title: TypeError: 'str' object is not callable with path
body: <p>I am facing this issue, but I couldn't figure out why because I don't know where something changes to str. I am using python 3.6 . This function is supposed to detect a face.</p>
  <p>The error is detected in this line</p>
  <p><strong>person_name = os.path.basename(os.path.normpath(path(path)))</strong></p>
  <p><strong>Code:</strong></p>
  <pre><code>    def extract_face(path_to_filename, detector, required_size=(160, 160), save_faces=True):
          image = Image.open(path_to_filename)
          image = image.convert('RGB')
          pixels = asarray(image)
          results = detector.detect_faces(pixels)
