What is Tensor?

The fundamental data structure in deep learning frameworks. A 0D tensor is a scalar, 1D is a vector, 2D is a matrix, 3D+ is a tensor. In PyTorch and JAX, tensors track their computation history for automatic differentiation and can live on CPU or GPU. All neural network inputs, outputs, weights, and gradients are tensors.
