**How severe does this issue affect your experience of using Ray?**

- High: It blocks me to complete my task.

Hi! I am trying to modify the @ray.remote api to add some options, but I can’t figure out how to do it. Specifically, I think I should modify def rmote() in `python/ray/_private/worker.py`, and it called functools.partial(). When I go to the definetion of this function, it jumps to a file which is not in ray’s repository. Why this happen? Is it because it generate this file during compiling?

Ok, this is a stupid question, functools.partial() is part of python standard library
