My module memory_profiler is capable of printing a line-by-line report of memory usage and works on Unix and Windows (needs psutil on this last one). Output is not very detailed but the goal is to give you an overview of where the code is consuming more memory, not an exhaustive analysis on allocated objects.
After decorating your function with @profile and running your code with the -m memory_profiler flag it will print a line-by-line report like this:
Line # Mem usage Increment Line Contents
