.. _sec_colab:

Using Google Colab
==================


We introduced how to run this book on AWS in :numref:`sec_sagemaker`
and :numref:`sec_aws`. Another option is running this book on `Google
Colab <https://colab.research.google.com/>`__, which provides free GPU
if you have a Google account.

To run a section on Colab, you can simply click the ``Colab`` button to
the right of the title of that section, such as in
:numref:`fig_colab`.

.. _fig_colab:

.. figure:: ../img/colab.png
   :width: 300px

   Open a section on Colab



When it is the first time you execute a code cell, you will receive a
warning message as shown in :numref:`fig_colab2`. You may click "RUN
ANYWAY" to ignore it.

   The warning message for running a section on Colab



Next, Colab will connect you to an instance to run this notebook.
Specifically, if GPU is needed, such as when invoking the
``d2l.try_gpu()`` function, we will request Colab to connect to a GPU
instance automatically.

Summary
-------

-  You can use Google Colab to run each section of this book with GPUs.

Exercises
