memory_profiler does not print anything

Guys - I know it is fixed for python3 but I am still getting this error. I reinstalled the profiler but the error is persistent.

MBP:python$ sudo -H pip3 install -U memory_profiler

And here is the code I am trying to profile:

from memory_profiler import profile

@profile
class Foobar(object):
    def __init__(self, x):
        self.x = x

if __name__ == '__main__':
    f = [Foobar(i) for i in range(1000000)]

Try this.

from memory_profiler import profile
class Foobar(object):
    @profile
    def __init__(self, x):
        self.x = x
