title: reading csv file with tensorflow
body: <p>In the examples. the variables for the columns in data set are manually given.
  But my data set already has the names as headers. I want to use them. How to get the header names of a .csv file using tensor flow using python?</p>
  
  <pre><code>import tensorflow as tf
  filename_queue=tf.train.string_input_producer(
  ['final_data1.csv'],num_epochs=1) 
  #to reada the csv file----- 
  print(5) 
  reader = tf.TextLineReader(skip_header_lines=1) 
  print(4)
  _, csv_row = reader.read_up_to(filename_queue)
  print(type(csv_row)) 
  print(3)
  with tf.Session() as sess: 
      print(reader.num_records_produced()) 
      tf.global_variables_initializer() 
      coord = tf.train.Coordinator() 
      threads = tf.train.start_queue_runners(coord = coord)'
  </code></pre>
