Tesseract training - text2image returning Segmentation Fault every time on Ubuntu

Question

I'm trying to train a new language by following the oficial turorial but I just cannot perform the steps on "Generate Training Images and Box Files/Prepare a text file". I've created my text file but every single time I run the command text2image --text=training_text.txt --outputbase=eng.TimesNewRomanBold.exp0 --font='Times New Roman Bold' --fonts_dir=/usr/share/fonts the result is Could not find font named Times New Roman Bold. Pango suggested font FreeSerif Bold Please correct --font arg.:Error:Assert failed:in file text2image.cpp, line 437 Segmentation fault (core dumped) .

This happens in the given example (I've used the one they used in the turorial) and on every single font I choose that exists in the list shown by running text2image --text=training_text.txt --outputbase=eng --fonts_dir=/usr/share/fonts --find_fonts --min_coverage=1.0 --render_per_font=false .

Can someone help me with this? I cannot go further with the tutorial because of this...

Thanks!

Answer 1

After a few hours searching about this problem, I found out that what happens is that the font used in the command is not recognized by the OS and the cpp program doesn't validate this situation, therefore a Segmentation Fault occurs.

After using a valid font, all runs smoothly.
