What PyTorch Really Means by a Leaf Tensor and Its Grad

The article delves into the fundamental mechanics of PyTorch's autograd system, emphasizing the significance of leaf tensors and the 'requires_grad' flag in gradient computation. It clarifies that leaf tensors are the original tensors with 'requires_grad=True', serving as the starting points for gradient calculations during backpropagation, and highlights how understanding this distinction enhances debugging and model optimization.
