So PyTorch is the new popular framework for deep learners and many new papers release code in PyTorch that one might want to inspect. Here is my understanding of it narrowed down to the most basics to help read PyTorch code. This is based on Justin Johnson’s great tutorial. If you want to learn more or have more than 10 minutes for a PyTorch starter go read that! PyTorch provides automatic differentiation system “autograd” to automate the computation of backward passes in neural networks. We can do forward pass using operation on PyTorch Variables, and uses PyTorch autograd to compute gradients. So, a PyTorch Variable is a wrapper around a PyTorch Tensor, and represents a node in a computational graph.
