title: Is there any working memory profiler for Python3
body: <p>In Python 2 there's a couple of tools but everything seems to be old and out-of-dated. </p>
  
  <p>I've found PySizer and Heapy but everything seems to be Python2 oriented and would take a lot of effort to port.</p>
  
  <p>objgraph is interesting but still not a fully working profiler</p>
  
  <p>Which tool are using ?</p>
