문제

I am new to pytorch and started with this github code. I do not understand the comment in line 60-61 in the code "because weights have requires_grad=True, but we don't need to track this in autograd". I understood that we mention requires_grad=True to the variables which we need to calculate the gradients for using autograd but what does it mean to be "tracked by autograd" ?
