Hi Shree, Thank you for the suggestion. I have checked for the fonts available in my system. 'dejavu' is available. So, i thought of first checking for this font. So i ran the following command:
src/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 --fontlist 'dejavu' But it still throwing the error: ''' Could not find font named dejavu. Pango suggested font FreeMono. Please correct --font arg. + [[ 0 -gt 0 ]] + check_file_readable /tmp/tmp.ZyN6KA8ZSJ/eng/eng.dejavu.exp0.box /tmp/tmp.ZyN6KA8ZSJ/eng/eng.dejavu.exp0.tif + for file in '$@' + [[ ! -r /tmp/tmp.ZyN6KA8ZSJ/eng/eng.dejavu.exp0.box ]] + err_exit '/tmp/tmp.ZyN6KA8ZSJ/eng/eng.dejavu.exp0.box does not exist or is not readable' + echo -e 'ERROR: /tmp/tmp.ZyN6KA8ZSJ/eng/eng.dejavu.exp0.box' does not exist or is not readable + tee -a /tmp/tmp.ZyN6KA8ZSJ/eng/tesstrain.log ERROR: /tmp/tmp.ZyN6KA8ZSJ/eng/eng.dejavu.exp0.box does not exist or is not readable + exit 1 '''' Can you please give some suggestions on this...
