PyTorch 深度学习：60分钟入门

Author: Soumith Chintala

What is PyTorch?

PyTorch is a Python-based scientific computing package serving two broad purposes:

• A replacement for NumPy to use the power of GPUs and other accelerators.

• An automatic differentiation library that is useful to implement neural networks.

Goal of this tutorial:

• Understand PyTorch’s Tensor library and neural networks at a high level.

• Train a small neural network to classify images

To run the tutorials below, make sure you have the torch, torchvision, and matplotlib packages installed.
