Next problem with training (tesseract 4.0)

[Adam Funk]

Hi again,

Using the instructions at
<https://www.endpoint.com/blog/2018/07/09/training-tesseract-models-from-scratch>,
I'm getting a bit further, but when my script gets to this part:

combine_lang_model \
--input_unicharset "${UNICHARSET_FILE}" \
--script_dir "${TESSDATA_PREFIX}" \
--output_dir "${OUTPUT_DIR}" \
--pass_through_recoder \
--lang "${LANG_CODE}"

it fails with this error:

Config file is optional, continuing...
Failed to read data from: /home/adam/sandboxes/TEST/tessdata/mem/mem.config
Failed to read data from:
/home/adam/sandboxes/TEST/tessdata/radical-stroke.txt
Error reading radical code table
/home/adam/sandboxes/TEST/tessdata/radical-stroke.txt


I can't figure out from these instructions or the tesseract
documentation on github where the mem.config and radical-stroke.txt
files are supposed to come from. Any help would be greatly appreciated!

Also, the previous tesseract command is creating the *.lstmf files in
the same directory as the *.box and *.tif files --- are they supposed to
be in the TESSDATA_PREFIX directory instead?

Thanks,
Adam

config files are there some languages. They will be in langdata or langdata_lstm repos. radical_stroke.txt is also there.

You can also look at training instructions in wiki or in shreeshrii/tess4training

Those look very useful --- thanks!

Hi again,

I've tried using combine_tessdata -u to unpack the contents of the standard eng.trainedddata to use as a "starter" for all the required files, but the combine_lang_model is still failing with "Failed to read data from: /home/adam/sandboxes/TEST/tessdata/eng/eng.config" error. (I have the setting TESSDATA_PREFIX="/home/adam/sandboxes/TEST/tessdata".)  Where do I get that file?

Thanks,

Adam

English does not have a config file. It is optional. Only used in some languages.

OK, so that "Failed..." is just a warning.  

Thanks!

Failed to read is a generic warning from the common file read routine (as far as I know)

https://github.com/Shreeshrii/tess4training/blob/master/1-makedata.log 

shows
