title: How to make PyCharm profiler show only timings of my source code, not any libraries?
body: <p>When I run PyCharm profiler (a quick intro video is here -- <a href="https://www.youtube.com/watch?v=QSueV8MYtlw" rel="noreferrer">https://www.youtube.com/watch?v=QSueV8MYtlw</a> ) I get thousands of lines like hasattr or npyio.py (where did it come from, I do not even use numpy) which do not help me to understand what's going on at all.</p>
  
  <p>How can I make make PyCharm profiler to show only timings of my source code, not any libraries or system calls? </p>
  
  <p>In other words, can the time spent in system calls and libraries be assigned to my functions which call them?</p>
  
  <p>In other words (version two), all I want is number of milliseconds next to each line of <em>my</em> python code, not anything else.</p>
