title: Converting object column in pandas dataframe to datetime
body: <p>I have an object column in a pandas dataframe in the format dd/mm/yyyy, that I want to convert with to_datetime.</p>
  
  <p>I tried to convert it to datetime using the below:</p>
  
  <pre><code>df['Time stamp'] = pd.to_datetime(df['Time stamp'], format= '%d/%m/%Y')
  </code></pre>
  
  <p>I get the following errors:</p>
  
  <pre><code>TypeError: Unrecognized value type: &lt;class 'str'&gt;
  ValueError: unconverted data remains:  
  </code></pre>
  
  <p>Does this mean that there is a blank row somewhere, I have checked the original csv and I cannot see one.</p>
