title: I'm unable to upload files to my Jupyter Notebook on Google Colab
body: <p>On the Files tab on the left I click the Upload button to upload a file called <code>titanic_train.csv</code>. However, the image goes to the <em>bottom</em> of the files tab and just stays there, never becoming accessible to my programs,</p>

  <p>As a workaround, I also tried uploading via Google Colab's built-in <code>google.colab.files.upload</code> method, which successfully prompts me for a file, but then stalls at 0% uploaded with the message:</p>
  
  <pre><code>titanic_train.csv(text/csv) - 72499 bytes, last modified: 9/20/2018 - 0% done
  </code></pre>
  
  <p>Viz,</p>

  <p>Does anyone have an idea of what I may be doing wrong, or how I could resolve this so my programs can successfully access files via Google Colab?</p>
  
  <p>I'm doing this with Chrome on Ubuntu 16.04. </p>
