mprof python memory profiler

instalei memory_profiler no meu sistema e executei este programa

!/usr/bin/env python
from memory_profiler import profile

@profile(precision=4)
def my_func():
    a = [1] * (10 ** 6)
    b = [2] * (2 * 10 ** 7)
   del b
   return a

if __name__ == '__main__':
   my_func()

Depois de executar o python fp.py ele mostrou

Filename: fp.py

     9  20.5273 MiB   0.0000 MiB       return a

mas durante a execução do mprof fp.py devolve
