RPLidar S2 running simple_grabber

[sramesh2002]

Hello, I am trying to run simple grabber and I am getting this following output error:

*** bit out of range 0 - FD_SETSIZE on fd_set ***: terminated
Aborted (core dumped)

What is this error and how do I fix it?
Also, for future reference, is there a way to use python for RPLidar S2?
