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.
