title: OSError: Initializing from file failed on csv in Pandas
body: <p>So far <code>pandas</code> read through all my CSV files without any problem, however now there seems to be a problem..</p>
  
  <p>When doing:</p>
  
  <pre><code>df = pd.read_csv(r'path to file', sep=';')
  </code></pre>
  
  <p>I get:</p>

  <p>Other files in the same folder that are XLS files can be accessed without an issue. </p>
  
  <p>When using the Python library like so:</p>
  
  <pre><code>import csv
  file = csv.reader(open(r'pathtofile')) 
  
  for row in file:
      print(row)
      break
  
  df = pd.read_csv(file, sep=';')
  </code></pre>
  
  <p>the file is being loaded and the first line is printed. However I get:</p>
  
  <blockquote>
    <p>ValueError: Invalid file path or buffer object type: </p>
  </blockquote>
  
  <p>Probably because I can't use <code>read_csv</code> this way...</p>
  
  <p>How to get the first <code>pandas</code> function to work? The csv does not contain any special characters except German ones. The filesize is 10MB.</p>
