compressed files, created from lists of words, punctuation or numbers.

You can use dawg2wordlist to unpack them.

Please follow the instructions on the training wiki page.

[Ava Nimaee]

Thank alot for your attention.i follow the  instructions on the training wiki page but really it is confusing in somecircumstance.

So i say again thanks

[Ava Nimaee]

Hi shree

I read instructions on the training wiki page but i dont have eng.lstm

non of the syntaxs create eng.lstm. how can i create it. even i check langdata which i download it form git amd there is't there.

i spend alot of time but i don't khonw how i can create it.

can you tell me.

Please see https://github.com/tesseract-ocr/tesseract/wiki/TrainingTesseract-4.00#fine-tuning-for-impact

The following command extracts the .lstm file from the .traineddata file.

training/combine_tessdata -e tessdata/best/eng.traineddata \
  ~/tesstutorial/impact_from_full/eng.lstm
