Issues with tesstrain.sh

[sibi kanagaraj]

Dear all ,

I am trying to run a mass training with tesstrain.h (Have applied patch too ) . Still I am not able to clear my hurdles .
This is the command which I used

./tesstrain.sh \
        --bin_dir /usr/local/bin/ \
        --fonts_dir /usr/share/fonts/ \
        --lang tam \
        --langdata_dir /home/tesseract/training/langdata \
        --output_dir /home/tesseract/tam_train/output/ \
        --training_text /home/sibi/Desktop/outputscrambled.txt \
        --wordlist /home/sibi/Desktop/word_list_lexicon.txt \
        --tessdata_dir /usr/local/share/tessdata \
        --fontlist "TAU_VASN"

and I got the following output

tee: /tam/tesstrain.log: No such file or directory

ERROR: Program text2image failed. Abort.


What exactly does //Could not find font named TAU_VASN// mean ? I read the tesstrain.sh introduction again , which quotes
"# NOTE: The font names specified in --fontlist need to be recognizable by Pango using  fontconfig. An easy way to list the canonical names of all fonts available on
 your system is to run text2image with --list_available_fonts and the  appropriate --fonts_dir path."

And hence I performed the following command

 text2image --list_available_fonts --fonts_dir usr/share/fonts
For which I got the output as

Initializing fontconfig

I am not able to get any interpretable data from this . Though the font is present in usr/share/fonts why is it not recognising it .

Once I am able to clear this , I will start looking at what mistakes I made in the other parameters and start correcting them . If community members are able to point out mistakes in the paramters it would be great .
