Failed to continue from: /home/robert/tesstutorial/trainplusminus/eng.lstm

Hello,

I'm trying to train the traineddata with the new tutorial for the finetune training: https://github.com/tesseract-ocr/tesseract/wiki/TrainingTesseract-4.00#fine-tuning-for-%C2%B1-a-few-characters

I execute the commands as the tutorial showing.  Executing the commands as following:

1. training/tesstrain.sh --fonts_dir /usr/share/fonts --lang eng --linedata_only \
  --noextract_font_properties --langdata_dir ../langdata \
  --tessdata_dir ./tessdata --output_dir ~/tesstutorial/trainplusminus
2. training/tesstrain.sh --fonts_dir /usr/share/fonts --lang eng --linedata_only \
  --noextract_font_properties --langdata_dir ../langdata \
  --tessdata_dir ./tessdata \
  --fontlist "Impact Condensed" --output_dir ~/tesstutorial/evalplusminus
3. training/combine_tessdata -e tessdata/best/eng.traineddata \
  ~/tesstutorial/trainplusminus/eng.lstm
4. training/lstmtraining --model_output ~/tesstutorial/trainplusminus/plusminus \
  --continue_from ~/tesstutorial/trainplusminus/eng.lstm \
  --traineddata ~/tesstutorial/trainplusminus/eng/eng.traineddata \
  --old_traineddata tessdata/best/eng.traineddata \
  --train_listfile ~/tesstutorial/trainplusminus/eng.training_files.txt \
  --max_iterations 3600


When I excute the 4th command, there is an error appears:
Failed to continue from: /home/robert/tesstutorial/trainplusminus/eng.lstm

I check the 'eng.lstm' file in the dir of /home/robert/tesstutorial/trainplusminus,  and it exists.

But why Tess4 cannot continue from the file?

And when I execute the 1st command. An error: Failed to read data from: ../langdata/eng/eng.config

In case you are still stuck here, I fixed this issue by downloading the latest version of eng.traineddata
