title: Python Pandas does not read the first row of csv file
body: <p>I have a problem with reading CSV(or txt file) on pandas module
  Because numpy's loadtxt function takes too much time, I decided to use pandas read_csv instead.</p>
  
  <p>I want to make a numpy array from txt file with four columns separated by space, and has very large number of rows (like, 256^3. In this example, it is 64^3).</p>
  
  <p>The problem is that I don't know why but it seems that pandas's read_csv always skips the first line (first row) of the csv (txt) file, resulting one less data.</p>
  
  <p>here is the code.</p>
  
  <pre><code>from __future__ import division
  import numpy as np
  import pandas as pd
  ngridx = 4
  ngridy = 4
  ngridz = 4
  size = ngridx*ngridy*ngridz
  f = np.zeros((size,4))
  a = np.arange(size)
  f[:, 0] = np.floor_divide(a, ngridy*ngridz)
  f[:, 1] = np.fmod(np.floor_divide(a, ngridz), ngridy)
  f[:, 2] = np.fmod(a, ngridz)
  f[:, 3] = np.random.rand(size)
  print f[0]
  np.savetxt('Testarray.txt',f,fmt='%6.16f')
  g = pd.read_csv('Testarray.txt',delimiter=' ').values
  print g[0]
  print len(g[:,3])
  </code></pre>
  
  <p>f[0] and g[0] that are displayed in the output have to match but it doesn't, indicating that pandas is skipping the first line of the <code>Testarray.txt</code>.
  Also, length of loaded file <code>g</code> is less than the length of the array <code>f</code>.</p>
  
  <p>I need help.</p>
  
  <p>Thanks in advance.</p>
