text_to_image - как использовать (python3)

Question

Я установил этот пакет в python3. Как это использовать? Я следовал инструкции и получил следующие ошибки:

    print(decode(args.image_path))
  File "decode.py", line 27, in decode
    decoded_text += chr(pixel_value)
TypeError: an integer is required (got type tuple)
