title: Python cannot import DataFrame
body: <p>I am trying to use Pandas in Python to import and manipulate some csv file.</p>
  
  <p>my code is like:</p>
  
  <pre><code>import pandas as pd
  from pandas import dataframe  
  data_df = pd.read_csv('highfrequency2.csv')
  print(data_df.columns)
  </code></pre>
  
  <p>But there is an error :</p>
  
  <pre><code>ImportError: cannot import name DataFrame
  </code></pre>
  
  <p>I have Pandas in Python, and I think dataframe comes with Pandas. </p>
  
  <p>So, anyone can tell me what does this error message mean ?</p>
  
  <p>Thanks </p>
