title: Importing pandas shows ImportError: cannot import name hashtable
body: <p>I have installed pandas on python 3.3, and coded like this:</p>
  
  <pre><code>import csv
  import pandas
  from pandas import DataFrame
  
  csvdata = pandas.read_csv('datafile.csv')
  df = DataFrame(csvdata)
  </code></pre>
  
  <p>It comes with the following error message:</p>
  
  <pre><code>cannot import name hashtable
  Traceback (most recent call last):
    File "C:\Users\document\test4.py", line 5, in &lt;module&gt;
      import pandas
    File "C:\Python33\lib\site-packages\pandas\__init__.py", line 6, in &lt;module&gt;
      from . import hashtable, tslib, lib
