title: Cloud AI Platform Training Fails to Read from Bucket
body: <p>I'm trying to use Cloud AI Platform for training (gcloud ai-platform jobs submit training).
  I created my bucket and am sure the training file is there (gsutil ls gs://sat3_0_bucket/data/train_input.csv).</p>
  
  <p>However, my job is failing with log messsage:</p>
  
  <pre><code>File "/root/.local/lib/python3.7/site-packages/ktrain/text/data.py", line 175, in texts_from_csv
      with open(train_filepath, 'rb') as f:
  FileNotFoundError: [Errno 2] No such file or directory: 'gs://sat3_0_bucket/data/train_input.csv'
  </code></pre>
  
  <p>Am I missing something?</p>
