Why Does Dataset class Inheritance not require the Super Constructor

1

In the pytorch tutorial for the dataloader:
https://pytorch.org/tutorials/beginner/data_loading_tutorial.html

When the Dataset class is inherited by the FaceLandmarksDataset class below.
Super is not used to initialize the Dataset class.
Why is this?
I dont understand how inheritance of the Dataset class works if the Dataset class is not initialized with the Super constructor.

class parent:
    def plus_one(self, x):
        return x+1

class child(parent):
    pass

instance = child()
instance.plus_one(1)

As you can see, the child class dose not have any method. It just inherits its parent class.
