text: Using Tutorial Data from Google Drive in Colab
  ==============================================
  
  We've added a new feature to tutorials that allows users to open the
  notebook associated with a tutorial in Google Colab. You may need to
  copy data to your Google drive account to get the more complex tutorials
  to work.
  
  In this example, we'll demonstrate how to change the notebook in Colab
  to work with the Chatbot Tutorial. To do this, you'll first need to be
  logged into Google Drive. (For a full description of how to access data
  in Colab, you can view their example notebook
  `here <https://colab.research.google.com/notebooks/io.ipynb#scrollTo=XDg9OBaYqRMd>`__.)
  
  To get started open the `Chatbot
  Tutorial <https://pytorch.org/tutorials/beginner/chatbot_tutorial.html>`__
  in your browser.
  
  At the top of the page click **Run in Google Colab**.
  
  The file will open in Colab.
  
  If you choose, **Runtime** then **Run All**, you'll get an error as the
  file can't be found.
  
  To fix this, we'll copy the required file into our Google Drive account.
  
  1. Log into Google Drive.
  2. In Google Drive, make a folder named **data**, with a subfolder named
     **cornell**.
  3. Visit the Cornell Movie Dialogs Corpus and download the ZIP file.
  4. Unzip the file on your local machine.
  5. Copy the file **movie\_lines.txt** to **data/cornell** folder you
     created in Google Drive.
  
  Now we'll need to edit the file in\_ \_Colab to point to the file on
  Google Drive.
  
  In Colab, add the following to top of the code section over the line
  that begins *corpus\_name*:
  
  ::
  
      from google.colab import drive
      drive.mount('/content/gdrive')
  
  Change the two lines that follow:
  
  1. Change the **corpus\_name** value to **"cornell"**.
  2. Change the line that begins with **corpus** to this:
  
  ::
  
      corpus = os.path.join("/content/gdrive/My Drive/data", corpus_name)
  
  We're now pointing to the file we uploaded to Drive.
  
  Now when you click on the **Run cell** button for the code section,
  you'll be prompted to authorize Google Drive and you'll get an
  authorization code. Paste the code into the prompt in Colab and you
  should be set.
  
  Rerun the notebook from **Runtime** / **Run All** menu command and
  you'll see it process. (Note that this tutorial takes a long time to
  run.)
  
  Hopefully this example will give you a good starting point for running
  some of the more complex tutorials in Colab. As we evolve our use of
  Colab on the PyTorch tutorials site, we'll look at ways to make this
  easier for users.
