Hi Gilberto!
Let me know if I can help with anything else.
Which operating system do you use? 32-bit or 64-bit? I suspect that you did not compile Lilypond yourself but used one of the installers. Am I right? If I'm right: Don't use the python interpreter distributed with lilypond, use python 2.7.16.
