Could someone tell me why is it requiring a output file or something, thank you.

Try creating a directory called output. Looks like it is trying to save an output sample, but it can't find the directory to save it in.

Thank you so much for replying me after such a short minutes. I soon found it in README.md after asking the question, should have read it carefully first.
