Previous version: a.grad, b.grad, c.grad, d.grad = None, None, None, None instead it's appropriate to just set 0. instead of "None" as follows: a.grad, b.grad, c.grad, d.grad = 0. , 0. , 0. , 0.

Fixes #ISSUE_NUMBER : PyTorch Docathon H1 2025 #153952
file location: https://github.com/pytorch/tutorials/blob/main/beginner_source/examples_autograd/polynomial_autograd.py
Description
Previous version:
a.grad, b.grad, c.grad, d.grad = None, None, None, None
Proposed version:
Deletion on that code snippet or at least put a comment on that code snippet. It eventually runs successfully with verified numerical outputs.
