PyTorch: Tensors ¶. Numpy is a great framework, but it cannot utilize GPUs to accelerate its numerical computations. For modern deep neural networks, GPUs often provide speedups of 50x or greater, so unfortunately numpy won’t be enough for modern deep learning.. Here we introduce the most fundamental PyTorch concept: the Tensor.A PyTorch Tensor is conceptually identical to a numpy array: a ...
