autopep8 does not fix any indentation

I have a file test.py with the following code

class MyClass():
y = 2
def my_func(self):
x = 2
return(x)

When I run pycodestyle test.py I get

test.py:2:1: E112 expected an indented block
test.py:2:1: E305 expected 2 blank lines after class or function definition, found 0
test.py:3:1: E302 expected 2 blank lines, found 0
test.py:4:1: E112 expected an indented block
test.py:4:1: E305 expected 2 blank lines after class or function definition, found 0

However running autopep8 test.py does not fix any indentation. It returns

class MyClass():


y = 2


def my_func(self):


x = 2
return(x)

I expect it to return

class MyClass():

    y = 2

    def my_func(self):
        x = 2
        return(x)

Am I expecting too much of autopep8?
