   Is there a specific reason memory_usage return None when stream=True ?

   @PveOnly Looking at the method you describe, I think stream is not intended to receive a boolean, but instead a file or a file-like object.

   stream : File
   if stream is a File opened with write access, then results are written
   to this file instead of stored in memory and returned at the end of
   the subprocess. Useful for long-running processes.
   Implies timestamps=True.

   So if you supply something as the stream parameter, it will try to write output there, instead of returning it.

   In your example that could be something like:

   with open('outputfile', 'w') as filehandle:
       mem_usage, res = memory_usage((func,args,kwargs), stream=filehandle, retval=True)
