As previously mentioned, PyTorch can compute gradients automatically for us. In order to do that, it tracks computations via a computation graph, and then when it is time to compute the gradient, it moves backward along the computation graph. Actually, computations graphs are also a helpful concept for learning how differentiation (computing partial derivatives and gradients) work, which is what we are doing in this video.
