some examples of pytorch syntax (contd now consider the following exampleclass encoderrnn(torch nn module)def __init__(selfinput_sizehidden_size)super(encoderrnnself__init__(==the rest of the definition ==we are obviously trying to define new class named encoderrnn as subclass of torch nn module and the method init (is there to initialize an instance object constructed from this class but why are we making the call super(encoderrnnselfinit (and supplying the name of the subclass again to this methodto understand this syntaxyou have to know how you can ask method to get part of the work done by method defined for one of its superclasses how that works is different for single-inheritance class hierarchy and for multiple-inheritance class hierarchy purdue university
