./source/vstoxx_data_31032014.h5`` does not exist
<p>I am using ipython to compile my code, but I am faced with an error.</p>

<p>My code is the following:   </p>

<pre><code>import pandas as pd
h5=pd.HDFStore('./source/vstoxx_data_31032014.h5','r')
futures_data=h5['futures_data']
options_data=h5['options_data']
h5.close()
</code></pre>

<p>And the OS error is:</p>

<blockquote>
  <p>OS error ./source/vstoxx_data_31032014.h5`` does not exist</p>
</blockquote>

<p>How do I overcome this problem?</p>
