Help: Unable to Combine the Output Files - Training from Scratches

[minh...@gmail.com]

Dear all, 

I follows the manuals in wiki, but still get errors at the end. 

I work in Mac OS 10.15.6 Catalina

Tesseract 4.1.1

Lstmtraining 4.1.1

Here is my process:

# Create train data, language Viet for only Time New Roman FONT

PANGOCAIRO_BACKEND=fc \
~/tesseract/src/training/tesstrain.sh \
--fonts_dir /Library/Fonts \
--lang vie \
--linedata_only \
--noextract_font_properties \
--exposures "0" \
--langdata_dir ~/tesstutorial/langdata \
--tessdata_dir ~/tesstutorial/tesseract/tessdata \
--fontlist "Times New Roman" \
--training_text ~/tesstutorial/langdata/vie/vie.training_text \
--output_dir ~/tesstutorial/vietrain

in dir ~/tesstutorial/langdata: I put the best vie.traineddata, and vie.punc, vie.wordlist, vie.wordlist, vie.number (I don't know if it is necessary?)

# Create evaluation data, language Viet for only Time New Roman FONT

using other data

PANGOCAIRO_BACKEND=fc \
~/tesseract/src/training/tesstrain.sh \
--fonts_dir /Library/Fonts \
--lang vie \
--linedata_only \
--noextract_font_properties \
--exposures "0" \
--langdata_dir ~/tesstutorial/langdata \       (dir has best traineddata Sep 2017)
--tessdata_dir ~/tesstutorial/tesseract/tessdata \  
--fontlist "Times New Roman" \
--training_text ~/tesstutorial/langdata/vie_eval/vie.training_text \
--output_dir ~/tesstutorial/vieeval

# Then I continue training using lstmtraining

lstmtraining \
--debug_interval 100 \
--traineddata ~/tesstutorial/vietrain/vie/vie.traineddata \
--net_spec '[1,36,0,1 Ct3,3,16 Mp3,3 Lfys48 Lfx96 Lrx96 Lfx256 O1c111]' \
--model_output ~/tesstutorial/vieoutput/base \
--learning_rate 20e-4 \
--train_listfile ~/tesstutorial/vietrain/vie.training_files.txt \
--eval_listfile ~/tesstutorial/vieeval/vie.training_files.txt \
--max_iterations 100000 &>~/tesstutorial/vieoutput/basetrain.log

So far, there is no error, there are several base...checkpoint generated

# Last step, combine output

Do I have to provide best traineddata so that the final output traineddata will have all required components?

I get error  Must provide a --traineddata see training wiki 

Here are what I tried

lstmtraining --stop_training \
--continue_from ~/tesstutorial/vieoutput/base_checkpoint \
--traineddata ~/tesstutorial/vietrain/vie/vie.traineddata \        (produced at the first step)
--model_output ~/tesstutorial/vieoutput/vie.traineddata

or 

lstmtraining --stop_training \
--continue_from ~/tesstutorial/vieoutput/base_checkpoint \
--traineddata ~ /tesstutorial/vietrain/vie/vie.traineddata\        (produced at the first step)
--old_traineddata ~/tesstutorial/langdata/vie.traineddata  \    (dir has best traineddata Sep 2017)
--model_output ~/tesstutorial/vieoutput/vie.traineddata

I read carefully wiki, but there is not any solutions.

Please, anyone can point out what wrong with my process?

Is there anything missing?

Many thanks,

TuPM
